    The best solutions will win free entrance to "Malware Analysis: Methods and Techniques" training, which will take place during Ekoparty 2011 (http://www.ekoparty.org/) Requirements for the solution: Explain how the crackme itself works, not the validation algorithm [5 points] Find the serial for the username "ekoparty" [1 point] Make a keygen, preferrably in a high-level language like Python [3 points] Make a loader or patch to accept any serial [1 points] - Optional More information and download: http://blogs.eset-la...-ekoparty-2011/ Disclaimer - I am in no way affiliated with ESET.

    Well, it's been a while since I've been in the crackmes.de scene, so I decided to come back with yet another crackme. This one is just a tad bit harder (besides, everyone loves games).

Rules: (*) No Brute-Forcing (*) No Patching (*) When solved, please submit a tutorial and valid keygen For tutorials, tools, and help on ALL RCE topics, please visit BlackStorm Reverse Engineering team at: http://portal.b-at-s.info Greetings to Kurapica, revert, Apakekdah, SRC, lena151, obnoxious and everyone else contributing to Bla…
