Glitching For n00bs (#6499) (31x16)

Air date: Dec 27, 2014

Despite claims of its obsolescence, electrical glitching can be a viable attack vector against some ICs. This presentation chronicles a quest to learn what types of electrical transients can be introduced into an integrated circuit to cause a variety of circuit faults advantageous to an reverser. Several hardware platforms were constructed during the quest to aid in research, including old-skool & solderless breadboards, photo-etched & professional PCBs, FPGAs, and cheap & dirty homemade logic analyzers. The strengths and weaknesses of the various approaches will be discussed.
