022 - Bits Through the Microscope
Chris Gerlinksy, a reverse engineering consultant from PDR North, explains how he extracts ROM data from microcontrollers by deprocessing chips and imaging them under a microscope. He details the evolution of security in PayTV smart cards, from simple 8-bit chips to modern devices with anti-tamper shields and implant ROMs that require specialized etching to reveal data. Gerlinksy also discusses the tools of the trade, including wet etching, CMP polishing, and micro-probing stations, as well as software for automating bit extraction from optical images.
