Challenge of Reverse Engineering

View File Python Patchme (Custom VM) Hello, Since the use of vm's is quite popular in .net obfuscation I thought it would be interesting to make one in Python.

This is purely experimental to see if it would be useful somehow. I also used my own protector that adds cflow, so expect to see a lot of jumps.

Difficulty: 3 Language: PureBASIC Platform: Windows 32bit OS Version: XP/Vista/7/8/8.1/10 Packer/Protector: ASProtect 32 2.78 Description: This is considered the easiest protector to unpack with a VM. I only seen 2.5x unpackmes around the net and most of the links were dead, so I made a new one. One binary has just protections, and the other also has license features minus hardware-lock. I couldn't get the API file to generate HWID and use SDK for it and didn't want to try and keygen a HWID. License version has keygen and password features.
