Nice, thanks. I had wondered whether the $250K in lab gear is something that a serious HW security lab would already have on hand, as opposed to specialized expenditure for just this attack. I mean I rode in a $250K(?) motor vehicle a few days ago (the #2 SF Muni bus towards the Marina) but I didn't have to spend a lot to ride it, since it was already deployed. Nobody had to go out and buy it.

Hah, our new ones are $1.3 million. https://www.sfmta.com/media/44081

Perhaps driven by restrictions on federal grants? https://media.api.sf.gov/documents/Briefing_Book_-_Muni_Fund...

Some cool tech. Wonder if we optioned the inductive charging system. https://www.gillig.com/buses/battery-electric/#1731934845437...

Wow. Equivalent ones built in England are around 1/3rd the price £350k = $470k.

Yeah but I bet the steering wheel is on the wrong side. ;)

I have an application on an SPC58 that I really want to know more about. But unfortunately; it’s a dual core with lockstep. So if it could be done; I think that automatically double-pluses the budget.

Don’t need lasers for that chip, it absolutely can be done with enough time and effort.

Don’t let fancy language like lock-step dissuade you from trying. The people who configured that chip also have to have done their job perfectly or it might still have a way in!

It’s two power supplies, two cores, lockstep, and an HSM they hype up… I’m pretty sure I would need two emps and a high precision rig at the minimum.
