Porter-Gaud CTF - Problem Set

Web problems (and Algo 1) were uploaded to a server using Docker in order to isolate them from each other, and were put on different network interfaces in order to give each problem a different IP address, rather than cluttering ports on one server. We used the Facebook Platform to host the scoreboard

Halfway through the competition, a server (10.10.1.77) was added to the scope with no description, but a corresponding flag in "Libya." The server was loaded with an unpatched version of Windows XP vulnerable to MS08-067, exploitable with this Metasploit module.
