Our talk addresses the challenges faced by reverse engineers in navigating and exploring large, unknown binaries. We introduce a range of efficient, architecture-agnostic heuristics to quickly detect intriguing code locations in real-world applications. This ranges from the detection of cryptographic algorithms and complex state machines in firmware to string decryption routines in malware. Then, we use these techniques to identify API functions in statically-linked executables and pinpoint obfuscated code in commercial applications. Attendees will gain valuable insights and tools to enhance their reverse engineering workflows and discover new code detection strategies applicable to a wide array of scenarios.
