Programmable HID USB Keystroke Dongle: Using the Teensy as a Pen Testing Device

Presented at DEF CON 18 (2010), July 31, 2010, 7 p.m. (50 minutes)

The Programmable HID USB Keystroke Dongle (PHUKD) is a small device based around the Teensy microcontroller development board. It allows users to program in keystrokes and mouse macros that can execute when the device is plugged in, after a set time, or when certain environmental conditions are met (light, noise, temperature, etc.) This device can be used as a replacement for a U3 hacksaw, as a device left behind to execute commands when someone with elevated privileges is likely to be logged in, or give as a Trojan device to unsuspecting targets. Much pwnage should ensue.
