View File Example CrackMe - Debug Blocker x64 This is an example for submitting a CrackMe in the Downloads section of the site. You can download the file and run Debug Blocker x64.

View File BinaryShield (Custom VM) This is my first attempt at a binary protector. Currently, the VM has very little protection, so this should be good for those interested in learning about VM-based obfuscation. I intend on uploading new challenges that feature my protector as I add more features. BinaryShield source code: https://github.com/connorjaydunn/BinaryShield GOAL: - You must find the correct key. Simply patching to get a goodboy message is NOT allowed. - Bonus points for devirt and explanation of your approach. - MOST IMPORTANTLY, have fun! …

[InlineMe] VMProtect IsValidImageCRC() 1 2 3

- 46.8k views
[ 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 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…
