Thanks again for running this Stripe. It was quite fun and informative to actually implement some of these exploits rather than just recognize the possibility for it existed. Every level was instantly recognizable for the weakness that was available to take advantage of, but it sometimes took me hours of effort to write something that exploited it.
I am surely dreaming, but I would love to see a soup to nuts blog post series (not necessarily from Stripe) that would take me through every step, the reasoning involved, how to protect against the exploit, creating the C programs on linux, etc. Something along the lines of the multi-part pokerbot series I remember from a long while ago.<p>Thank-you to Stripe for putting CTF together!
Awesome guys. I greatly enjoyed being there for the final presentation, especially hearing all of the different ways people had solved the levels. Thanks for publishing the AMIs.
