James Chambers
James Chambers is a Senior Security Consultant in the NCC Group Hardware & Embedded Systems security practice. He enjoys reverse engineering video games to find opportunities for creative code execution, as well as resurrecting lost features. His past projects include reverse engineering Animal Crossing to discover an unused NES ROM loading feature that could also be used to patch code in memory, fuzzing GameCube games in emulation using Dolphin, and programming a Proxmark to fuzz Amiibo data over NFC.
Sessions
The PowerG protocol for wireless security systems is proprietary and has no public specification or tooling for analysis. We will present our work on reverse engineering PowerG to understand the protocol, assess its security claims, and identify protocol-level issues. We will also release tooling for capturing PowerG packets with SDRs such as the HackRF, as well as decrypting and analyzing PowerG packets.
