Bad USB

A Bad USB refers to a type of attack or a malicious USB device that exploits vulnerabilities in a computer system. It takes advantage of the inherent trust placed in USB devices to execute unauthorized actions or malicious activities.

A Bad USB can be in the form of a modified USB flash drive or any other USB device, such as a keyboard, mouse, or even a charging cable. The device is designed to appear normal and legitimate, but it contains a hidden payload or malicious code that gets executed when connected to a target system.

Once connected, the Bad USB can perform various malicious actions, including keystroke logging, launching malware, stealing sensitive information, or even taking control of the entire system. The attack vector used by a Bad USB often takes advantage of the inherent functionality of USB devices, such as their ability to act as a Human Interface Device (HID) or a mass storage device.
