Tools and Exploits

New to Me

This section is for news, techniques, and tools that weren't released last week but are new to me. Perhaps you missed them too!

  • wwwgrep is a rapid search “grepping” mechanism that examines HTML elements by type and permits focused (single), multiple (file based URLs) and recursive (with respect to root domain or not) searches to be performed.
  • AppInitHook is a global user-mode hooking framework, based on AppInit_DLLs. The goal is to allow you to rapidly develop hooks to inject in an arbitrary process. Developed to reverse engineer and customize random applications, it has broad implications for read teaming.
  • ElusiveMice is a Cobalt Strike User-Defined Reflective Loader with AV/EDR Evasion in mind.
