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.

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

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.)

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.

Hacked! Will your anti-malware protect you from targeted attacks?

The news isn't good. Discover your best options in our latest reports.

Latest reports now online.

Criminals routinely create ingenious scams and indiscriminate attacks designed to compromise the unlucky and, occasionally, foolish. But sometimes they focus on a specific target rather than casting a net wide in the hope of landing something interesting.

Targeted attacks can range from basic, like an email simply asking you to send some money to an account, through to extremely devious and technical. If you received an email from your accountant with an attached PDF or Excel spreadsheet would you open it?

Most would and all that then stands between them and a successful hack (because the email was a trick and contained a dodgy document that gives remote control to the attacker) is the security software running on their PC.

In this test we've included indiscriminate, public attacks that come at victims from the web and via email, but we've also included some devious targeted attacks to see how well-protected potential victims would be.

We've not created any new types of threat and we've not discovered and used 'zero day' attacks. Instead we took tools that are freely distributed online and are well-known to penetration testers and criminals alike. We used these to generate threats that are realistic representations of what someone could quite easily put together to attack you or your business.

The results are extremely worrying. While a few products were excellent at detecting and protecting against these threats many more were less useful. We will continue this work and report any progress that these companies make in improving their products.
