They get into how a kid with an Atari 400 ended up in the hacker underground, why the hacker mindset can't be taught, and what 23 years as an independent hacker really looks like. Joe Grand walks through learning fault injection to free a locked wallet, how he and his colleague found an attack on STM32 chips that happens before the boot ROM even runs, why a vendor that won't respin silicon leaves chips vulnerable forever, and why "they need physical access" is not a security strategy (see: the San Francisco parking meter he bought on eBay). Plus failure, burnout, full disclosure, and his new travel show exploring hacker culture around the world.
