Explore the intricacies of automatic exploit generation in binary programs through this IEEE Symposium on Security & Privacy presentation. Delve into the innovative Mayhem system, designed to uncover exploitable bugs and generate working shell-spawning exploits in executable programs without debugging information. Learn about two groundbreaking techniques: hybrid symbolic execution and index-based memory modeling, which address challenges in managing execution paths and reasoning about symbolic memory indices. Discover how Mayhem successfully identified 29 exploitable vulnerabilities across Linux and Windows programs, including two previously undocumented issues. Gain insights into the system's architecture, symbolic execution process, safety policies, and optimization techniques for efficient vulnerability detection and exploit generation in binary code.
