Abstract:

Drivers have long been of interest to threat actors, whether they are exploiting vulnerable drivers or creating malicious ones. Malicious drivers are difficult to detect and successfully leveraging one can give an attacker full access to a system.

With the existence of malicious drivers, there is a need for those who can analyze identified samples. This analysis requires specific knowledge of the Windows operating system, which can be difficult to acquire. Windows drivers and the kernel can be overwhelming to learn about, as these topics are vast and highly complex. The documentation available on these subjects is daunting and difficult to navigate for newcomers, even for those with programming experience.

This initial hurdle and steep learning curve create a high barrier of entry into the subject. To many, the kernel space seems to be an arcane and hidden part of the operating system.

This presentation will be a high-level introduction into drivers, their usage by malicious actors and the Windows kernel. No previous experience of drivers is required.

Vanja Svajcer works as a Threat Researcher at Cisco Talos. Vanja enjoys tinkering with automated analysis systems, reversing binaries and analysing mobile malware. He thinks time spent scraping telemetry data to find indicators of new attacks is well worth the effort. He presented his work at conferences such as FSec, Bsides, Virus Bulletin, RSA, CARO, AVAR, BalcCon and others.
