For around $50, you can purchase the USB Kill Stick, a USB stick that destroys almost anything that it’s plugged into. Yes you read that right, anything.
How does the USB Kill Stick work?
Well, when the USB Kill Stick is plugged in, it rapidly charges its capacitors from the USB power supply, and then discharges. All of this happens within seconds. Any unprotected equipment will ‘instantly and permanently disable unprotected hardware’.
This devastating device was created to illustrate that any public USB port is a threat to any sort of cyber attack, and now electrical attacks.
