PoisonTap, as the tool has been dubbed, runs freely available software on a $5/£4 Raspberry Pi Zero device . Once the payment card-sized computer is plugged into a computer’s USB slot, it intercepts all unencrypted Web traffic, including any authentication cookies used to log in to private accounts. PoisonTap then sends that data to a server under the attacker’s control. The hack also installs a backdoor that makes the owner’s Web browser and local network remotely controllable by the attacker.

While inspiring for their creativity and elegance, Kamkar’s inventions also underscore the security and privacy tradeoffs that arise from an increasingly computerized world. PoisonTap continues this cautionary theme by challenging the practice of password-protecting an unattended computer rather than shutting it off or, a safer bet still, toting it to the restroom or lunch room.
