As Sean Hollister of The Verge reports, an attacker nearby can use the MouseJack attack to penetrate a Logitech USB receiver connected to your computer. You can connect your devices to it and send all desired keystrokes. Only by sending a keystroke could the attacker download malware or delete your PC.
This issue was reported in 2016. To fix it, Logitech has introduced a firmware update. However, Logitech has never recalled existing devices that have been offered for sale. Even if you have bought a new device in recent years, it may be vulnerable. For some reason, this update may not even be available through Logitech's standard desktop software. You may need to make a great effort to find, download and run the problem.
To resolve the issue, visit this page on the Logitech Web site, download and install the appropriate update. For Logitech Unifying receivers (USB dongles), updates are available for both Windows PCs and Macs. If you have a Logitech G900 gaming mouse, you will also need to install a separate update.
If you are not sure whether you have ever installed the firmware update or if your new receiver came with the new firmware, just download the update and try to install it. The Updater will let you know if all your devices are up to date.
