ever wondered what a hack/bot is writing to memory to make certain actions happen? I found this awesome little tool called "WriteProcessMemory Monitor" (NoVirusThanks) which will monitor WriteProcessMemory and write down every call to it.
I made a little video to demonstrate the tool:
As you can see I use Cheat Engine to write a guid to the targetGuid address. Later I converted the byte array WriteProcessMemory Monitor logged back to an UInt64.
