my prediction before reading is that they're using the piezo sparker to beat the DUT over the head with a big EMF spike

Edit: Nailed it!

I thought they were going to just heat a chip to increase the overall error rate

		Be it eletric or thermal, i came here for fried hardware and left disappointed. Now i have to wrangle my curiosity to what happens when you lighter-spark a usb port for the rest of the day.

Yeah but the devil is in the details ;)

It's not like you can randomly spike stuff and achieve an exploit
