According to cybersecurity company Bastille, KeySniffer is a huge vulnerability that affects several brands and models of wireless keyboards, including HP, Toshiba, Kensington, Insignia, Radio Shack, General Electric and more. KeySniffer allows third parties to remotely access the keystrokes from users from up to 250 feet away. The data is transmitted via clear text and can offer up passwords, credit card numbers and other types of sensitive data.
Bastille tested keyboards from 12 different manufacturers and found that eight of them were susceptible to the attack. Kensington has already made efforts to patch the vulnerability, adding AES to its wireless keyboards' broadcast, but if you find yourself consistently using one of the brands tested it could be worth looking into a different model or at the very least opting for Bluetooth. There are enough breaches out there to have to worry about yet another one coming from an item you could be using every day.
