Red Teamer, Malware Developer, Security Researcher

About Me


I think like an attacker.

I push the limits of your security infrastructure, then rebuild it stronger.

Send me a message. Let's grab some coffee and swap stories.

    Cyber Security News Article

    Feb 2024 - May

    Created a sophisticated, covert Windows-based credential dumper using C++ and Microsoft Macro Assembly x64.


    Historically has (and may presently still) bypassed Windows Defender and commercial security solutions Malwarebytes Anti-Malware and CrowdStrike Falcon EDR Complete.


    Avoids detection by manually implementing NTAPI operations through indirect system calls, disabling telemetry, obfuscating API function names and pointers, creating offline copies of the LSASS process to perform memory dumps on, and corrupting the signature of dropped files.


    Project has gained >300 stars from other members of the red teaming community on GitHub since initial release.

  • etwunhook

    Jan 2024 - Feb 2024

    Created a Windows-based ETW unhook PoC using C++ and Microsoft Macro Assembly x64. Overwrites NtTraceEvent opcode by performing indirect system calls with NtProtectVirtualMemory and NtWriteVirtualMemory and ultimately disabling ETW at Nt* function level.


    Avoids detection by bypassing EDR hooks on the Windows API with manual implementation of Nt* functions and finding unhooked opcodes to use as trampolines.
