We considered ourselves to be a powerful culture capable of creating secure devices
This place is not a place of cryptographic security
No keys are secure here
The method of compromise here was honestly absolutely batshit
This disclosure is a warning about holy fuck did you see what they did
The danger is in a particular location by the power LED
… it increases towards the center of the CPU
… the center of the danger is in the cryptographic libraries
