Behemoth0 - behemoth1

behemoth0 was a simple password authentication challenge with a program that had a hardcoded password. This one could be solved simply by using ltrace. By running that we were able to see a call to strcmp() where it compared our value to the value "eatmyshorts". If you provided it that password it would drop you into a shell as behemoth1.
