SAT, SMT, and CTF, oh my!

Presented at ToorCon San Diego 18 (2016), Oct. 15, 2016, 3 p.m. (50 minutes)

This talk will give an introduction to SAT solvers, SMT solvers, and their applicability to security CTF challenges. Real challenges from recent CTFs will be used to show how these tools can sometimes be used to find flags automagically. Finally, cutting-edge applications of SAT/SMT solvers such as shellcode and ROP chain generation and concolic execution will be touched upon.
