A new web-based attack was discovered today and our users made a detailed analysis promptly and helped to clarify what’s going on there. What I’m talking about? And where’s the relation to the question in title? It is pretty simple . If you wanna become a [...]
Defense center and a piece of luck One of our users sent us a sample of rogue AV for analysis. He didn’t attach further informations and the binary was heavily obfuscated, so I decided to give it a shot inside a virtual machine.
