LazyHook is a stealthy API hooking framework that bypasses Host Intrusion Prevention Systems (HIPS) through call stack spoofing. By leveraging CPU-level hardware breakpoints and Vectored Exception Handling, it executes arbitrary code as if it originated from trusted, Microsoft-signed modules—completely fooling behavioral analysis engines that rely on call stack inspection and module origin verification.

Evade behavioral analysis by executing malicious code within trusted Microsoft call stacks
Uses hardware breakpoints + VEH to hijack legitimate functions and spoof module origins

CLR Unhooking Tool
Note: For this to have the effect of a clean CLR, you’d need to manually map the DLL from disk into memory. You cannot use LoadLibraryA/W, because antivirus solutions will detect the DLL load event and may hook it immediately. If you want this behavior, you can look up existing manual mappers on GitHub and integrate one into your codebase. I’m not including one here, as AV vendors generally don’t appreciate that
A native C++ utility that bypasses EDR/AV hooks in the .NET Common Language Runtime by restoring the original nLoadImage function implementation.
