Hi. I created an unpackme using VMProtect 2.13.5. The only task is to devirtualize the blocks of code that are virtualized. There are 7 short functions. Each will execute when keyboard numbers 1-7 are pressed. The functions are virtualized as follows: 1 - Only mutation with no additional options 2 - Virtualization with no additional options 3 - Virtualization with the VM integrity check option 4 - Virtualization with the register scrambling on VM exit option 5 - Virtualization with the hide constants option 6 - Virtualization with all 3 extra options 7 - Ultra mode (which means mutation + virtualization) with all 3 extra options The pu…

[ Solutions so far: JohnWho, What ] (read whole thread) Hello folks. Decided I would post this here as well, as we're lacking some exercise on these kinds of targets. Purpose: open up the test target, click OK on the message box. Use any tool you want to alter a byte in application's active memory (e.g.: "MZ" string at ImageBase) and another message will appear. Goal: make the 'bad' message never pop-up, but not through patching the all-too-clear JUMP. Inline VMProtect's CRC check method so the CALL always returns 1. Again, not through MOV EAX,1|RETN (P.S.: imagine you don't know where this function is in a well-obfuscated target). …
