Actually, I had just woken up from sleeping ~8 hours about 3-4 hours before the question was released, and we didn't do any of the exploitation of networked services except Pwtent Pwnables 200 (compiled Python) and Binary L33tness 100 and 200 (trivial patches in a debugger). I was tired by the time the rest came out, and the other reversers on the team burned themselves out on the PP400 (the PPC question) and Binary L33tness 300 (a huge red herring that actually printed the answer, encoded in hex when it was run). Thanks for defending me, though.
