The author is genass3 and the executable is written for Windows. The authors description: The diff between other versions: - Rewrited pass verification algorithm (removed the hash algorithm) - Improved string encryption - Rewrited some obfuscation things (make it easier) Your main goal is to find the password, for every user password will be different. I enjoyed the authors previous patchme  so I'm really looking forward to tackling this revamped version. Just like their previous patchme, this is implemented as a console application. It was created using Microsoft Visual Studio 2022. The binary does not appear to be packed. Taking a look at the strings, we see some familiar func...

The author is genass3 and the executable is written for Windows. The authors description: Try to patch, should be not so hard, also you can find password very easily, if you have eyes :) Ur main goal is patch. Also feel free to give a feed back about the protection, i would like to read and improve. The source code of the protection - https://github.com/generin0/PatchGuard The source code of the crackme - https://github.com/generin0/crackme1 I think we should normalize including the source code to crackme challenges. For one, it would make it easier to know whether they're malicious or not. Two, it makes for a great learning aid. The old adage to learning reverse engineering was "wr...
