EXE injection plus

Posted by scriptjunkie in Metasploit on March 26, 2010

For those interested in metasploit (or whatever) payload injection into EXE files, the metasploit patch (now posted http://www.metasploit.com/redmine/projects/framework/repository/revisions/8896) is based on one case, albeit the most likely to work, of my original program in C and Win32 API. This original program also can embed the payload if it fits into unused space at the end of a code section, which […]

Metasploit EXE code injection

Posted by scriptjunkie in Metasploit on March 22, 2010

There is no gain to most strict password policies over […]

Shellcode API hashes

Posted by scriptjunkie in Metasploit on March 5, 2010

For all you shellcoders out there; to make Windows API calling easier, you can use Stephen Fewer’s block_api.asm in the Metasploit tree. http://www.metasploit.com/redmine/projects/framework/repository/revisions/8160/entry/external/source/shellcode/windows/x86/src/block/block_api.asm But you need the function hashes, which if you don’t have the DLL on your current OS, or the python file, or something like that can be annoying. So I posted a […]
