This talk will demystify the process of writing a rootkit, moving past theory and instead walking the audience through the process of going from a driver that says “”Hello World”” to a driver that abuses never-before-seen hooking methods to control the user-mode network stack. Analysis includes common patterns seen in malware and the drawbacks that come with malware in kernel-mode rather than user-mode.

We’ll walk through writing a rootkit from scratch, discussing how to load a rootkit, how to communicate with a rootkit, and how to hide a rootkit. With every method, we’ll look into the drawbacks ranging from usability to detection vectors. The best part? We’ll do this all under the radar, evading PatchGuard and anti-virus.
