How can a Use After Free exploit in Ocarina of Time lead to a cute robot taking over an entire N64 to put the future (and the Triforce) in the game using only button presses? This talk dives into the technical details of how a Use After Free exploit, Arbitrary Code Execution, and multiple bootstrap stages allowed TASBot to take full control of an original, unmodified cart and console in front of a live audience during SGDQ 2022 with the help of Sauraen and Savestate, helping raise more than $228k for charity. This talk uses engaging explainer graphics courtesy of RGME to dig into how a Use After Free vulnerability can be exploited as well as a live demo showing the significant social impact of the exploit Here Together, in the past year and into the future.
