Re: inline meterpreter payload

["Raphael Mudge - Raffi's House of Shells" <contact () fastandeasyhacking com>]

If anyone feels like playing, here's a working loader based on this guidance:

https://github.com/rsmudge/metasploit-loader

It doesn't do too bad on virustotal either:

https://www.virustotal.com/file/afe34bfe2215b048915b1d55324f1679d598a0741123bc24274d4edc6e395a8d/analysis/1347507196/

I tried connecting it to a handler for a shell payload and it died.
Any thoughts as to why? Works fine with meterpreter though.
