Testing by Bastille revealed that with the use of a long-range radio dongle ($15-$30) and a couple of lines of code, they could intercept and hijack USB dongle radio signals at a distance of up to 100 meters. Using the MouseJack attack, a nearby attacker could install a rootkit on your PC in about 10 seconds:
The hacker can, therefore, send packets that generate keystrokes instead of mouse clicks, allowing the hacker to direct your computer to a malicious server or website in mere seconds.An illustration of the attack can be seen in the video below:
During their tests, researchers were able to generate 1000 words/minute over the wireless connection and install a malicious Rootkit in about 10 seconds. They tested several mice from Logitech, Lenovo, and Dell that operate over 2.4GHz wireless communications.
A list of affected devices can be found at Bastille. Logitech confirmed the issue and rolled out a security update.
