Dangerous games, binary obfuscation and how not to shoot yourself in the foot while reversing ransomware

Obfuscation is the deliberate act of introducing anomalies in a binary, source or machine instructions in order to deter analysis and effectively "harden" the binary. In this talk, the speaker will attempt to introduce the concept of obfuscation with a focus on ELF & PE binaries to demonstrate the effectiveness of such techniques in deterring analysis and throwing the analyst on a wild goose chase. We'll cover a range of techniques, how and why they work, and how do different analysis tools react to those changes. Basic knowledge of computing is required for this talk.
