Vishwanath Akuthota, a 2017 MBA graduate of the College of Saint Rose in Albany returned to the school this February to bring his vengance to the school's computers (archived). Akuthota used a commercially available USB Killer device to fuck some shit up as he filmed himself using the device. The device took the 5 volt USB power output to charge its reserves and then delivered a -220 volt discharge, repeatedly. This attack vector works on any device too lazily and cheaply engineered to include surge protection for both positive and negative voltages built into the USB ports.

Akuthota is allege to have caused ~60,000 USD in damage.
