DIY USB Killer?
I am fully aware of the legal consequences of property damage and in no way do I endorse it. I am curious however about the technology behind the attack method of the USB KIller http://www.usbkill.com. On their product page there is a picture of the device without it's cover and it appears to be mostly an array of capacitors. My current guess is that when plugged into the target device the capacitors are charged and once the array reaches a certain voltage it is shorted across the data terminals.
I was wondering if anyone had bought one and could confirm this or if anyone had any alternative ideas about its operation.
