Say hello to BadUSB 2.0: USB man-in-the-middle attack proof-of-concept

Oh peachy, say hello to BadUSB 2.0, a tool “capable of compromising USB fixed-line communications through an active man-in-the-middle attack. It is able to achieve the same results as hardware keyloggers, keyboard emulation, and BadUSB hardware implants. Furthermore, BadUSB2 introduces new techniques to defeat keyboard-based one-time-password systems, automatically replay user credentials, as well as acquiring an interactive command shell over USB.”

The full research paper, BadUSB 2.0: USB man-in-the-middle attacks” (pdf), by security researcher David Kierznowski, is available on Royal Holloway. The paper describes BadUSB2 as an “in-line hardware solution” which is “capable of performing passive or active man-in-the-middle attacks against low-speed, USB-HID devices, such as keyboards and mice.” Yes, BadUSB2 can “intercept messages going to the host, as well as messages destined for the peripheral.” Its attack capabilities are impressive.
