DEF CON 23 – Chris Domas – Repsych: Psychological Warfare in Reverse Engineering
Your precious 0-day? That meticulously crafted exploit? The perfect foothold? At some point, they’ll be captured, dissected, and put on display. Reverse engineers. When they begin snooping through your hard work, it pays to have planned out your defense ahead of time. You can take the traditional defensive route – encryption, obfuscation, anti-debugging – or you can go on the offense, and attack the heart and soul of anyone who dare look at your perfect code. With some carefully crafted assembly, we’ll show how to break down a reverse engineer by sending them misleading, intimidating, and demoralizing messages through the control flow graphs of their favorite RE tools – turning their beloved IDA (Hopper, BinNavi, Radare, etc) into unwitting weapons for devastating psychological warfare in reverse engineering.
Chris is an embedded systems engineer and cyber security researcher, focused on innovative approaches to low level hardware and software RE and exploitation.
