Stripe Capture the Flag

[John Collison <john () collison ie>]

Hi,

We built a wargame around web security vulnerabilities. The nine
levels are built atop fairly standard web software stacks, with
increasingly tricky exploits required, and a special-edition t-shirt
at the end. It's as much for fun and education as anything else. Would
love to have you play!
