Breaking Antivirus Software Joxean Koret, COSEINC 44CON, 2014 Breaking antivirus software Introduction Attacking antivirus engines Finding vulnerabilities Exploiting antivirus engines Antivirus vulnerabilities Conclusions Recommendations Antivirus Engines Common features of AV engines: Written in C/C++. Signatures based engine + heuristics. On-access scanners. Command line/GUI on-demand scanners. Support for compressed file archives. Support for packers. Support for miscellaneous file formats. Advanced common features: Packet filters and firewalls. Drivers to protect the product, anti-rootkits, etc... Anti-exploiting toolkits. Antivirus products or engines An antivirus engine is just the core, the kernel, of an antivirus product. Some antivirus engines are used by multiple products. For example, BitDefender is the most widely used antivirus kernel. It's used by so many products like QiHoo360, G-Data, eScan, F-Secure, etc... Most “big” antivirus companies have their own engine but not all. And some companies, like F-Secure, integrate 3rd party engines in their products. In general, during this talk I will refer to AV engines, to the kernels, except when specified the word “product”. Attack surface Fact: installing an application in your computer makes you a bit more vulnerable. You just increased your attack surface. If the application is local: your local attack surface increased. If the application is remote: your remote attack surface increased. If your application runs with the highest privileges, installs kernel drivers, a packet filter and tries to handle anything your computer may do... Your attack surface dramatically increased. Myths and reality Antivirus propaganda: “We make your computer safer with no performance penalty!” “We protect against unknown zero day attacks!”. -
