Last year, DARPA hosted the Cyber Grand Challenge, the culmination of humanity's research into autonomous detection, exploitation, and mitigation of software vulnerabilities. Imagine the CGC from the outside: huge racks of servers battling it out on stage, throwing exploit after exploit at each other while humans watch helplessly from the sidelines. But that vantage point misses the program analysis methods used, the subtle trade-offs made, and the actual capabilities of these systems. It also misses why, outside of the controlled CGC environment, most automated techniques don't quite scale to the analysis of real-world software!

This talk will provide a better perspective. On the 25th anniversary of DEFCON, we will go through these last 25 years of program analysis. We'll learn about the different disciplines of program analysis (and learn strange terms such as static, dynamic, symbolic, and abstract), understand the strength and drawbacks of each, and see if, and to what extent, they are used in the course of actual vulnerability analysis.

Did you know that every finalist system in the Cyber Grand Challenge used a combination of dynamic analysis and symbolic execution to find vulnerabilities, but used static analysis to patch them? Why is that? Did you know that, to make the contest feasible for modern program analysis techniques, the CGC enforced a drastically-simplified OS model? What does this mean for you, if you want to use program analysis while finding vulns and collecting bug bounties? Come to this talk, become an expert, and go on to contribute to the future of program analysis!
