USBNinja is an information security and penetration testing tool that looks and functions just like a regular USB cable (both power and data) until a wireless remote control triggers it to deliver your choice of attack payload to the host machine. In essence, USBNinja is the next step in the evolution of BadUSB, embedding the attack in the USB cable itself.
The Attack
When plugged into a host computer, USBNinja acts just like a regular USB cable. For example, it can be used both to charge your phone and to transfer images from your phone to your computer. However, perfectly concealed within USBNinja is a very small Bluetooth device, patiently waiting. When USBNinja receives the secret command, either from a smartphone running the USBNinja app or from our custom-built Bluetooth remote control, it goes from a passive cable to a stealthy attacker by emulating a USB mouse and/or keyboard to deliver its hidden payload to the host computer.
The Payload
The payload delivered by USBNinja is completely customizable. You can use the standard Arduino IDE to create your own payload and we’ll also provide plenty of examples of payloads that inject keystrokes and move and click the mouse.
Use Cases
USBNinja is truly a versatile tool, with applications such as practical jokes, magic tricks, secret love confessions, game assists, and information security trainings. We leave it as an exercise to the reader to come up with their own uses.
