Logitech’s Unifying Receiver (wireless dongle) is vulnerable to some newly discovered vulnerabilities, updating the firmware will patch the flaws.
If you use a Logitech Unifying Receiver (also knows as the wireless dongle) download and install the latest firmware update to protect against vulnerabilities. Unless you’ve updated the firmware, the Logitech Unifying Receiver is still vulnerable to an issue discovered in 2016 as well as some newly discovered vulnerabilities.
Logitech didn’t recall the Unifying Receiver back in 2016 when the hack called “Mousejack” appeared. Many of the Unifying Receivers were still on the market, though Logitech started releasing updated dongles sold with mice, keyboard and stand alone receivers. Not long after the discovery, Logitech issued a firmware update but it wasn’t widely known and the firmware isn’t all that easy to find on the site. If you didn’t update the firmware then (and most of us didn’t know about it) now is a good time to get the update as new vulnerabilities have been discovered.
Logitech isn’t the only company that’s been affected; any device that uses the same Nordic and Texas Instruments chips and firmware for wireless receivers are impacted, including devices from Microsoft, Dell, HP, and Lenovo. If you use a wireless device from one of those companies, you might want to check if the firmware can be updated. Logitech lets you update the firmware on the wireless dongle.
