DRM obfuscation versus auxiliary attacks

Presented at REcon 2014, June 29, 2014, 11 a.m. (60 minutes)

Code obfuscation is used in many places nowadays: - in software protection, to prevent cracking; - in DRM, to prevent piracy; - even in exploits, to prevent reverse engineering (see latest evad3rs jailbreak). We recently analyzed a widely-used DRM system, protected with some new and advanced mixed obfuscation techniques. The innovative part of our talk is that we use new classes of attacks based on auxiliary channels.
