Security Vulnerabilities in Wireless Keyboards
An attacker can launch the attack from up to 100 meters away. The attacker is able to take control of the target computer, without physically being in front of it, and type arbitrary text or send scripted commands. It is therefore possible to perform rapidly malicious activities without being detected.
The MouseJack exploit centers around injecting unencrypted keystrokes into a target computer. Mouse movements are usually sent unencrypted, and keystrokes are often encrypted (to prevent eavesdropping what is being typed). However the MouseJack vulnerability takes advantage of affected receiver dongles, and their associated software, allowing unencrypted keystrokes transmitted by an attacker to be passed on to the computer’s operating system as if the victim had legitimately typed them.
Logitech said that it has developed a firmware update, which is available for download. It is the only one among the affected vendors to respond so for with a patch.
“Logitech’s Unifying technology was launched in 2007 and has been used by millions of our consumers since. To our knowledge, we have never been contacted by any consumer with such an issue,” Asif Ahsan, Senior Director, Engineering, Logitech. “We have nonetheless taken Bastille Security’s work seriously and developed a firmware fix. If any of our customers have concerns, and would like to ensure that this potential vulnerability is eliminated…They should also ensure their Logitech Options software is up to date.”
