CTF quals 2010 writeups from n0tl33t

These are writeups for problems from the 2010 DEFCON CTF quals. I played for n0tl33t, a team I put together consisting of several smart people I know from Michigan, a former Microsoft intern friend, and some of her associates (actual names forthcoming when I get around to asking folks if they want to be listed). We finished 31st with 4100 points. Full scores on ddtek's site, plotted at the bottom of the page.
