In the future, static analysis catches hookers before they have a chance to act.
We present PreVice, a static analyzer that very quickly detects a variety of hooking capabilities--including Detours, import, and syscall hooking--in x86 and x64 Windows PEs. We discuss the inner workings of the static analyzer in theory and practice, and then we delve into some of the interesting things we found during a scan of many, many millions of files.

Andy Wortman
Andy Wortman is currently focused on static analysis of compiled code, abstracting interesting aspects back to something amenable to machine (or human!) understanding. Andy has worked on disassemblers, decompilers, and static analysis at Cylance to advance its capabilities in program analysis and extracting program behavior. Aside from program analysis work, Andy is a fan of programming language theory, virtual machine and interpreter construction, ham radio, and astrophotography, and is always excited to talk about weird computers.
