This workshop will be using Arduino IDE to flash the proper program to each microcontroller. It can be downloaded for your operating system from arduino.cc. You will also need a device with Wi-Fi access. With two inexpensive microcontrollers, anyone can program and build a Wi-Fi connected keystroke injection tool (the Wi-Fi duck!) that, when plugged into a target computer, can allow a hacker to control it (using a graphic user interface) remotely from up to a mile away. This workshop is for beginners interested in hacking with microcontrollers, hackers interested in learning keystroke injection attacks, and anyone interested in what's possible with low-cost devices and Arduino IDE.
