Re: inline meterpreter payload

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:

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

Assuming this is for X86 arch, you have to make sure that the EDI
register contains your socket descriptor (the value of the ConnectSocket
variable). You can do this via inline asm, but it might be easier to
just prepend the 5 bytes for setting it to your shellcode:

BF 78 56 34 12           mov edi, 0x12345678

For 64 bit, you have to use the RDI register (and need 10 bytes):

48 BF 78 56 34 12 00 00 00 00     mov rdi, 0x12345678


Hope this helps,


Michael

PS: This is the reason why the calling convention within Metasploit is
called "sockedi" :-)
