• Exploiting Undocumented Hardware Blocks in the LPC55S69

More about LPC55S6x and their LPC55Sxx Secure Boot

Ghidra is a software reverse engineering framework… and it is one of the NSA's github repositories.

Laura will also be speaking about this at Hardwear.io in early June 2022 in Santa Clara.
