Researchers have found several ways to exploit vulnerabilities in wireless Keyboards and Mice and can take control of them 100 meters away using the portable peripherals from at least seven big vendors including Logitech, Microsoft, and Amazon.

Tim Erlin, Director of Security and Product Management at Tripwire discusses: “We’re often so focused on network-based attacks that we forget these peripheral devices provide input to our computers as well. That wireless keyboard is another potential vector for attack.
This type of attack is unlikely to be used for large scale compromise. It’s suitable for a targeted attack against an individual.
The more successful we are at detecting the more standard, network-based attacks, the more we push the attackers to alternative methods. It’s a positive to see researchers leading the way instead of criminals.”
