    [ 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). …

    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 crackme? Baymax Patch App Protected by…

    NanoButton A follow up of TinyCrackMe Challenge: - Press the button "Hi" - If correctly bypass, a MessageBox with `:3` show up. Rules: 1. Patch? Here's a deal: - No patching if you're unpacked UPX, as final result! - Allowed patching if you're not unpacked UPX, as final result! - only patch-fix the flaw like missing stdc dll, or temporary byte patch to making loader or hook 2. Spoiling? Yes! (originally in crackmes.one is "no") 3. Keygen? useless. Because the goal is bypass it! 4. Hooking? Allowed! It's not a patch! 5. Loader? Allowed! It's just a mem patch, not file patch... 6. Any these above, do not use any tool to create stuff like B…

    Python Patchme (Custom VM) (UPDATED v1.2) Hello, Since the use of vm's is quite popular in .net obfuscation I thought it would be interesting to make one in Python. Hereby I release my first crackme using my VM. It's a very simple VM so it shouldn't be that hard to reverse with the right knowledge. 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. Goal: Patch it (ultimately devirtualize it, but that's not necessary) EDIT: This is now updated. I tried to make sure it isn't possible to patch with 1 or 2 jumps. File Information …
