I’ve previously written about open online courses you can take to develop your skills in user experience design. I’ve also talked about how this knowledge can be used and abused when it comes to cyber security.
If you want to build a solid foundation in interaction design, I recommend The Encyclopedia of Human-Computer Interaction. This collection of open source textbooks cover the design of interactive products, services, software and many many more.
I’m proud to be one of the contributors to the newly published Cyber Security: Law and Guidance book.
Although the primary focus of this book is on the cyber security laws and data protection, no discussion is complete without mentioning who all these measures aim to protect: the people.
I draw on my research and practical experience to present a case for the new approach to cyber security and data protection placing people in its core.
Check it out!
To support my firm’s corporate and social responsibility efforts, I volunteered to help NSPCC, a charity working in child protection, understand the Internet of Toys and its security and privacy implications.
I hope the efforts in this area will result in better policymaking and raise awareness among children and parents about the risks and threats posed by connected devices.
Toys are different from other connected devices not only because how they are normally used, but also who uses them.
For example, children may tell secrets to their toys, sharing particularly sensitive information with them. This, combined with often insufficient security considerations by the manufacturers, may be a cause for concern.
Apart from helping NSPCC in creating campaign materials and educating the staff on the threat landscape, we were able to suggest a high-level framework to assess the security of a connected toy, consisting of parental control, privacy and technology security considerations.
Cyber security is a manpower constrained market – therefore the opportunities for AI automation are vast. Frequently, AI is used to make certain defensive aspects of cyber security more wide reaching and effective: combating spam and detecting malware are prime examples. On the opposite side there are many incentives to use AI when attempting to attack vulnerable systems belonging to others. These incentives could include the speed of attack, low costs and difficulties attracting skilled staff in an already constrained environment.
Current research in the public domain is limited to white hat hackers employing machine learning to identify vulnerabilities and suggest fixes. At the speed AI is developing, however, it won’t be long before we see attackers using these capabilities on mass scale, if they don’t already.
How do we know for sure? The fact is, it is quite hard to attribute a botnet or a phishing campaign to AI rather than a human. Industry practitioners, however, believe that we will see an AI-powered cyber-attack within a year: 62% of surveyed Black Hat conference participants seem to be convinced in such a possibility.
Many believe that AI is already being deployed for malicious purposes by highly motivated and sophisticated attackers. It’s not at all surprising given the fact that AI systems make an adversary’s job much easier. Why? Resource efficiency point aside, they introduce psychological distance between an attacker and their victim. Indeed, many offensive techniques traditionally involved engaging with others and being present, which in turn limited attacker’s anonymity. AI increases the anonymity and distance. Autonomous weapons is the case in point; attackers are no longer required to pull the trigger and observe the impact of their actions.
It doesn’t have to be about human life either. Let’s explore some of the less severe applications of AI for malicious purposes: cybercrime.
Social engineering remains one of the most common attack vectors. How often is malware introduced in systems when someone just clicks on an innocent-looking link?
The fact is, in order to entice the victim to click on that link, quite a bit of effort is required. Historically it’s been labour-intensive to craft a believable phishing email. Days and sometimes weeks of research and the right opportunity were required to successfully carry out such an attack. Things are changing with the advent of AI in cyber.
Analysing large data sets helps attackers prioritise their victims based on online behaviour and estimated wealth. Predictive models can go further and determine the willingness to pay the ransom based on historical data and even adjust the size of pay-out to maximise the chances and therefore revenue for cyber criminals.
Imagine all the data available in the public domain as well as previously leaked secrets through various data breaches are now combined for the ultimate victim profiling in a matter of seconds with no human effort.
When the victim is selected, AI can be used to create and tailor emails and sites that would be most likely clicked on based on crunched data. Trust is built by engaging people in longer dialogues over extensive periods of time on social media which require no human effort – chatbots are now capable of maintaining such interaction and even impersonate the real contacts by mimicking their writing style.
Machine learning used for victim identification and reconnaissance greatly reduces attacker’s resource investments. Indeed, there is even no need to speak the same language anymore! This inevitably leads to an increase in scale and frequency of highly targeted spear phishing attacks.
Sophistication of such attacks can also go up. Exceeding human capabilities of deception, AI can mimic voice thanks to the rapid development in speech synthesis. These systems can create realistic voice recordings based on existing data and elevate social engineering to the next level through impersonation. This, combined with other techniques discussed above, paints a rather grim picture.
So what do we do?
Let’s outline some potential defence strategies that we should be thinking about already.
Firstly and rather obviously, increasing the use of AI for cyber defence is not such a bad option. A combination of supervised and unsupervised learning approaches is already being employed to predict new threats and malware based on existing patterns.
Behaviour analytics is another avenue to explore. Machine learning techniques can be used to monitor system and human activity to detect potential malicious deviations.
Importantly though, when using AI for defence, we should assume that attackers anticipate it. We must also keep track of AI development and its application in cyber to be able to credibly predict malicious applications.
In order to achieve this, a collaboration between industry practitioners, academic researchers and policymakers is essential. Legislators must account for potential use of AI and refresh some of the definitions of ‘hacking’. Researchers should carefully consider malicious application of their work. Patching and vulnerability management programs should be given due attention in the corporate world.
Finally, awareness should be raised among users on preventing social engineering attacks, discouraging password re-use and advocating for two-factor-authentication where possible.

My book has been translated into Persian by Dr. Mohammad Reza Taghva from Allame Tabatabaee University and Mr. Saeed Kazem Pourian from Shahed University. Please get in touch if you would like to learn more.
Augusta University’s Cyber Institute adopted the book “The Psychology of Information Security” as part of our Masters in Information Security Management program because we feel that the human factor plays an important role in securing and defending an organisation. Understanding behavioural aspects of the human element is important for many information security managerial functions, such as developing security policies and awareness training. Therefore, we want our students to not only understand technical and managerial aspects of security, but psychological aspects as well.
It’s been a pleasure delivering a talk on the psychology of information security culture at the SANS European Security Awareness Summit 2016. It was the first time for me to attend and present at this event, I certainly hope it’s not going to be the last.
The summit has a great community feel to it and Lance Spitzner did a great job organising and bringing people together. It was an opportunity for me not only to share my knowledge, but also to learn from others during a number of interactive sessions and workshops. The participants were keen to share tips and tricks to improve security awareness in their companies, as well as sharing war stories of what worked and what didn’t.
It was humbling to find out that my book was quite popular in this community and I even managed to sign a couple of copies.
