BadUSB Exploit: USBDriveBy

Samy posted a simple Mac OSX exploit leveraging the BadUSB vulnerability.

USBdriveby is a device you stylishly wear around your neck which can quickly and covertly install a backdoor and override DNS settings on an unlocked machine via USB in a matter of seconds. It does this by emulating a keyboard and mouse, blindly typing controlled commands, flailing the mouse pointer around and weaponizing mouse clicks.

In this project, we’ll learn how to exploit a system’s blind trust in USB devices, and learn how a $20 Teensy microcontroller can evade various security settings on a real system, open a permanent backdoor, disable a firewall, control the flow of network traffic, and all within a few seconds and permanently, even after the device has been removed.

Read the rest here.
