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). …

View File VMProtectDDK v3.84 x64 No.2 2024 If you want to try this challenge, please read the following text descriptions: 1.

View File CrackMe with Anti Patch The program uses VMP protection, and calls the relevant checksum SDK, even if the violent crack may also be slightly more complex, here provides a baymax patch tool to achieve the crack program, interested friends can read the pdf tutorial. The function of the program to determine whether the input is correct or not does not use the SDK for protection, and verify the error dialog box strings are searchable, but these do not mean that it is easy to crack, because the code also calls the memory checksum, determine whether the debugging and other SDK interfaces. So how to realize the cracking of this crac…
