Are Wireless Keyboards a Security Risk? Meet KeyKeriki

How secure are wireless keyboards? Could they be hacked? The answer, unfortunately, is yes. I read a while back that wireless keyboards could theoretically be hacked, thus they are a security risk. Well, now it has been done.

Meet KeyKeriki, a universal wireless keyboard sniffer. It appears that when it came to wireless keyboard design, that security was not a top priority. Some keyboards use no encryption and most use an easily broken encryption. The KeyKeriki can even decrypt Microsoft’s xor encryption. It is not just for sniffing keystrokes, it can also be used to send commands to your computer.

According to the creators, “Keykeriki is build around the Texas Instruments TRF7900 chip controlled by an ATMEL ATMEGA 8-bit microcontroller. For logging abilities, an SDCard interface is built into the board layout, as well as an additional USART channel for future hardware extensions, that we’d like to call “backpacks”. The whole board can be powered directly via the USB bus or a stable 5V power source.”

The cost of such device? It has been released as open-source, so you can download the schematic and software for free. So if you are on a secure system, never, ever use a wireless keyboard, as whatever you type could be intercepted. For more information, see Remote-Exploit.
