ChaffCTF is a small, Jeopardy-style CTF intended to test how effective chaff bugs are at making binary exploitation more difficult. There will be six challenges of roughly equal difficulty, and each team will get three chaffed and three unchaffed challenges, chosen at random.

Chaff bugs are non-exploitable bugs added to a program to increase the difficulty of finding exploitable vulnerabilities. You can find out more about them by reading our paper (https://arxiv.org/abs/1808.00659) or checking out some of the news coverage (https://www.vice.com/en/article/43p7dm/software-chaff-bugs-could-make-it-more-secure).
