Last year I contributed to the Bsides Algiers 2013 event, I was
in charge of
the final CTF challenge design. The challenge had a wargame format which was based of two wired servers Unix Solaris and Debian. The scenario covered WEB & infrastructure vulnerabilities
and was based on a real world cases. The flags were inserted in a way to
guide the challengers to follow the best path to achieve the end goal
and gain the "root" access.
This video contains the walkthrough from my perspective. In one of my following statements I also will post a written summary which will explain the whole scenario.
