## Summary

Joe Grand, a hardware hacker and engineer, discusses his recent work reverse engineering a Trezor cryptocurrency wallet to recover $2M, detailing the fault injection and glitching techniques used to extract private keys from STM32 microcontrollers. He reflects on his career, including the design of the JTAGulator and DEF CON badges, and explains how burnout and the pandemic led him to prioritize mental health, meditation, and selective, fun projects like the Pizza Compass. Grand emphasizes the importance of open-source security tools in helping engineers build more secure products and advocates for a community-focused approach to hardware hacking.
