Learn to extract and reverse engineer ROM contents through advanced disassembly techniques in this conference talk from Recon 2025. Discover how to photograph chip dies and identify row and column lines to extract bits in physical order from mask-programmed ROMs. Explore the development of specialized disassemblers that grade for correctness to determine proper bit ordering when converting physical bits to logical bytes. Master architecture-specific tricks for both CISC and RISC processors that enable successful ROM recovery and reverse engineering. Gain insights into cutting-edge methodologies for hardware security research and firmware extraction from presenter Travis Goodspeed's recent work in this specialized field.
