Workshop: Hands-on binary (de)obfuscation // Arnau Gàmez i Montolio

This workshop introduces modern binary (de)obfuscation. After a brief lecture on key concepts, we’ll walk through practical examples, using symbolic execution to extract and simplify obfuscated expressions. Finally, we’ll apply program synthesis to recover the semantics of obfuscated code.

KEYNOTE: Security products don’t have to suck // Haroon Meer

It has been 15 years since FX famously quipped that by quality level, we are better off defending our networks with Microsoft Word than a Checkpoint firewall. Security products are still pretty terrible - but why? This keynote examines why this keeps happening and plots a path to a different world.
