This was shortly after the initial release of…

Follow Up on DEP and AV Bypass
This is a continuation of research based on my adventures on a penetration testing engagement described here. There were a few key features that I really wanted to add to enhance my DEP/AV bypass tool: Bypass a majority of AV systems Remove the dependency on the msvcr100d.dll file Combine the Metasploit payload in the shellcodeexec…
