#Cylance antivirus windows 10#
The latest version of Windows 10 build with all security hotfixes installed - This is going to be our target machine.Of course, we would need to set up a test environment to run the scenario. All of this was done on personal interest and curiosity just to confirm whether I could. This is not one of those impractical posts showing the results of a VirusTotal scan against a scratch-coded simple reverse shell to judge whether it’ll pass as the payload for an actual red-teaming engagement and if so terming it as a bypass.īefore we begin I want to make it clear that I was neither employed by any company nor paid by an individual to perform these tests. Yes, I have tried to keep the scenario as real and practical as possible which initiates from the Weaponization phase of the Cyber Kill Chain(if you don’t know what that is here is a link to read up on it).

I did run the scenario and guess what? It was way easier than I thought and it didn’t take me more than 15 minutes to prepare a lure mail with a payload stager that would download and execute our final stage payload to give us the shell. But is it effective? How well does it perform in a real-world assessment? Let’s subject it to such a test to determine that answer, shall we? I would recommend checking their page for more intel on their product which you can do here. All of this is done in the hopes of removing too much dependency on signature-based detection models which have to be frequently updated to keep up with the recent threats and even then it can’t possibly keep up its pace with zero-day threats and previously unseen or evolved malware samples. Basically, it employs ML models which are trained with millions of malicious samples to detect the next threat that comes around using behavioural analysis even if it’s previously unseen. Cylance(now acquired by BlackBerry Limited) belongs to one of the newer waves of security solutions that add a pinch of Machine Learning to existing detection algorithms. So this time I decided to try and run a simulated attack scenario against a host protected by Cylance Smart AV in an attempt to breach it.įor those of you who haven’t heard about Cylance, do not be dismayed. Without any further ado, let’s begin our analysis of an attack. I do not condone any illegal activities by people with malicious intent involving the knowledge gathered from this blog post.In other words, this bypass should still be valid. While it can’t be categorised as a vulnerability, it was reported to Cylance beforehand to which they replied that it was out-of-scope for Cylance SmartAV to detect and block such advanced attacks.We’ll discuss this later on in this post but for now, fellow readers be forewarned.
