Enemy Unknown: Handling Customised Targeted Attacks

 

Detecting and preventing customised targeted attacks in real-time

Experts design computer security products to detect and protect against threats such as computer viruses, other malware and the actions of hackers.

A common approach is to identify existing threats and to create patterns of recognition. This is similar to the way the pharmaceutical industry creates vaccinations against known biological viruses. Or police issuing wanted notices with photographs of known offenders.

Detecting the unknown

The downside to this approach is that you have to know in advance that the virus or criminal is harmful. The most likely time to discover this is after someone has become sick or a crime has already been committed. It would be better to detect new infections and crimes in real-time and to stop them in action before any damage is caused.

The cyber security world is adopting this approach more frequently than before.

Deep Instinct claims that its D-Client software is capable of detecting not only known threats but those that have not yet hit computer systems in the real world. These claims require a realistic test that pits the product against known threats and those typically crafted by attackers. Attackers who work in a more targeted way. Attackers who identify specific potential victims and move against them with speed and accuracy.

Electioneering

This test report used a range of sophisticated, high-profile threat campaigns such as those directed against the US Presidential election in 2016. It also directed targeted attacks against victim systems using techniques seen in well-known security breaches in recent months and years.

The results show that Deep Instinct D-Client provided a wide range of detection and threat blocking capability against well-known and customised targeted attacks. It didn’t interfere with regular use of the systems upon which it was deployed.

The deep learning system was  trained in August 2018, six months before the customised targeted threats were created.

Predictably Evil

A common criticism of computer security products is that they can only protect against known threats. When new attacks are detected and analysed security companies produce updates based on this new knowledge. It’s a reactive approach that can provide attackers with a significant window of opportunity. Some use special technology to predict the future, but does AI really work?

AV is dead (again)

It’s why anti-virus has been declared dead on more than one occasion.

Latest report now online.

Security companies have, for some years, developed advanced detection systems, often labelled as using ‘AI’, ‘machine learning’ or some other technical-sounding term. The basic idea is that past threats are analysed in deep ways to identify what future threats might look like. Ideally the result will be a product that can detect potentially bad files or behaviour before the attack is successful.

(We wrote a basic primer to understanding machine learning a couple of years ago.)

Does AI really work?

So does this AI stuff really work? Is it possible to predict new types of evil software? Certainly investors in tech companies believe so, piling hundreds of millions of funding dollars into new start-ups in the cyber defence field.

We prefer lab work to Silicon Valley speculation, though, and built a test designed to challenge the often magical claims made by ‘next-gen’ anti-malware companies.

With support from Cylance, we took four of its AI models and exposed them to threats that were seen in well-publicised attacks (e.g. WannaCry; Petya) months and even years later than the training that created the models.

It’s the equivalent of sending an old product forward in time and seeing how well it works with future threats. To find out how the Cylance AI models fared, and to discover more about how we tested, please download our report for free from our website.

Review: ImmuniWeb On-Demand Application Security Testing

We review the on-demand application security testing service from ImmuniWeb.

What do a start-up, small business and enterprise have in common?

They all have one or more websites.

That’s not a very humorous punchline, but the security implications of managing business websites aren’t funny either.

What is Machine Learning?

… and how do we know it works?

What’s the difference between artificial intelligence and machine learning? Put simply, artificial intelligence is the area of study dedicated to making machines solve problems that humans find easy, but digital computers find hard. Examples include driving cars, playing chess or recognising sarcasm.
