Going Live

I posted OC to DailyDave's (Dave Aitel) maling list today, and I noticed several new users and hits on the site so I just wanted to welcome the new comers. We're very interested in feedback and any contributions you all can make, especially adding malware/analysis. I uploaded a few dissasemblies for people to comment and there are ida databases for some of the malware.

Enjoy the site!

This binary was packed with UPX. There are both packed and unpacked versions attached.


So I removed the "exploits" and "shellcode" secitons. The reason for this is that there are many sites that do this way better than we ever could.

If you want exploits or shellcodes then I would like to direct you to Metasploit

Those guys are awesome and anything cool we do in that realm will be available through them one way or another.

So now this site can focus on what it does best which is malware analysis, searching database, etc.


More on Korgo

Ok this is a massive post. For some reason my malware collector keeps picking up korgo worm binaries.

None of them will disassemble correctly as if they are packed/encoded. None of my file analyzers find anything. (peid, pescan, protection-id, etc) IDA shows that they are packed with a modified UPX2.

I have not figured out how to unpack it yet.

There are some A/V entries for this worm (its a LSASS worm)

If anyone has ideas on how to unpack this or even a good generic unpacker to donate to the cause it would be greatly appreciated.

Sony DRM Rootkit

md5sum: $sys$

This is just the executable. I'll get the other files up soon.

I have uploaded an ida database and flow graph for this as well.


I added the supporting dlls and sys files. Ill see if i can get the installer off the cd as well.

need a generic or modified UPX unpacker to analyze.
