Title: Source Engine code auditing adventure


In this talk I will talk about the Source Engine, the leaked codebase and how I audited it to find vulnerabilities. This also acts as a case study on how real life code bases are audited.


The participants should have basic knowledge on C/C++, basic knowledge on x86 memory exploitation techniques, and how exploit mitigations (NX, ASLR, Stack Canaries) work.

Speaker Bio

I’m Bien Pham, an offensive security engineer from the Sea Security Team. I’m known for finding vulnerabilities in Valve Corporation’s games, for instance, the Counter-Strike series. I also play CTFs, mostly handling pwn challenges.
