After more than 10 years I decided to write a new Crackme challenge. The binary contains some tricks, with some revivals from old sk00l era :) If you find it interesting and you want to write a tutorial, I'll be happy to add the link to your tutorial in this page. Enjoy!
If you think to have find a bug, please open an issue or send me a DM on twitter: https://twitter.com/s4tan
The program runs only on 64-bit systems
Difficulty: Hard
You can download the binary from: https://github.com/enkomio/s4tanic0d3/releases/tag/1.0
