With all of the scan codes matched to the keys they press, I was now ready to start building payloads. Watch out for this when creating payloads on your YubiKey if you don’t want it to automatically press Enter at the end. However, slowing the character rate by 60 ms caused the Enter key to be automatically pressed on sequences as short as one keypress. In my testing, the extra Enter key didn’t appear in sequences less than 23 keys long that were typed at the standard output character rate. I checked this by running the xinput command without any arguments and determined that its ID was 16 as shown in the output below.īoth the length of the key-press sequence and the YubiKey’s output speed (configurable from the Settings screen in YPT) appear to affect this behavior. Since the YubiKey is essentially a keyboard, the first thing I did to start capturing its keypresses was to identify its ID number within xinput. It’s also commonly abused as a keylogger when those systems are compromised, and I created the xinput-keylog-decoder tool for that purpose.
If you’re not familiar with xinput, it is a command-line tool that’s commonly included in many Linux distributions along with the graphical desktop environment. For this, I decided to use the Linux tool, xinput, and my xinput-keylog-decoder script to decode the output. the CTRL key), I needed a way to capture the raw keypresses generated by the YubiKey. Because typing the hex values into the Scan Codes field in YPT didn’t display any output, and because I expected many of the keys pressed in the unknown ranges to be keys that didn’t generate any printable output (e.g. Now all that was left to do was identify the keypresses generated by the hex values in each unknown range.

Then on the Static Password page, I clicked the button labeled, “Scan Code”. To test this, I started up the YPT and selected the Static Password option from the bar across the top. Since the YubiKey enters data into the computer just like a regular keyboard, I wanted to find out whether it could be used to press more interesting keys like CTRL, ALT, or the Windows key in addition to the standard letters, digits, and symbols. However, the YubiKey can also be programmed to type in a static, user-defined password instead. In its default configuration, the YubiKey will type a unique authentication token whenever it is used, and that token changes on each use. Step 2: Programming the YubiKey with a static password

Instructions for how to do so are included in the README file that comes with the source code and are easy to follow, so I won’t cover them here. If you use the Linux version as I did, you may need to build the program from the source code provided by YubiKey.

Since I didn’t use the old YubiKey for authentication after receiving the new one, I decided to see if I could turn it into something similar to a USB Rubber Ducky – a USB device that emulates a keyboard and sends a computer a series of pre-programmed keypresses when it is plugged in. A couple of years ago, I had a YubiKey that was affected by a security vulnerability, and to fix the issue, Yubico sent me a brand new YubiKey for free.
