Robot can rip the data out of RAM chips with chilling technology
"A lot of times in the bootloader, you're gonna see decryption keys. You're also going to see the bootloader code – which a lot of times, if you have encrypted firmware on flash, and you have a boot ROM that's secure even somewhat, you can have a really hard time even getting access to read the code. But with this approach, you get the code, you get all the data, you get the stack, you get the heap, you get all the physical memory," he recounted.
"But if you look at embedded devices, they don't have modular RAM," said Cui."It's all soldered on. We also worked on a number of very custom memory controllers. We used this approach to do the"So once we got one memory chip pulling off reliably and then reading correctly, we had to do not one but five chips, because they're all interlaced together. And then three of the chips are on one side of the board, and two of them are on the bottom of the board.
