Black Hat USA 2011: ToolsTube with Byoungyoung Lee on DarunGrim

DarunGrim is a free binary diffing tool. Binary diffing is a powerful technique to reverse-engineer patches released by software vendors like Microsoft. Especially by analyzing security patches you can dig into the details of the vulnerabilities it’s fixing. You can use that information to learn what causes software break. Also that information can help you write some protection codes for those specific vulnerabilities. It’s also used to write 1-day exploits by malware writers or security researchers.

Byoungyoung Lee is currently M.S. student at POSTECH. He is a sub-developer of DarunGrim and he has interests in both practical and academic software security research. In the past, he actively participated wargames and advanced to the DEFCON CTF final round two times. He also published fuzzers and exploits targeting Microsoft products. His academic research interests are in binary obfuscation and location privacy, which were published in ACM SIGKDD and ACM ASIACCS. From Fall 2011, he will join a CS Ph.D. program at Georgia Tech.
