Simple crackme I wrote, only 36 lines. I wanted to test and see if people would be able to actually pull this off, you won't get far with only static analysis. So I suggest you xref, bp, and debug, then look at RCX on some specific function calls, that'll get you the key you need.

You can either get the key and login, or you can actually patch the program and jmp to success.

 

This program is not packed at all, you can open it up in IDA without the need to dump.

@H0NDA_ lol wtf runs fine for me lemme make sure it wasn't a debugging issue

 

Edit: I'm not sure what could be causing a crash, none of the mutated code should be running so it SHOULD function properly.

Just in case I had a friend test, he ran on KVM and Wine and said it worked well for him
