Extracting an ELF From an ESP32

Explore the process of extracting an ELF file from an ESP32 flash dump in this informative conference talk from Shmoocon 2020. Delve into the intricacies of the Espressif ESP32 system on a chip (SoC) and its applications in mobile devices, wearable electronics, and IoT. Learn about the challenges faced during reverse engineering of ESP32 firmware images and the development of custom tooling to overcome these obstacles. Gain detailed insights into the binary format of ESP32 firmware images and the step-by-step process of converting them to ELF files. By the end of the talk, acquire the knowledge to progress from a flash dump to creating a control flow graph in IDA. Presented by Chris Lyne and Nick Miles, experienced security researchers from Tenable, this 43-minute presentation offers valuable information for those interested in embedded systems security and reverse engineering techniques.
