There is an infection that encrypts peoples files, and when you pay them you get a decrypter than decrypts them. I have disassembled this to the point to where i have the function that decrypts in C# now, and even made a flow diagram of how the encryption works. But i need someone to be able to disassemble it more, to get enough information, and then crack the custom encryption. I know its crackable, as it is XOR. But they customized it to use it in a CFB kind of way. If you know CryptoGraphy, and assembly, Please contact me.
Also, the Decrypter exe is highly obfuscated with a custom obfusctor. So it does take time to figure out which functions are junk and which are real.
