Sneaking Past Device Guard

Explore advanced techniques for bypassing Device Guard (WDAC) in Windows 10 systems in this Hack In The Box Security Conference talk. Dive into rarely discussed and novel methods that allow running unsigned code, even with application whitelisting enabled. Learn about approaches requiring admin access, those leveraging Microsoft Office without user interaction, and a low-privilege technique using only native OS executables. Examine the feature's implementation across different contexts, and delve into the internals of Windows scripting engines and their host processes. Understand how popular bypass techniques work, including those presented in the talk. Gain insights into the scope of the problem, potential security implications, and suggestions for future feature development. This comprehensive exploration of Device Guard vulnerabilities provides valuable knowledge for security professionals and researchers interested in Windows system security.
