[unpackme] Xheo Codeveil Unpackme

Recommended Posts

I?ve to say that I?ve no idea what to unpack here. I?ve bypassed the layers and a CALL EAX I think went to "OEP" or better said a call to a .NET function that executes the app....

Is this done then?

Its a .net app so the unpacked copy should be loadable in .NET Reflector or any other .net decompiler,

and ofcource the file needs to be fully runnable :)

Send me ur unpacked copy when ur done ;)

hi LibX,

I?ve reached OEP but my dump always refuses to run. I believe that I?ve fixed the Header correctly but it that this was not enough :(

Could you please help me unpacking this file?

Same here, finding OEP is very easy, for a short version just BP the Jump Dword right above the Entrypoint ;)

Anyway, I dumped and then fixed the header so at least it starts.

It immediately crashes with some .NET error message, bla bla...

I dont belive unpacking .NET is that easy, there are some tricks for sure, like magled meta data, dunno :/ Never unpacked .NET apps except for NsPack and even there I used one of the automatic .NET generic unpackers (which works pretty fine most of the time)...

You wouldnt have posted it if it was that easy, huh ? ;)

Hehe I was lazy. Hex editor in your hands, and warm your seat up a bit, and you can code a xor packer in a day. Amazing that companies sell them for 2k.

I dont think LibX actually coded this himself ? Or did he ? :o

He coded the unpackme, but not the packer...

Anyway, if you dont mind you could share your source w/ the forum members, might help somebody...

No must, though... if you want to keep things private ;)

Its not that hard if u take a little time to look closer at the stub ;)

And no i didn't code this packer myself :P thank god :P

Hmm looked at the tutorial again. It only shows you how to get a dump, but not how to decrypt the MSIL, so the dump is non-functioning :|
