Challenge of Reverse Engineering

A very basic crackme I coded a few days ago, the purpose is to get yourself acquainted with the x64 intrinsics. Rules are basic too just fully reverse the damn thing and the first 2 people will get the crackmes source code. Happy Reversing EDIT: The second attachment contains the crackme with the MSVC libraries linked statically.

Hello, this is my first CrackMe, but I think is very hard because I haven't seen this method yet. Sorry for 2mb file, but linking is very much size. There is a function which returns true/false for Login, patch it to true and you did it. Might be super easy or super hard, idk! Good luck CrackMe.zip

When it gets broken I'll post the orig. credits + source + custom mods + toolsThere's some stupid stuff in there, not trying to be fancy/complicated.

Protect : Confuser 1.1 Express Edition CrackMe.rar

Hi. I made some UnpackMe styled executables protected by the latest demo version of CodeVirtualizer (2.0.8.0). Each executable contains one function virtualized by a different virtual machine setting. The different virtual machines used are: - FISH32 Black - TIGER32 Black - PUMA32 Black - SHARK32 Black The virtualized functions are very short, approximately 20 asm instructions. No other protections are used. The virtualized function will execute when F1 is pressed. codevirtualizer_2.0.8.0_demo_devirtualizeme.rar
