- Air-gapped networks: Pros, cons, and jumping the air-gap.
Nov 12, 2019
What is Air-Gapping?
Similar to the medical term ‘quarantine’, an air-gapped computer or network is physically separated from other computers or networks. To explain further, an air-gapped computer is not physically or digitally (no Wi-Fi) connected to the Internet, nor to any external device. Air-gapping assumes that every other network or device is a threat in an effort to provide a heightened level of security. For data to move across the air-gap, it needs to be physically transferred using an alternative data storage medium, such as a USB drive. Air-gapped networks are closed systems, with input and output under strict controls.
Air-gapping can be setup in a variety of businesses and government agencies at a reasonably low cost, in terms of infrastructure. So long as the network remains unconnected, it is further protected from malicious actors working externally to the infrastructure. Most frequently, air-gapping is used in environments that deal with classified or highly sensitive information, such as military or government systems, financial systems like stock exchanges, life-critical systems, and industrial control systems.
What’s the catch?
The most obvious downside is that maintaining the air-gapped data can be labour intensive. Manual data transfer may lower productivity, which has a flow-on effect of becoming more expensive to run. Due to the lack of direct connectivity to the Internet, the system won’t automatically receive software updates, including security patches, antivirus updates, and so on, which leaves systems with vulnerabilities that can be leveraged by malicious actors. The installation of updates requires manual data transfer, which has its own risks as discussed in the next section.
In an air-gapped network, no remote connection from the outside world should be available. This can slow down recovery if a situation occurs where there has been a fault that is affecting operations and an engineer or developer is then required to attend to the system ASAP. Instead of being able to remotely access the network, they are required to be on-site, affecting recovery times from incidents outside business hours. By allowing a remote connection program in a network, it no longer is considered air-gapped and now potentially accessible to external malicious actors.
Jumping the Air-Gap
The biggest threat to any system is the people who have access to it. Insider threats, such as disgruntled staff members, may seek to disrupt or steal the data that exists within the protected system. However, gaining physical access doesn’t mean the threat has to be in the same room. Instead, sometimes they are able to use the behaviour of other people to gain access to the air-gapped network.
In 2010, the malicious computer worm ‘Stuxnet’ was targeted at air-gapped Iranian nuclear facilities through infected USBs. This malware was specifically crafted to take advantage of a string of zero-day vulnerabilities to infect systems, propagate itself, and look for the system it was designed to target. This was the first in a string of similar malware types (such as ‘Flame’, ‘Duqu’, and more recently, ‘Brutal Kangaroo’), which are crafted to infect every USB plugged into the compromised computer with the expectation that, eventually, one of them would be connected to the air-gapped network.
Once the target system has been infected, data exfiltration methods can extend to properties that are native to the machine, including light and sound (i.e. LEDs and hardrives using morse code), which can be monitored from a distance. None of this means that air-gapping has lost relevance.
While there are cons to running an air-gapped environment and there are demonstrated ways in which to jump the gap, systems disconnected from the greater world of the Internet remain one of the most secure ways to protect data. Due to the complexity of bypassing the air-gap and exfiltrating data, air-gapping a network is still a valid way for a company to establish a strong layer of defence for sensitive systems or data.

- Samuel Sentongo, Alcorn Group’s NSW Technical Area Manager
Nov 6, 2019
The expansion of the Information Security (InfoSec) industry in recent years has brought with it an increase in demand for skilled and experienced security professionals to provide expert consulting. To address this demand, Alcorn Group, a CyberCX Company, has expanded its presence in Sydney with Samuel Sentongo (pictured), the NSW Technical Area Manager. He is Alcorn Group’s eyes and ears on the ground in NSW, running the daily operations; including onsite testing, rapid response, consulting with our clients in Sydney, as well as, working in Business Development. Samuel enjoys the challenge of solving the unique problems that exist in the InfoSec industry, with a panache for mobile applications testing, especially in terms of new and developing areas.
In order to get to know him better, we sat down with Samuel and asked him some questions about his previous experience, the InfoSec industry, and what drives him. Read his responses below: “I have answered candidly, these are my thoughts and my truth.”
Where does your passion for the InfoSec industry stem from and how did you get into the industry?
There was no one light bulb moment that did it for me. My first exposure to the InfoSec industry was through the movie Hackers. I fell in love with the notion of the “genius hacker” but soon found out that there is more to it than that. What is not shown are the hours put in, in the pursuit of ‘genius’. My life took a detour through a Bachelor of Engineering because, at that time, there was no degree for InfoSec, and my parents, who had raised a family of engineers, thought IT was inferior (Thanks Samuel Sentongo Sr). During my time at Multimedia University, I met two lecturers who worked part-time in InfoSec. They encouraged me, brought training to the university at their own cost, and mentored me. I can’t stress the importance of mentors enough in this industry. For my industrial placement internship, I went for an InfoSec job, even though I had only two subjects related to IT in my degree.
My sister told me, “if you have a one in a thousand chance of getting a job, apply 1000 times”, so that’s what I did. I applied to every InfoSec company on earth (I have the proof!). I applied to all of them, whether they had vacancies or not. (I did get some interesting responses which I am saving for my autobiography 😊.) In the end, two people took a chance on me (Sarah Oquist and Saurabh Sarawat) and the rest is history.
What skills are you bringing to the Alcorn Group team? Any unique approaches that you like to take to solve the problems that the industry faces?
Nothing unique here, just plain old fashioned hard work, grit, willingness to learn, a “leave my ego at the door” attitude, admit when I am wrong, perseverance, and getting things done, is what it is all about at the end of the day. I am not a ‘Rockstar hacker’ and I don’t intend to be one.
While the IT industry has a non-typical workplace culture, I am incredibly keen and invested in helping improve the diversity of the people in the industry. I have skin in the game, not just for people of different race or social origin, but also future generations. Women were the first en masse coders, and in Bletchley Park (do your Googles) women constituted 75% of the workforce which was responsible for Britain’s WW2 cryptanalysis effort including breaking the ENIGMA machine.
Where do you see yourself making the biggest impacts for AG, and the industry as a whole?
Alcorn Group has given me the opportunity to be myself, grow the business and set the tone for how things are done in NSW through autonomy, mastery of my skillsets, and purpose. In terms of the industry, I honestly do not know, time will be the judge.
If I focus on my craft, apply myself, be the best version of me I can, and uplift the people/network around me, then I can be a positive influence. If I can speak and live my truth, then, I will kindle ideas, and light the fires that will make the biggest impact. We always have to question the world around us and challenge thoughts, to grow both as a person, and as a business.
I want to help Alcorn Group to nurture crazy ideas that actually work and make breakthroughs in the industry. Whether a product that is new on the market (insert buzzword here), or a new way of doing business, and adding value for the customer. Alcorn Group aspires to be a place of innovation, coming up with ideas and breakthroughs, while commercialising them at the same time. Alcorn Group has the aspirations to be the employer of choice. This can be done by growing the pipeline of talent and being the ambassador for a place where difference of opinion, and diversity of thought is celebrated, not just tolerated.
What are your passions outside of the office?
Outside of the office, I spend most of my time in the gym or going out with friends. I like to try something new every quarter: last time it was acting and improv, before that rowing but now I am signing up for Spanish classes, as well as, getting back into swimming with the change in the weather. Doing things that scare me is the name of the game and you can only grow once you are outside of your comfort zone. The next new thing I want to practice is meditation and mindfulness.
Having a dedicated Sydney team allows Alcorn Group to have greater onsite utilisation and reduces response time for onsite requests. With his attitude and grit, towards learning and working, not only is Samuel successfully chasing his dream, he is also constantly proving he is a valuable asset to clients, to team members, and to Alcorn Group. By providing a unique and tailored service to clients, Alcorn Group is able to help NSW government departments and companies alike, improve their security maturity and position.

Oct 27, 2019
Deepfakes are video, and/or audio that have been altered to misrepresent reality, most often by using the face of a famous person doing or saying something that they did not. While having roots in the very late 20th century, it is only recently that the sophistication of deepfakes has progressed to photorealistic levels. It was not until a 2017 report, in Vice magazine, did the wide mainstream media picked up on the phenomena.
In the very short amount of time since that initial report, the machine learning technology deepfakes employ has moved at breakneck speed. Algorithmic face-swaps which, in 2017, required hundreds of images and many days of processing has recently been accomplished with a single image and within seconds.
A recent development out of Samsung’s research department has developed a new technique where, in place of training the algorithm to fix one face onto another using a collection of expressions from one individual, the new algorithm uses facial structures that are shared by the majority of people to puppeteer a new face. In this fashion, the Samsung researchers have been able to animate pictures and paintings, such as the Mona Lisa.
Attempts to have a machine give an audibly realistic reading from text have been the goal of many. Numerous companies, across industries, are invested in this research, including tech giants, game companies and navigational software providers. Producing realistic audio clips that are possible of ‘bringing the dead to life’ or taking existing samples of real people and having them ‘read’ text, has been around since the start of the century and have only become more believable and more accurate.
Even with technology bounding ahead, low-tech techniques such as slowed-down video or splicing audio snippets, labelled as ‘cheapfake’ or even ‘dumbfake’, which are easy to make with real content being ‘doctored’, can still be found entering the media.
The danger deepfakes pose as a disinformation tool is a major concern to many and has yet to be addressed from a legislative standpoint. Deepfakes have become a pervasive, international sensation, but platform moderation and legislation have failed to keep up, instead relying on the interpretation of existing codes such as those present for identity theft, cyberstalking and revenge videos.
Now that the technology has moved along, the cost and ease of producing a deepfake video is trivial. The cost of recognising deepfake videos, on the other hand, grows with the increasing difficulty involved to identify them. Since humans are quite poor at being able to recognise forgeries, it becomes more imperative that digital solutions be developed. These programs can utilise a range of techniques, although what works in one instance may not work on the next. One of the most promising tools looks at the target’s mouth. While various parts of the film may or may not be faked, the mouth is nearly always altered, to fit the audio, and ‘tells’ may be more obvious. Unfortunately, this tool remains far from accurate and requires further development before it can be used with accuracy.
Into the future
While laws may come into place that target deepfakes specifically, they are more likely to fall under the umbrella of current legislation. It could be expected that with the technology to create deepfakes getting ever cheaper, more realistic and harder to detect by consumers, that media industries will embrace the techniques. ‘Hiring’ separate faces, voices and movement actors that fit a role more fully than that capable by a single individual will be too hard to pass up, especially if it works out to be increasingly lucrative. The higher the proliferation of deepfakes, the more cybersecurity measures, such as detection tools and algorithms, will need to be brought to bear on the issue. At this point in time there are limited technologies available, although that is unlikely to remain the case for long if an initiative from Facebook and Microsoft called the Deepfake Detection Challenge bears fruit.

- Drupal Applications and Web Crawlers
Oct 22, 2019
Many companies that are looking to establish a digital presence create a website which customers can access and interact with to learn more about the business. However, externally accessible IT assets have the potential of presenting security risks to these organisations. In order to better assist an organisations’ understanding of potential security risks, Alcorn Group have recently conducted research into the detection of application fingerprinting for a common application framework, Drupal.
Drupal is an open source Content Management System (CMS) designed to support the development of web applications stored on remote servers, which deliver content through a browser interface. Many companies use Drupal to create customised web applications for user account creation and management, as well as content delivery. Drupal is the 4th most popular open source CMS in Australia and has over 9000 customers. Overall, it is known for its stability and security, however like many other Content Management Systems, there are several known vulnerabilities within versions of the CMS which can be exploited.
How Attackers May Exploit Drupal
Attackers often employ automated tools to crawl the internet for sites which meet certain conditions that can be exploited. By further fingerprinting vulnerable web applications, an attacker can determine which known exploits can be used. Depending on the content within the application and its functionality, web applications can expose user information, company documentation, staff information, or other personally identifiable information.
Why is Logging and Monitoring Important?
The source of an attack can be quite difficult, or near impossible to determine if no logging occurs. A lack of logging and monitoring also contributes to attacks being unnoticed for extended periods of time. Consequently, an attacker’s presence may persist during this time, with access to the information available within the application, such as user data. Additionally, there are liability risks associated with companies who fail to effectively control and mitigate these risks. To combat this, it is possible to use logging and monitoring tools to capture all requests made to an application. However, this often creates large files filled with information that may or may not be useful in identifying malicious behaviour.
What Can be Done?
Due to the difficulties associated with manually logging and monitoring all traffic requesting responses from a single web application, it is important to use a centralised system to ensure nothing is missed. A centralised logging server gathers logs in a single location for further assessment, while also assisting to prevent logs from being altered should they be compromised. Centralised logging typically improves the overall security posture of an organisation, as it not only assists with identifying network activity, but allows ‘normal’ traffic to be identified. This in turn aids in identifying any abnormalities when they occur. Additionally, centralised logging increases the integrity of data logged by ensuring a complete history of logs exist, which is a crucial part of a mature Incident Response process.
How to Detect
The use of centralised logging ensures a convenient single location where logs for numerous devices can be monitored and assessed. For example, the Elastic Stack, or ELK Stack, is a combination of three open source projects which take log data from any source and allow the user to search, visualise, and analyse the data in real time. By monitoring the incoming request data using Elastic Stack, an organisation can find unusual activity on their network, diagnose errors, and recover from attacks.
Overall, centralised logging to an external logging system, combined with after-hours alerting and monitoring, ensures that a robust and complete log history can be captured and maintained. A follow up blog post will dive into the research conducted by Alcorn Group in identifying Drupal scans using the ELK Stack.

- It Also Runs Doom
Oct 15, 2019
While conducting research into ATM functionality and exploitation, Alcorn Group staff have confirmed that Doom (1993) can indeed run on the machine.
Since the release of the original source code from publisher id Software in 1997, the legendary first-person shooter Doom has been ported to a myriad of devices by fans, including a Kodak digital camera, LED billboard, Siglent SSA 3021X Spectrum Analyser, and so on. While some devices can natively run the code, porting Doom often involves exploiting device firmware. This is regularly served as an incentive for research into device exploitation, and similarly, provides a benchmark for further research within Alcorn Group into ATM vulnerabilities.

- Consequences of Improper Data Destruction
Oct 2, 2019
What is Data Destruction?
It is the intentional, permanent and irrevocable removal of data. Specifically, digital data stored on memory storage devices, which include data storage, mobile devices, and Internet of Things (IoT) devices. If the data is not properly cleansed then personal and/or confidential information such as photos, company documents, emails, invoices, and passwords can be recovered.
Why is it Necessary?
Data management and destruction decisions occur throughout the information life cycle. Data destruction is a fundamental part of a holistic and mature approach to governing information, and paramount in preventing sensitive data from being accessed by unauthorised persons. Although data has a high value in most businesses, it also has an ongoing maintenance cost and may be subject to policies that necessitate destruction. Studies conducted within the field of media and data recovery demonstrate how easily data can be retrieved, even after efforts have been made to cleanse the storage device. While some cases of unwanted recovery of data occur when a device is lost, a larger number of instances can be attributed to the improper disposal of data due to inadequate cleansing.
Improper Data Destruction
With a multitude of brands and devices offering data destruction services to the end user, it is unsurprising that users may make misinformed decisions on the disposal of data. Two of the most popular and misunderstood options, which do not result in data erasure, are formatting and factory reset. These methods are primarily used for preparing new devices for use however, they always leave recoverable files as only metadata (which can point to the location of data) is removed. Information left behind after attempted destruction is known as data remanence which can cause unintentional leaks of sensitive information. There are many common ways to recover data, such as simply restoring a file from the recycle bin, or using programs to identify files that can be ‘found’ through signature-based analysis which recognises common file formats. Data on magnetic media can also be retrieved if it is overwritten only once, by direct observation with an electron microscope.
Proper Data Destruction
There are three common methods of data destruction that are more permanent:
Data Erasure - The process of overwriting data to reduce the likelihood of its retrieval from a storage device. There are physical methods for magnetic media, such as degaussing (applying strong magnetic fields to disrupt stored data) and heating (bringing the disk above the Curie point, where it becomes non-magnetic). Data erasure can also be achieved using software, which writes random, empty, or patterned data in order to destroy any evidence of the original data.
Cryptographic Erasure - Where strong full-disk encryption (FDE) has been used to guard the contents of a storage device, this method erases the key material which could be used to decrypt the data. Once the key material is securely erased, the data stored on the encrypted volume is no longer able to be read.
Physical Destruction - The process of physically shredding hard drives, smartphones, printers, laptops and other storage media into tiny pieces, making it extremely difficult, if not impossible to re-assemble.
It is worth considering the value of information stored on personal and professional devices over their operating life. Choosing an appropriate disposal method to protect that data should be part of the documented life cycle of these devices. At an organisational level, appropriate policies on data storage, encryption, retention and destruction should be implemented. This can aid in mitigating the high costs associated with data breaches such as loss of customer trust, breach of regulation, financial loss, and other preventable occurrences.
Alcorn Group has experience in a range of governance, risk and compliance services including conducting reviews of data management policies to aid in mitigating these risks.

- Threat Intelligence Service with Alcorn Group
Sep 18, 2019
Here at Alcorn Group, we pride ourselves on consistently delivering high-quality products to all our clientele. Threat intelligence can prepare, prevent and identify threats which look to take advantage of any organisation. This is accomplished by keeping organisations informed and up-to-date on new and existing threats, which in turn reduces overall threat activity, lowers risk, and capitalises on security expenditure.
What is Threat Intelligence?
Cyber threat intelligence is evidence-based knowledge inclusive of; details of the circumstances, known malicious processes, general symptoms, and action-oriented advice about existing or emerging threats to assets. The key areas of information collection require exploration and analysis through rigorous and structured techniques, this gives the consumer vast quantities of information which promotes accurate and relevant intelligence.
Why You Need Threat Intelligence
A threat intelligence service delivers an improved defensive posture, helps to protect against zero day threats, lowers risk, reduces reaction times and gets the most out of security expenditures. With Alcorn Group’s considerable human resources focused on these crucial concerns, our clients can realise increased savings in financial and human capital while having enhanced security measures in place.
What is Threat Intelligence Used for?
Threat intelligence gives context around security issues that helps with informed decision making. Knowledge gained through threat intelligence is used to prevent, discover, and navigate incidents of data loss or network compromise. The information can also be scrutinised to supply further context for threat analysis (i.e. who is attacking and why), data investigation (identifying issues) and uncovering malicious activity on networks. In the event that malicious activity on a network is discovered, expertise can be focused to bolster security incident response capabilities.
What Does a Threat Intelligence Service Provide?
Good data governance involves having a security profile, which is a set of rights and restrictions associated with particular users. The profile determines the actions such as viewing, creating and modifying that a user can perform. An Intelligence service assists in enforcing the security profile of an organisation, identifying deviations in the profile and contributes to:
- Providing additional context and relevance to threats and can assist in attribution.
- Allowing for informed decision-making during, and post, security incidents.
- Enabled proactive operational security capability.
- Results in augmented detection of sophisticated vulnerabilities within the organisation.
- Empowering organisations to develop a proactive security posture and assist in developing overall risk management policies.
How is a Threat Intelligence Service Conducted?
The service will look at the internal and external aspects that are relevant to the client using, among other tools, cyber threat diagnostics. To build a profile of the client, internal intelligence is employed to highlight areas of focus and provide specific information into the external monitoring component. Internal threat intelligence is appropriate for detecting insider threats such as rogue employees.
External sources of intelligence that Alcorn Group use includes:
- Publicly available threat feeds (paid and free services).
- Closed threat feeds from partner organisations, including other security providers.
- Information gathered by Alcorn Group consultants using:
- OSINT (open source intelligence)
- SOCMINT (social media intelligence)
- HUMINT (human intelligence)
If you would like to know more about the threat intelligence services offered by Alcorn Group and how it can help your business, please call 1300 368 806.

- Multi-Factor Authentication for Beginners
Sep 5, 2019
Multi-factor authentication (MFA) refers to using two or more independent credentials to prove the identity of a user. It decreases the likelihood of accounts being stolen as it increases the difficulty of authentication. Many applications and accounts use protections based upon the following three stages:
- Identification – how a user is identified, typically through a username.
- Authentication – how a user proves their identity, typically through something they know, something they own, or something they are.
- Authorisation – the set of activities that the user is allowed to perform.
Multi-factor authentication focuses on increasing the strength of the authentication stage, which can be verified by the following factors: Something the user knows, something the user owns, or something the user is.
Something the User Knows
This may be a password or a PIN that the user remembers. It can also be the answer to a ‘secret’ question, such as, “What is your father’s middle name?”
Something the User Owns
This may be a mobile phone number, a swipe card or fob, a bank card, a USB key generator, or a token generator.
Something the User is
This is usually something that is biometric in nature, such as a fingerprint, retinal image, or voice.
So Why Use Multi-factor Authentication?
Combining two different factors of authentication increases the assurance of a legitimate user’s request for access as they have to declare multiple unique identifiers. This makes it harder for an attacker to authenticate as a legitimate user as they must have access to more information and/or items owned by the user.
In May this year, Google posted statistics (read here) based on multi-factor authentication, where they found “On-device prompts, a more secure replacement for SMS, helped prevent 100% of automated bots, 99% of bulk phishing attacks and 90% of targeted attacks.”
An article posted by Alex Weinert (read here), the Group Program Manager for Identity Security and Protection at Microsoft, puts forward that “… your account is more than 99.9% less likely to be compromised if you use MFA.” In the article, Alex encourages everyone to go turn on MFA, stating that once an attacker gains access to your password, “…the attacker must try logging in with the compromised password, and at that point MFA is your safeguard”.
Alcorn Group recommends that administrative actions should always pass through at least one multi-factor authentication process. At a minimum, multi-factor authentication should be implemented as part of remote access to Internet accessible systems.

- How Alcorn Group Cracks Passwords
Jul 24, 2019
In recent years, there has been an increase in data breaches affecting upwards of hundreds of millions of users each time a company is compromised, some of which have been due to weak passwords. You may be inclined to believe that a sophisticated and experienced hacker is responsible for these events. However, with the appropriate hardware being utilised, password ‘crackers’ can run automatically, tasked with revealing passwords.
Alcorn Group’s Password Hash Cracker
Here at Alcorn Group, we have built a computer system specifically for performing brute-force attacks and cracking password hashes. The system is utilised by our security consultants to attempt to crack any hashes accessed during engagements. More commonly, it is used on Red Team engagements when the consultant can access and retrieve user hashes from Active Directory. The components utilised for this system build are listed below, consisting of off-the-shelf hardware:
- Intel i5 CPU
- 32GB RAM
- Gigabyte H110-D3A (Bitcoin Mining) Motherboard
- Corsair AX1600i Power supply (running at capacity)
- 4 x Gigabyte GeForce RTX 2080TI’s
- 1 x Asus Geforce GTX 1080
- 1 x Asus GTX 960
- 6 x PCI-E USB3.0 Risers
- Hydra III 8 GPU Case
As a result of the enormous computational power this system offers, it is capable of running through every possible 8-character long NT LAN Manager (NTLM) password hash within five and a half hours, as demonstrated below:
However, by adding only one additional character to the password (9-characters) it took approximately 100 times longer to crack, a total of 21 days and 13 hours:
These statistics indicate just how important length is when determining a password. Increasing the length by an additional letter increases the time exponentially.
How Can You Secure Your Password?
While password security and complexity requirements can be written into the code of the application, the responsibility of maintaining a secure password falls to every individual user. To limit the chances that your passwords will be cracked, the National Institute of Standards and Technology (NIST) offers the following guidelines for password complexity:
- An eight-character minimum and 64-character maximum length
- The ability to use all special characters but no special requirement to use them
- Restrict sequential and repetitive characters (e.g. 12345 or aaaaaa)
- Restrict context specific passwords (e.g. the name of the site, etc.)
- Restrict commonly used passwords (e.g. [email protected], etc.)
- Restrict passwords obtained from previous breach corpuses
For additional protection, it is also highly recommended that the following are taken into consideration:
- Avoid context-specific words. For example, if you work as a Corrections Officer, avoid using the word ‘Officer’.
- Avoid words found in a dictionary. Common words from dictionaries are frequently tried first.
- Use passwords in conjunction with Multi-Factor Authentication (MFA), biometrics, or single sign-on (SSO) systems.
- Avoid reusing passwords across different services to reduce the chance of compromise on multiple accounts.
- Think about utilising passphrases instead of passwords. Passphrases contain multiple words which form a memorisable phrase which is not easily guessed and is an easy method of increasing the length.
Good password hygiene is the key to ensuring that your systems are secured. The more complex and difficult to guess your password is, the safer it is from malicious attackers and their tools. One method of ensuring this, is to utilise a password management tool. Password management tools are easily available and are a quick and safer method for keeping all your passwords in one secure place. By combining a strong long pass phrase to gain access to the tool, local encryption of passwords, and a built in password generator that can generate strong, unique and long passwords for you automatically, your passwords will become exponentially safer without the need to memorise all of them.
What is a Password Hash?
Successful password cracking depends heavily on the robustness of an application’s password security mechanisms. To assist in protecting against data breaches, storing passwords securely is essential when developing a new piece of infrastructure or application, however, it is often overlooked. Hashing passwords is a common approach to achieving this extra layer of security.
A hash is a one-way function that generates a representation of data (in this case, a password), using an algorithm to map the data, or password of any size to a fixed length representation. For example, when a user signs up for an account, the chosen password is stored as the generated hash, rather than the actual characters that the user typed. When the user attempts to log in with their password, the entered password is passed through the same hash function and then compared to what is stored in the application’s database. If the two hashes are the same, the user is granted access to the application. This method offers an alternative to the storing of passwords in plain text, adding extra complexity for a malicious attacker if they were ever retrieved during a data breach.
What is a Brute Force Attack?
Hashing a password is not enough protection to stop a malicious attacker, as brute-force attacks can be conducted with an appropriate degree of computational power. Brute-force attacks can be used to crack passwords by running a program that calculates each and every possible password combination, hashing it before comparing it to the hashed password that is being cracked. Once the two hashes have been matched, the password is known, or cracked.
What is Salting?
To assist in combating password cracking, hashes can be ‘Salted’. Salting is an additional layer of protection where a unique value is added to a password before it is hashed, creating a different hash value. Hash functions are designed in such a way that the slightest change to the input (the password to be hashed) drastically affects the output. Therefore, salting a password prior to hashing it complicates the password cracking process. The malicious attacker would require the unique salt value for that particular password in addition to the password hash to retrieve the password.
Alcorn Group is committed to continual investment in password security. We will continue to utilise hardware such as our password hash cracker during engagements in order to crack simple passwords, educating our clients on the importance of password security.

- Red Teaming Stories: How Secure is Your Swipe Card?
Jul 17, 2019
Entering your office building in the morning is generally an effortless task. Business operations continue throughout the day uninterrupted, knowing that the premises is secured by multiple layers of authorisation required for entry. These systems ensure that only select personnel may enter, with that trust typically represented by an access card, fob, or token associated with the individual. These small items grant the user with what is highly sought after by any malicious attacker - privileged access.
These devices typically use Radio Frequency Identification (RFID), a form of contactless authentication which can permit or deny physical access to specific locations. RFID readers are usually located on the outside of a building, on a doorway, or within an elevator, and are universally used within most offices, as well as government buildings. To work correctly, a RFID reader has an antenna coiled inside of it, sending out radio signals searching for cards or devices that enter within its range. Once inside this range, the RFID device is energised and responds back with the device’s credentials, including a unique identifier. The reader then sends this information electronically to a command station which will indicate to approve or deny the user.
While other security measures are normally paired with this system (such as physical security, manually gated access, security cameras, or elevator restrictions to user access levels), the overall security of the organisation is only as strong as its weakest point. Malicious attackers will continuously look for holes within the overall security of an organisation. Focus is placed on elements in isolation, particularly on identifying any overlooked element, no matter how small. For example, an entry point with swipe card access but no additional security monitoring provides an opportunity to perform reconnaissance on the RFID system, as well as any additional requirements needed for entry.
Through observing door traffic, an attacker may identify a target who has access to an entry point of interest and make attempts to clone their card. This is not always a straightforward process and often requires multiple attempts. Due to the low first-time success rate, an attacker may have to loiter outside of the building and make attempts to clone multiple people’s cards. This increases the likelihood that physical security management and staff are able to thwart these cloning attempts as they are trained in identifying people who do not belong, or who are exhibiting abnormal behaviour. However, if an attacker is successful in cloning a card, they have gained privileged access.
Powered by a concealable battery, the card cloning device can capture and decode data, running a wireless access point for a secondary device to connect to. This secondary device attaches to a commercial card reader, allowing data to be written to a blank card. Once the device is turned on, it can pick up any RFID card within its range of approximately 0-40cm, depending on the strength of the signal. This makes card cloning difficult to detect, as physical proximity is standard in crowded places such as public transport, organised seating, and elevators. In addition, many people store their building passes in accessible areas, such as around their necks or on their hips, allowing for cloning to occur inconspicuously.
Alcorn Group’s Red Team methodology involves consultants simulating a malicious attacker, sometimes using this specific method to gain unauthorised access to the target organisation’s physical premises. One of our senior consultants has created a ‘weaponised’ RFID card reader, which allows RFID-enabled tokens to be wirelessly cloned in the field. This gadget, like others of its kind, can be used by security testing teams to asses facilities exposure to these sorts of attacks.
Multiple layers of physical security controls as well as security awareness training are key to ensuring your organisation can effectively prevent unauthorised physical access. In support of all employees remaining vigilant to security control weaknesses, all employees should be aware of physical and environmental controls protecting their company’s premises. This should include awareness training on tailgating, as well as vetting visitors and always have them be escorted around the premises. It is important to layer security measures across all entry points of a premises by pairing active security cameras with all swipe access entry points. In addition, where active security patrols are adopted, these should practice a hard-to-predict patrol schedule. Additional training for physical security management and staff should involve awareness of this type of threat, as well as knowledge of procedures to follow in response to incidents of this nature reported to them. RFID blocking card holders are also a useful tool to deter malicious attackers swiping valid credentials.

- Notorious Ransomware GandCrab Retired After Decryptor Released
Jun 26, 2019
A recently notorious ransomware, GandCrab has finally been retired by developers after a decryptor has become publicly available. Like most ransomware, this has targeted organisations and individuals indiscriminately. While it has undergone many iterations since its release in ‘the wild’, the primary function has remained the same - Encrypt victims files and exfiltrate sensitive information, offering a key to decrypt these files for an exorbitant fee, payable through Cryptocurrency of indiscernible origin (Dash, in this instance).
GandCrab followed a Ransomware as a Service (RaaS) model, in which it was sold to affiliates who shared 60% of the revenue and could also access victim information which included IP addresses, domain information, operating system details and so on. Over 5 core versions of this malware were distributed via various malware campaigns, spam emails, exploit kits and fake torrenting sites. Each version aimed to answer solutions released to decrypt malware-infected files. This included basic encryption methods in its first iteration, leading to a later version which leveraged a method of DLL/EXE execution (Invoke-ReflectivePEInjection) within the victim’s Powershell process, without writing to disk. Characteristically similar to other ransomware, obfuscated scripts were presented to the victim to be downloaded, which then decoded a URL pointing to the download of GandCrab, unbeknownst to the user.
Since its creation and release, according to GandCrab developers, this ransomware campaign has earned over $2 billion dollars in revenue from roughly 50,000 devices within the last two months. The alleged success of this ransomware can be attributed to the developer’s persistence in meeting mitigating patches with newer, more effective versions of the malware, distributed sometimes within hours upon a fix. This back-and-forth between patching and malware updates finally ceased after GandCrab developers officially halted the malware at version 5.2, boasting a “well-deserved retirement” in response to the release of the Bitdefender’s decryptor.
Alcorn Group has observed this variant of ransomware amongst others through various Incident Response (IR) engagements. Ransomware is exceptionally damaging to individuals and organisations alike, posing a multitude of significant business risks when new strains are identified due to the tenacity attackers take to ensure a ransom is paid.
Ransomware can never be trusted, no matter what lengths criminals will take to convince their victims that their files will remain unencrypted after payment. Even if a ransom is paid, it is likely that sensitive data stored in a compromised system has already been exfiltrated. Newer, more sophisticated and damaging strains of ransomware can surface suddenly, as demonstrated within GandCrab’s lifecycle.
If you, or your organisation, has encountered GandCrab, please refer to Bitdefender’s decryptor. Contact us for more information on how ransomware can affect your organisation, and what to do in the event of malware infection.

- Red Teaming Stories: Is That Really a Conference Call?
Jun 18, 2019
When it comes to conducting a successful red team exercise, it often involves building a level of trust against the target organisation. This trust will allow the consultant to exploit weaknesses in people and immature business processes, to gain access to systems, infrastructure or physical locations. Some activities used to build trust with an organisation may involve weeks of preparation through reconnaissance. This preparation builds confidence for the consultant during the physical attack stage of the exercise. For example, confidently tailgating into a building or facility, as the consultant has in-depth knowledge of the target environment prior to arriving.
Alcorn Group have a proven track record of delivering quality red team engagements through our client base. Our methodology covers several techniques used during these engagements to ensure success and quality for our clients. An example of such techniques to build this trust is using fake conference calls. Often physical access can be quite tedious (especially for smaller locations), where finding a vacant desk or room can be troublesome due to foot traffic. Alcorn Group frequently use phones to avoid conversation and gain access to a meeting room.
To take this a step further, Alcorn Group consultants have developed a service to streamline this process and add some flexibility. It can be used by anyone on an active engagement where physical assets are in scope. The service provides auto-answering ‘conference’ type calling capability, which will auto-play background noise, like that of a conference call. The consultants can then put this on speaker in a meeting room while they proceed to target the conference equipment and any other devices in the room.
Should a staff member walk in on the consultant attending the ‘conference’ call, they can inform the simulated call that they need to wrap up and can continue the call later. This adds to the story and will allow the consultant the ability to discretely leave and re-establish somewhere else. This technique can also be used to challenge people who may accuse you of being in the wrong location, using the conference call as context as to why you are there.
This is just one of the many techniques the consultants at Alcorn Group use, amongst their repertoire of knowledge and experience, to ensure that they deliver a successful and quality Red Team Engagement.

- Information Security and Resilience in Australia’s Critical Infrastructure
Jun 11, 2019
As you wake up in the morning, you finally convince yourself to leave the warmth and comfort of your bed, only because there is an equally warm shower waiting for you. You proceed with your daily routine, brewing yourself a hot coffee and walking to catch the bus into work. No thought goes into these conveniences provided to you and the critical infrastructure that facilitates them.
Food, water, health, communications, transportation and banking all have one thing in common - they all represent parts of Australia’s critical infrastructure. Critical infrastructure has become the backbone of a functioning society worldwide, not just within our homes. It underpins our Australian society and economy and is integral to the prosperity of the nation.
Now, take a moment to imagine if a cyber attack was to occur on just one of these critical infrastructure facilities. There would be no running water for your shower, no electricity to brew your morning coffee, or perhaps no bus to take you to work. National security risks to critical infrastructure are becoming increasingly complex and have continued to evolve over recent years. Rapid technological changes are taking place all the time, such as the introduction of Internet of Things (IoT) devices or more specific to critical infrastructure, Operational Technology (OT) devices. These devices introduce a growing number of threats to critical infrastructure systems and facilities as they become cyber connected.
Within Australia, the Critical Infrastructure Centre coordinates the management of the national security risks that face Australia’s critical infrastructure. The centre works with state and territory regulators to help identify and mitigate risks, primarily focusing on sabotage, espionage and coercion in the telecommunications, electricity, gas, water and ports sectors.
In addition, the Security of Critical Infrastructure Act 2018 assists in the management of these national security risks posed by foreign involvement in Australia’s critical infrastructure within the electricity, gas, water and ports sectors. The Act aligns with the government-business partnership approach, that underpins Australia’s Critical Infrastructure Resilience Strategy. It ensures that the Government has all the information necessary to conduct national security risk assessments, by introducing three measures:
- An asset register to provide the Government visibility of who owns and controls these assets, enabling better targeting of our risk assessments.
- The ability to obtain more detailed information from owners and operators of assets in certain circumstances to support the work of the Centre.
- The ability to intervene and issue directions in cases where there are significant national security concerns that cannot be addressed through other means.
Here at Alcorn Group, we have extensive and proven experience in providing various types of security assessments on facilities and infrastructure alike. As highlighted in one of our previous articles (which you can read about here), Alcorn Group has accumulated experience in conducting successful red team engagements on utility facilities which provide critical infrastructure to the local community. Alcorn Group also has the ability and skills required to conduct various types of infrastructure security assessments to assess the resilience of IoT and OT devices used in relation to critical infrastructure.
Whether it is through providing a thorough Red Team engagement, or by conducting an infrastructure security assessment, Alcorn Group is committed to accurately identifying risks and providing tailored remediation steps to assist in the protection of many government critical infrastructure facilities.
Get in touch with the Alcorn Group team to discuss how we have assisted organisations with the development of their cyber security resilience in the past, and how your organisation can benefit from these strategies.

- Red Teaming: Do you really know your organisation's security posture?
Jun 4, 2019
When you think of criminals, images of shady figures in balaclavas and baseball caps brandishing weapons usually come to mind. Certainly not the vaguely familiar, well-dressed person that you kindly held the door open for as you entered the office this morning.
In fact, recalling what this person looked like stirs unremarkable images, not out of the ordinary for a typical contractor who would visit the office on occasion. The last thing that comes to mind when recalling this figure is “Criminal infiltrating the organisation to steal confidential information”, when it’s more likely they just work in an area of the business you are not familiar with from time-to-time.
Alcorn Group recently bypassed the physical security of a company who provides critical infrastructure in a test to assess the effectiveness of the organisation’s security controls. For this client, the Red Team Engagement involved physical infiltration of a utility facility, which ultimately resulted in Alcorn Group gaining internal corporate network access. Later this week, Alcorn Group will be presenting to the client about this engagement, while working with them further to develop improvements to their Cyber Security posture and resilience, including awareness for the importance of physical security controls in relation to Cyber Security.
Typically, a Red Team Engagement combines social engineering, physical entry, and digital exploitation, yet it can also involve other techniques depending on the target and resources available. Red Team Engagements are essential for organisations who endeavour to understand exactly where their security posture stands, and any unknown business risks , while providing broader education and engaged awareness across all areas of the business.
Through a multi-layered approach, Alcorn Group’s Red Team Engagements assist clients with gaining visibility of Cyber Security risks that have the potential to impact their organisation, with a focus on exposing vulnerabilities and risks that would be posed by different, real-world Cyber attackers who would try to infiltrate the network. Alcorn Group has accumulated extensive experience in delivering Red Team Engagements to Government organisations and facilities around critical infrastructure assets, including companies within the banking and financial sectors.
Get in touch with the Alcorn Group team to discuss how Red Team Engagements can help further develop your organisation’s Cyber Security resilience, and to identify any potentially impacting risks.

- CPS 234 Protects the Financial Services Industry (and you)
May 29, 2019
Information security is a constantly evolving and dynamically changing landscape of threat and risk. Organisations that manage significant amounts of Personally Identifiable information (PII) and personal financial information are a particularly attractive target. Unfortunately, in many cases APRA-regulated organisations of all sizes have historically found it challenging to achieve traction with information security initiatives, resulting in broad risk to the financial services industry and associated stakeholders (e.g. fund customers and members). To help with addressing this, APRA released draft Prudential Standard CPS 234 Information Security (CPS 234) in March 2018. This prudential standard sought to ensure that APRA-regulated entities have in place sufficient information security capabilities to ensure resilience against security incidents (e.g. data breaches). The final version of the standard was released in November 2018 and, following industry consultation, comes into effect on 1st July 2019.
CPS 234 applies to all APRA-regulated entities and applies equally regardless of the organisations size and capability. APRA-regulated entities include:
- banks, building societies and credit unions
- life and general insurance and reinsurance companies
- private health insurers
- friendly societies and superannuation funds (excluding self-managed funds).
When considering compliance to CPS 234, APRA-regulated entity must address nine distinct information security areas. These area are as follows:
- Roles and responsibilities – Defining the board and Individual responsibilities for information security
- Information security capability - Measuring and validating on an ongoing basis that the organisation can maintain information security
- Policy framework – Implementing and maintaining foundational organisation policy elements such as risk management, acceptable use, human resource security, change management etc.
- Information asset identification and classification – classifying all information based on criticality and sensitivity
- Implementation of controls – implementing the technical, managerial and operational controls necessary to achieve and maintain the security of information including those managed by third parties. Examples of controls are encryption, backup solution, security awareness training, documented procedures and guidelines etc.
- Incident management – defining and implementing a framework for managing and responding to a security incident when they occur to ensure incident are contained, eradicated, and that the impacted assets are recovered
- Testing control effectiveness – implementing a systematic approach to making sure the implemented controls are suitable and fit for purpose commensurate with the threat landscape, the type of information to be protected, the consequences of an incident and the regularity of change
- Internal audit – establish or extend an internal audit program to provide information security assurance to the board
- APRA notification – defined requirement for APRA to be notified no later than 72 hours after becoming aware of a reportable information security incident. CPS 234 also requires that APRA be notified no later than 10 days after becoming aware of a material security control weakness that can not be resolved in a timely manner.
In defining these requirements, CPS 234 varies from being highly prescriptive, to largely subjective in what it requires. As a result, some organisations may find it challenging to assess compliance. Where this is the case Alcorn Group recommends:
- Understanding the organisation’s core business goals and establish information security objectives that align and are supportive
- The Board should realise and take responsibility of information security and then define individual roles within the organisation to achieve these objectives
- Identification of the critical and important information, and information processing facilities
- The board should support initiatives to protect the information security of critical information assets
- Establishing information security Key Performance Indicators (KPIs) and measure the current state. The board is then able to set KPI target to influence information security and define leadership requirement for success.
For a further guidance on achieving compliance with CPS 234, APRA have released draft prudential practical guide CPG 234, with the final version expected to be released prior to the CPS 234 effectives date (1st July 2019).

- Personal Internet of Things Device Security
May 20, 2019
Door locks, coffee machines, security cameras, dryers, alarm clocks, and thermostats. At first glance it is difficult to discern what commonality these devices share from an end customer’s point of view. In previous years, some of these devices would not have shared a lot in common at all. However, now, almost all industries are selling devices connected to the Internet that are automating processes within the home and workplace. With the flood of devices coming onto the market, it is important to understand how devices can have an impact on the security posture of individuals purchasing these products.
Due to the large number of manufacturers rushing to connect their devices to the Internet, security features on IoT devices are highly variable. While there are steps being taken to standardise IoT frameworks, the high variability of security across devices at present makes it difficult for consumers to determine their security posture. As a result, organisations and people alike can be caught out owning, and potentially relying on, a device that is vulnerable to manipulation.
For example, a wi-fi connected printer increases the attack surface of a home network by being accessible from an external location. Printers can be vulnerable due to insufficient authentication or authorisation. They may display personally identifiable information publicly, or they may have insecure software on their system. If proper controls are not in place, the printer can become a gateway for an attacker to deploy malicious software on, or pivot to attacking the network.
A number of strategies can be employed to harden the security posture of IoT devices within the home. The following is by no means an exhaustive list, but it does provide a high-level overview of how one can protect their IoT devices in the home:
Embrace Network Segmentation and Segregation
Network segmentation involves splitting your network into a number of sub-networks, which impedes lateral movement through the network. Network segregation involves placing rules on which devices can communicate with each other. If IoT devices have only limited access to the other portions of a network, this can limit the ability for an attacker to leverage vulnerabilities.
Change Default Passwords
Where authentication is available on IoT devices, altering the default password should be made a priority. Default passwords may lack the complexity required to be secure, and in some cases, may be widely publicised on the Internet. Choose new passwords that are long and strong, and unique from all other passwords.
It’s important to make certain that connected systems are also protected with secure and unique passwords. This means that if one device gets compromised, there is a greater amount of difficulty in reaching other systems on the network. See our article ‘Creating Secure Passwords’ for more information about how to create a strong and memorable password.
Change Default Usernames
Where the default username is able to be altered, it’s a good idea to change it. This means it’s harder for attackers to identify the account with the most privileges.
Set User Privileges
User accounts should be set to the least amount of privilege required. Additionally, user accounts should use the highest privacy settings and enable multi-factor authentication where available.
Enable Account Lockouts
If there is functionality to lock user accounts out after a certain number of tries, this should be enabled. This can hinder attackers who attempt to use brute-force attacks against passwords.
Enable Automatic Updates
Patching is the most effective way to protect a device from known software vulnerabilities, so long as it remains in support. It is good practice to set up IoT software to receive automatic updates if possible, as it means that vulnerabilities will be addressed in a timely manner.
Limit Administrative Capabilities
Disable or remove any unrequired functions that any IoT device provides. This limits the ability for attackers to leverage weaknesses that may be present in those unused functions.
Encrypt Your Transmissions
If your system has the security options to encrypt transmission, it is good practice to set encryption to an accepted standard, such as AES-256, and enable HTTPS where it’s available.
For further guidance on IoT security, OWASP has a comprehensive breakdown from a number of perspectives. See https://www.owasp.org/index.php/IoT_Security_Guidance for more information. The IoT Alliance Australia (IoTAA) also has an IoT security guideline, which provides guidance of where security and privacy in IoT devices currently stands. It can be found here: https://www.iot.org.au/wp/wp-content/uploads/2016/12/IoTAA-Security-Guideline-V1.2.pdf
While the above strategies and methods can be employed to increase security of IoT devices in the home, it becomes increasingly difficult to mitigate vulnerabilities for IoT devices in other industries such as health care or logistics. For example, devices that have less consumer-based options and/or support, such as insulin pumps, or pacemakers. For people owning these devices, it imperative that a thorough risk analysis of devices is completed, and that support and maintenance of these devices are ongoing.
The practice of security of IoT devices is still developing as the industry itself matures. The first wave of devices have come to market in a “fail fast, fix later” mindset, and it is imperative that moving forward, a more security conscious approach is taken.

- Release of OAIC Notifiable Data Breaches Scheme 12-month Insights Report
May 14, 2019
The Office of the Australian Information Commissioner (OAIC) has released its first full-year insights on notifiable data breaches that were reported between April 2018 to March 2019. Key results highlight that of the 964 eligible breach notifications reported:
- 580 (or 60%) were attributed to malicious or criminal attacks.
- Of those 580, 394 (or 68%) were cyber incidents resulting from common threats such as phishing, malware, ransomware, brute force attacks, compromised or stolen credentials and other forms of hacking.
- The remaining 186 (or 32%) of those 580 were the result of theft of paperwork or a data storage device, social engineering or impersonation, or an act of a rogue employee or insider threat.
These annualised results continue to support our previous article published back in July 2018. It remains relevant for organisations to better protect the personal information they hold, through establishing a regular program of security assessment and testing. Identifying and remediating vulnerable targets before they are compromised will always be a key defence against data breaches.
Alcorn Group specialises in performing vulnerability assessments and penetration testing, which combined with our other services such as red teaming, threat risk assessments, and incident planning and response, can provide a broad and effective means to assist with mitigating the risk of data breaches. Please contact us to discuss how we can best address your organisation’s needs.

- Transport Encryption Recommendations
May 7, 2019
Transport Layer Security (TLS), the successor protocol to Secure Sockets Layer (SSL), is the standard security technology for establishing an encrypted link between two systems, such as a web server and a browser, to prevent third parties from reading or modifying transferred information, including personal details. The encryption algorithms used in TLS/SSL scrambles data in transit, making it very difficult to read while it is being sent.
Of all the findings Alcorn Group raises, weak TLS/SSL configuration is one of the most frequent. Using insecure protocols or weak cryptography undermines the intent of the security measures in place and leaves data accessible to prying eyes.
In this blog post, we are shining a light on our preferred practices.
There are currently six protocols in the SSL/TLS family: SSL v2, SSL v3, TLS v1.0, TLS v1.1, TLS v1.2, and TLS v1.3. Published in August of 2018 (RFC 8446), the latest encryption protocol, TLS v1.3, was released with a redefined handshake protocol which simultaneously speeds up communication and protects downgrade attacks. However, since its release a group of researchers have successfully performed a downgrade attack on TLS v1.3 when RSA ciphers are in use.
Although there is a known vulnerability, at the time of writing, TLS v1.3 is the best protocol to use as it significantly reduces attack vectors compared to previous versions. Crucially, it also removes obsolete features from TLS v1.2, including SHA-1, RC4, DES, 3DES, AES-CBC, MD5, Arbitrary Diffie-Hellman groups, and EXPORT-strength ciphers. Cipher suites are defined differently to previous versions and do not specify the certificate type or the key exchange mechanism. Due to its recency, it is not yet supported on all browsers.
TLS v1.2 and TLS v1.3 support Authenticated Encryption with Associated Data (AEAD). This encryption provides simultaneous assurances on confidentiality, integrity and authenticity of the data. Therefore, when deploying servers, TLS v1.3 should be the default protocol, with TLS v1.2 the next preference. There may be a valid business case for use of TLS v1.0 and TLS v1.1 to support older browsers, however, this is sacrificing security for compatibility. It is best to disable support for the deprecated protocols SSL v2 and SSL v3 as these protocols have high levels of insecurity and are vulnerable to Person-in-the-Middle (PitM) attacks.
Where it becomes necessary to support older protocols like TLS v1.0 or SSL v3, consider using TLS_FALLBACK_SCSV. This mode can prevent protocol downgrades from being forced by MitM attackers. Alternatively, specify all protocols that your application is willing to accept.
Certificates should always be obtained from a reliable Certificate Authority (CA). When making the purchasing decision, perform research on how the certificate authority responds to public breaches, as well as how many breaches have occurred. Also important are the services offered. Certificate Authorities should provide a Certificate Revocation List (CRL) and Online Certificate Status Protocol (OCSP) revocation methods.
Your certificate needs to be properly validated against its hostname. If the Common Name (CN) of the certificate is different from the hostname, it becomes more difficult for users to verify the authenticity and identity of the web server. A mismatched certificate nullifies the use of SSL, and an attacker could then establish a Person-in-the-Middle attack against the remote host without changing the user experience.
Of particular note should be the cryptographic algorithms your certificate employs. A certificate will use two pieces of encryption which work hand in hand: the hashing algorithm and the signing algorithm.
Ensure your certificates are hashed with a minimum algorithmic strength of SHA-256 and signed with a minimum* key length of 128-bits in length (symmetric / shared key crypto), or 1024-bits in length for use in key exchange (asymmetric / public key crypto). Currently, the recommended hashing algorithm for a digital certificate is SHA256, with an RSA signing algorithm of a key length of at least 2048 bits.
Bigger is better when it comes to key length and security. However, overly large key lengths will take more power to process.

- New Requirements for Government Agencies under NSW Cyber Security Policy
Apr 29, 2019
In February 2019, the NSW Government issued its new Cyber Security Policy, a key part of its overarching Cyber Security Strategy released in September 2018. The policy establishes a set of mandatory cyber security requirements, ensuring an integrated approach to preventing and responding to cyber security threats.
The policy came into effect on 1 February 2019, requiring all NSW Public Service Agencies to comply with the new requirements. Adoption of the policy, while not mandatory, is also recommended for State Owned Corporations, local councils and universities.
To meet the new requirements, agencies will be required to:
- Ensure cyber security planning and governance is implemented, which includes:
- Establishing clear roles and responsibilities, oversight and plans for cyber security.
- Conducting cyber security risk assessments.
- Establish a cyber security culture across the organisation, incorporating such aspects as:
- Regular education of employees, contractors and outsourced ICT service providers.
- Imbedding cyber security risk management into decision making.
- Manage cyber security risks to protect and secure information and systems, which includes:
- Implementing an Information or Cyber Security Management System and supporting controls, compliant with recognised industry standards.
- Implementing and reporting maturity against the ACSC Essential 8 cyber security incident mitigation strategies.
- Identifying and classifying information and systems, and based on their relative importance, implementing commensurate controls.
- Improve resilience and incident management capabilities, through:
- Maintaining and testing annually, a cyber security incident response plan that integrates with the government’s response plan.
- Implementing adequate incident identification and response tools and processes.
- Reporting cyber security incidents in accordance with requirements.
- Report and attest annually on policy compliance, including reporting on high and extreme residual risks and “crown jewels” (the agency’s most valuable or vital systems and information).
Full details of all new requirements and the overarching strategy can be found in the respective documents linked above. As a CREST certified organisation, Alcorn Group is well positioned to assist government agencies with meeting the new requirements. Our independent assessment services can provide an initial baseline of your organisation’s cyber security posture and actionable recommendations to achieve and demonstrate ongoing compliance. Examples of services directly supporting policy compliance include:

- Technical Writer Speaks at Conference
Nov 15, 2018
Kristine Sihto, technical writer for Alcorn Group, took part in the ‘Write The Docs Australia’ conference in Melbourne this month.
Kristine is a valued member of our quality assurance process, whose role ensures that the written content provided to our clients is both consistent and understandable. Her passion for the written word is evident in her day-to-day interactions with staff. Her topic at Write the Docs – The Art of Consistency: Creating an inhouse style guide – reflects the heart of what she does for Alcorn Group on a daily basis.
We took a few moments to interview Kristine on her role here at Alcorn Group:
A.G.: What does a typical day look like for you?
Kristine: When I get to work, I immediately look for any quality reviews that need to be performed. This involves checking every report for consistent and appropriate language, correct grammar and spelling, and consistent formatting. Once the urgent work is all out of the way, I can then get down to preparing policy and procedure documentation, reviewing marketing, and occasionally writing blog posts.
A.G.: Why did you join Alcorn Group?
Kristine: Alcorn Group was, for me, a huge step in the direction of my lifelong goals. A position working with words has always been my idea of a perfect job, whether that be editing or writing, and in this role, I get to do both every day. I’m also working in a field that I’m passionate about, which is a definite drawcard.
A.G.: What is the thing you like most about your job?
Kristine: This role stretches me in ways I previously couldn’t have envisioned. Information security is an amazing field, and I get to learn things that I would never have considered while working in other industries.
A.G.: What are your biggest professional challenges?
Kristine: I’ve come from a background unconnected to InfoSec or IT, so it’s been a very steep learning curve. Also, while the consultants can collaborate with each other on their technical needs, I have to find my own professional growth strategies and seek out professional networks that support the type of work I do, in addition to the professional networks that support information security.
A.G.: What is your biggest achievement to date – personal or professional?
Kristine: 2018 has been huge for me. I published a book of poetry that I’ve been working on since I was a teen. I’ve spoken at BrisSEC, and now I’ve presented at the Write The Docs conference in Melbourne.
A.G.: What advice would you give to recent new entrants to information security?
Kristine: Find professional organisations to build your network and support your growth. Making connections outside of your organisation means that you have access to a range of professionals who may have the information you need, or know someone to refer you to.

- Release of final version of APRA Prudential Standard CPS 234 on Information Security
Nov 13, 2018
APRA has released the final version of Prudential Standard CPS 234 on Information Security. This follows a period of industry consultation and responses to submissions on the draft standard released back in March 2018
In response to submissions received, APRA has confirmed:
- The new standard will come into effect from 1 July 2019. A transition period for third party arrangements has been allowed whereby requirements will apply from the earlier of the next contract renewal date or 1 July 2020.
- All information assets of regulated entities must be classified in terms of both criticality and sensitivity. This requirement is irrespective of whether information assets are managed by the regulated entity or a third or related party.
- Regardless of whether a third party is in a direct or indirect (downstream) relationship with a regulated entity, and whether the information assets under management form part of a material business activity outsourcing, information assets must be managed in accordance with the new standard.
- Regulated entities must notify APRA within 72 hours of becoming aware of an information security incident. Notifiable incidents are those with either an actual or potential material effect, or those requiring notification to other regulators either in Australia or other jurisdictions.
- Regulated entities must notify APRA within 10 days of becoming aware of a material information security control weakness that is not expected to be remediated in a timely manner.
APRA has also provided further clarification on other requirements in the standard relating to:
- Board information security responsibilities
- Information asset life-cycle
- Annual review and testing of information security response plans
- Nature and frequency of control effectiveness testing commensurate with materiality and frequency of information asset changes
- Reliance on testing of control effectiveness over information assets managed by third or related parties
- The role of internal audit for information assets managed by third or related parties
To assist regulated entities with implementing the requirements of the new standard, APRA will be updating Prudential Practice Guide CPG 234 in the first half of 2019. In preparation, and as recommended in our previous article, regulated entities should assess their current information security control environment, identify any gaps, and develop and execute action plans to address any shortfalls. With its broad scope of security services, Alcorn Group can assist organisations with performing these assessments, as well as provide ongoing support for meeting the new requirements beyond the effective date.

- Halloween comes to Alcorn Group
Oct 30, 2018
Ghosts and goblins and things that go bump in the night! This October 31, webs, spiders, skulls and cauldrons adorned the office, and Alcorn Group staff members got into the spirit of the season by dressing up.
We all know that showing up to the party in the same dress as someone else is a social faux pas of the highest order. While Dale and Callum managed to narrowly avoid the issue with their similar (but different) Apple costumes, imagine the embarrassment when Isaac and Kate both showed up to the office in their matching Sailor Moon outfits!
Extra props to the Sydney office who put effort into their costume despite being so far from the rest of the crew!
A popular vote from staff members decided that Isaac would gain the prize for best dressed, but who do you think wore it better?

- CiscPwn: Hiding the intruder in plain sight.
Sep 27, 2018
Innovation is at the heart of hacking. The hacker’s mindset needs to consider how common items may be manipulated to provide any advantage, whether that’s looking at online presence or finding ways to physically infiltrate an organisation.
Introducing Josh R. - Operations Manager at Alcorn Group, hacker, and innovator, whose customised modification to Cisco phone hardware is assisting our consultants in the field. We call it CiscPwn.
A.G.: What are we looking at, what is this phone device and what can it do?
Josh: We often use devices “implanted” at client networks in order to maintain access. This is a functional computer with hacking tools ready for us to connect remotely and run attacks. We custom made this for a job; the basic build was done in under a day. Since then we’ve added improvements. Typically we’ll build a device for a specific job if needed, then add new features and improvements when we think of them.
A.G.: Why did you choose a phone for the basis of this hardware?
Josh: Lots of spare room, and it fits in at most meeting rooms or desks without raising too many eyebrows. The phone is fully functional, but because it would need to be configured for the PBX at the target, we typically hang the phone on the loading screen so it looks like it’s frozen.
A.G.: Was it difficult to place the device on the site?
Josh: Very easy! When the device looks like it fits in, then it’s normally a matter of plugging it in. We snuck it into a network and used it to maintain remote access. It was very successful.
A.G.: You recently gave a presentation about this device, tell us about that.
Josh: I gave a presentation on Red Team techniques, how to get in the mindset of an attacker. Which for us often comes down to low risk and high success rates. These devices are low risk because they’re difficult to trace, and once we have one implanted there’s a good chance we’ll be able to compromise the network.
A.G.: Are there changes you’d like to make for the next version?
Josh: We have a few improvements to detect tampering and more… but let’s not give it all away.
A.G.: Will Alcorn Group be doing more hardware like this one?
Josh: We have a number of other purpose-built devices already, and whenever we see the need or have an opportunity we add to the list. We can make custom gear for an engagement for sure.
A.G.: What advice do you have for businesses on protecting themselves from hardware like this one?
Josh: Port security and a good asset management policy are key. Asset management and an easy way to identify legitimate items is incredibly important.
A.G.: If someone finds a suspicious piece of hardware like this one on their business premises, who should they contact?
Josh: Ahh, well, roll incident response. …(Have) a good IR plan.
Incident response is a vital piece of the puzzle when safeguarding your systems against intruders. Alcorn Group offer a range of incident response services to fill your needs, ranging from assistance in preparing your IR strategies, determining which areas of your business may require extra attention, or helping you recover in the aftermath of an incident.

- Alcorn Group at Barefoot Bowls
Sep 12, 2018
The Alcorn Group team took to the green at the Merthyr Bowls club this week.
Finger-food was provided for the hungry crew, which all agreed was quite tasty (including the magpie who came to snack while we were playing). Then, breaking into four groups across two lanes, we faced off against each other to see who was the best at rolling balls in a curved line to deliberately miss the things we were aiming at. Which of us could have foreseen that the balls would roll so far, or so askew?
The competition was fierce, with light-hearted heckling to be heard throughout the match. Strategy became key, and at some points players would engage in the meta-game, rolling their ball into blocking positions for the adjoining game, thereby disrupting potential future combatants.
Reece’s Rockin’ Rollers proved strong against Harvey’s Hackers, but Dook’s Divas took the day, finishing off against Kleidon’s Klassics. A great day was had by all.

- Effective Security for Smaller Organisations
Sep 5, 2018
The need for effective security is not just limited to large organisations. Smaller organisations equally need to consider the importance of the information they hold, and the impact to their business and customers if this information fell into the wrong hands or was no longer available.
While there are many best practice standards available to guide good security implementation, their relevance and ability to be applied in smaller organisations may not be clear. This can make it difficult for smaller organisations to determine the scope and extent of security controls that they can practically implement, and whether they have the internal capability to do so.
As highlighted in a recent podcast interview with AEMO’s Chief Security Officer, Tim Daly, standards like the NIST Cybersecurity Framework are available for organisations of all sizes to use. The interview also highlighted partnering with a service provider for assistance where internal expertise may not be available.
How can the NIST framework help? While comprehensive and detailed in nature, the framework still offers a good model for smaller organisations to adopt, being based around a lifecycle approach to cybersecurity-related risk. It aims to guide organisations to:
- Identify the information and services that are important to the organisation
- Protect those important assets through proactively identifying and implementing appropriate security measures at a level appropriate for the organisation
- Detect malicious or unauthorised activities that could put the organisation’s information and services at risk
- Respond to those activities effectively to minimise any impacts
- Recover any impacted information or services in a planned, timely and effective manner.
Still not sure where to start and what to do? Alcorn Group can work with your organisation to perform a NIST capability and gap assessment to help determine your organisation’s current security posture. We can also provide recommendations on appropriate cybersecurity measures to address any gaps and guide you on their implementation. These activities together will help your organisation achieve the first two stages of the NIST framework – “Identify” and “Protect”.
Do you need a trusted partner to perform those ongoing security functions that your organisation does not have the internal capability to deliver? Alcorn Group can tailor a managed security service to fit your organisation’s needs. From effectively planning for and responding to cybersecurity incidents, through to assisting with returning impacted services to normal operations, our managed security service solutions will help your organisation achieve the final three phases of the NIST framework – “Detect”, “Respond” and “Recover”.

- Regulatory Requirement for Aviation Security Identification Card (ASIC) Issuing Bodies
Sep 4, 2018
The Aviation Transport Security Regulations 2005 require issuers of ASICs (“Issuing Bodies” or “IBs”) to establish and implement a program of procedures to ensure they perform functions and exercise powers in an appropriately secure manner. Recent regulatory oversight has highlighted the need to ensure these procedures adequately address how electronic information about ASICs and ASIC applications is handled and stored.
Alcorn Group suggest that IBs ensure that their systems that contain or host ASIC information meet the ACSC Essential Eight and OWASP Top 10 requirements. Alcorn Group also suggest that IBs audit their procedures annually to ensure ongoing compliance. As a CREST certified organisation, Alcorn Group can assist IBs by independently assessing their systems’ compliance through:
- conducting assessments against the ACSC “Essential Eight” mitigation strategies
- performing OWASP “Top 10” assessments and penetration tests of web applications
- assessing and testing other procedures in the IB’s ASIC program.
Alcorn Group can work with IBs to develop an annual independent assessment and testing program that meets the IB’s regulatory obligations, with engagements scheduled throughout the year, and as part of a multi-year program if desired.

- Draft APRA Prudential Standard CPS 234 on Information Security
Jul 17, 2018
In response to the increasing frequency, sophistication and impact of information security attacks, in March 2018, APRA released draft Prudential Standard CPS 234 on Information Security. The proposed standard will require regulated entities to ensure they have effective security controls in place to protect against and respond to such attacks.
Australian regulated entities impacted by the proposed new standard are banks, building societies credit unions, life and general insurance and reinsurance companies, private health insurers, friendly societies and superannuation funds (excluding self-managed funds). The standard broadly covers the following areas that regulated entities will need to address:
- Information security roles and responsibilities
- Information security capability and policy framework
- Information assets and controls, including incident management
- Controls testing and internal audit
- APRA notifications
The consultation period closed in June 2018, and it is expected that the final version of the standard will be released in late 2018. The proposed effective date for the new standard is 1 July 2019.
In preparation, regulated entities will need to assess their current information security control environment, identify any gaps, and develop and execute action plans to address any shortfalls. With its broad scope of security services, Alcorn Group can assist organisations with performing these assessments, as well as provide ongoing support for meeting the new requirements beyond the proposed effective date.

- Creating Secure Passwords
Jul 6, 2018
With the enormous number of passwords we require in our day to day lives, it’s no wonder that people reuse them across multiple sites, or use the minimum complexity they can get away with. How does anyone store that many complex passwords in their head all at once?
A good password is hard to guess but easy to remember. It has uppercase letters and lowercase letters, numbers, special characters, and it is long. It doesn’t include any personal information.
This scares a lot of people, but it doesn’t have to look like this:
On the other hand, it shouldn’t look like this:
Instead, there is another method of creating a good password, called a passphrase. It has uppercase letters and lowercase letters, numbers, special characters, and it is long.
It looks something like this:
The phone sits next to 3 keys. It is on the desk!
Not all password fields will allow spaces; this can be alleviated by using a different character instead of a space.
For example, if I replace the space with the letter z:
A passphrase gains complexity with each element that is included in it, but it remains easy for a human brain to recall. It’s also easier to input without errors than the original complex password shown.
But the program says my password is too long!
Sentences are wonderful things. They vary in length. If the program or website that you’re constructing a password for doesn’t allow a lengthy password, choose a shorter one. Shorter sentences can be memorable, while still having complexity. It’s preferable to aim for the upper margins of what’s allowed, rather than the lower margins. If the program allows for a password of 4-14 characters, choose 14 characters rather than 4, such as in this example:
So why can’t I use this great password everywhere?
It’s important to avoid reusing passwords. Not every organisation will safely store your password, and if you’ve reused passwords and one site gets breached, this can then mean that other sites you use are also affected.
Are there bad passphrases?
Not all passphrases are good to use as passwords. Book or song titles, song lyrics, or commonly known quotes may be present in password dictionaries. However, creating a unique sentence about the things around you will ensure that you’re not treading the same territory that hackers have already covered.
Meanwhile, you can check if your account has been breached by searching at https://haveibeenpwned.com/. This handy service will allow you to see what the breach was, when your account was breached, whether your details were pasted anywhere, and the source of the breach.

- Hacking Windows Domains
Sep 29, 2016
Sydney’s newest go-to security industry conference, PlatypusCon, took place on Sat 24th September. Targeted at infosec enthusiasts of all capabilities and experience, this year’s event took on a fresh approach to conferencing - holding interactive workshops instead of talks, whereby attendees could try their hands at breaking and entering, capturing flags, hacking drones and fuzzing!
Alcorn Group’s managing consultant Lukasz Gogolkiewicz had the pleasure of demonstrating to his 50-strong audience the art of hacking Windows domains. Lukasz’s workshop took attendees on a journey of network service enumeration to identify vulnerabilities, and if possible, establish a foothold on the network. From there, it was a flag capturing mission for points via privilege escalation techniques, domain controller attacks such as password extraction and exploiting misconfigurations in service permissions.
The workshop was received well by the attendees and the opportunity for Alcorn Group to share some of the more intimate techniques behind Windows hacking was appreciated. Keep an eye out on our twitter feed and website for more information on upcoming workshops and training sessions on hacking Windows domains and web applications.

- Oceana CACS Conference
Aug 27, 2016
This year’s Oceania CACS conference is being held on the Gold Coast from September 11 -13. Run by ISACA, this is the premier event in our region for IS Governance, IS Security and IS Assurance professionals.
Alcorn Group’s founder and managing director will be presenting on Monday September 12 at 11:00am with Mayus Nath, Director of QLD Audit Office. With the theme of this year’s conference being ‘Governance, Empower, Protect’ Mayus and Wade will present to the audience their thoughts on empowering the use of new technologies by understanding attacks on Critical Infrastructure with Advanced Persistent Threats (APT’s).
With information technology becoming more and more pervasive, not only in enterprises but also in social and public settings, organisations need to embrace new technologies, including Internet of Things in order to enter the market and be competitive. However, until recently, protection has been focussed on information system. Wade and Mayus will discuss how organisations need to take a broader view now days, incorporating multiple technologies when designing and implementing security. They’ll also take a closer look at why browsers are involved in so many advanced persistence threats (APTs). Attendees will learn more about how web browsers within organisations provide opportunities for attackers.
The program of speakers for this year’s conference should ensure informative and insightful sessions for all attendees. For more information on the 2016 Oceania CACS click here

Mar 5, 2016
Microsoft and ConsenSys partnered back in October 2015 to offer Ethereum Blockchain as a Service (EBaaS) on Microsoft Azure so Enterprise clients and developers could have a single click cloud based blockchain developer environment. The initial offering contained two tools that allow for the development of SmartContract based applications:
• Ether.Camp - An integrated developer environment
• BlockApps - a private, semi-private Ethereum blockchain environment.
Everyone, particularly Financial Services, is interested in Blockchain technology. While a platform like Bitcoin has many great uses specifically as a Cryptocurrency, Ethereum provides the flexibility and extensibility many customers are looking for.
In Financial Services, Blockchain is a major disruptor to some of their core businesses, and FinTech companies are driving innovation in this space. Ethereum is open, flexible can be customized to meet customer needs allowing them to innovate and provide new services and distributed applications or Đapps.
Ethereum enables SmartContracts and Distributed Applications (ĐApps) to be built, potentially cutting out the middleman in many industry scenarios streamlining processes like settlement. But that is just scratching the surface of what can be done when you mix the cryptographic security and reliability of the Blockchain with a Turing complete programming language included in Ethereum.
“Ethereum Blockchain as a Service” allows for financial services customers and partners to play, learn, and fail at a low cost in a ready-made dev/test/production environment. It will allow them to create private, public and consortium based Blockchain environments using industry leading frameworks, distributing their Blockchain products with Azure’s distributed (private) platform.

- ASX and the Blockchain
Feb 6, 2016
The Australian Stock Exchange (ASX) has announced that it has selected US-based firm Digital Asset Holdings to develop solutions for the Australian market utilising Distributed Ledger Technology. This may be able to significantly simplify and speed-up post-trade processing. For ASX clients this could reduce back-office administration and compliance costs, while investors could experience significantly faster settlement of equity transactions – potentially in near real-time.
Adoption of Distributed Ledger Technology has the potential to stimulate greater innovation by ASX and third parties to develop new services for intermediaries, end-investors and listed companies. This would create a more competitive marketplace across a broad range of services.

- Australian Government Cyber Security Review
Jan 27, 2016
Here at Alcorn Group we are eagerly awaiting the release of the 2016 Australian Government Cyber Security Review. The issue of cyber security is one of national importance and affects every Australian citizen, and certainly every Australian business. Some estimates put the direct cost of cyber-crime to Australia a more than $1 billion a year and this seems to be on the conservative side.
There are some great initiatives already including the Australian Information Security Association (AISA) and CREST Australia. The Cyber Security Review will be a clear direction from the federal government and a very much needed clarity. The announcement of funding through to 2019-20 to establish an industry led Cyber Security Centre highlights the government’s efforts to prioritise the area of cybersecurity, and to move towards working more closely with industry, businesses and researchers.
It will be interesting to see how this Security Review evolves and as a wholly Australian owned cyber security company, we are keen to see engagement with Australian industry at a real level. We would like to see initiatives particularly around addressing the skills shortage within the industry that we see at the moment. Our managing director has long been banging on this drum and has been involved in several initiatives to lead Australia’s up-skilling in this area. How government can support Australian businesses to improve their resilience and understanding of cyber threats will also be an area of particular interest. We stay tuned!

- The Australian Crime Commission 2015 Organised Crime Report
May 20, 2015
If you have a spare half hour, make yourself a coffee and have a read through the 2015 ACC Report on Organised Crime in Australia. It makes for an interesting, if not daunting, read. The main things we took away from the report from our perspective.
Cybercrime ain’t going away any time soon and is becoming an increasingly significant factor in many aspects of organized crime
The report extrapolates the cost of cybercrime to Australians this year will be over $936 million.
And this is based only on ACORN self reporting of small-medium businesses, so the report acknowledges this is likely to be an underestimation. We would agree with that- many businesses avoid self reporting, and we all know that cybercrime certainly targets large businesses and government agencies as well, sometimes with devastating impacts. So let’s face it – we are looking at a conservative estimate of over 1 billion dollars this year.
