Glitching a microcontroller is pretty trivial these days. You remove the caps and short the power supply for a short period when the debug register is read. Obviously you need to glitch the supply at the right exact time, hence many people use another microcontroller controlling a mosfet that shorts the supply programmatically.
NRF52s had this issue too (like many) and Nordic made new silicon revisions in 2022 (on all their products!) where they don't check for the debug register on boot (and have the protection enabled by default).
It remains to be seen if such revisions completely fix fault injection attacks though.
Started watching after your comment.. Fantastic documentary! And its great to see some shots of the screens they use to manage the probes and stuff. And yes, some ninjas cutting onions..
... I found it a bit poignant / emotional as well! ... those engineers in a dusty office beside McDonalds... quietly keeping the mission going... in touch with something that's beyond our solar system now... True engineers! No glitz... quiet dedication...
How do you know it's 600? what would be the sale price? Sometimes with a little modification, a hw product can work in multiple b2b verticals ;)
Ive done a few products myself with injection molding, production pcbs, etc. and it's amazing how different customers look at it and ask for different features.
Is this like an fMRI for a neural net? We can see which regions light up depending on various topics..
I wonder if an assessment neural net can be plugged in to evaluate the regions that light up automatically.., just like when they had an AI reconstruct what the patient was looking at, from only fMRI scans!
Anyone can recommend an IP KVM to connect to DOS machines that have 1 VGA signal, 1 component video signal (this is a secondary video signal from an old camera on this machine), DIN keyboard connector and RS232 mouse? So far PiKVM looks like the best candidate.
