Samy Kamkar is an engineer who takes time demonstrating how small conventional devices can have much more danger than usual. Its latest creation is PoisonTap, software that converts the small Raspberry Pi Zero in a lethal device for the safety of our laptops.
This tool achieves that by connecting the RPI Zero to any USB port of a computer all web traffic unencrypted intercepts, including authentication cookies that are used to log in all types of private accounts, and that information is then sent to a Server that is under the control of the attacker.
