Do you use a Logitech wireless mouse or keyboard on your PC or Mac? There is a good chance your device is vulnerable to the "MouseJack" attack. Devices sold before 2016 are vulnerable, but many devices sold after are also vulnerable.

Like Sean Hollister at The edge According to reports, the MouseJack attack allows a nearby attacker to break into a Logitech USB receiver connected to your computer. They can connect their devices and send all the desired keyboard inputs. By simply sending a keyboard entry, the attacker could download malware or erase your PC.

This problem was reported in 2016. To address this problem, Logitech has deployed a firmware update. However, Logitech never recalled the existing devices offered for sale. Even if you have bought a new device in the last few years, it could be vulnerable. This update may not even be available through Logitech's standard desktop software for any reason. You may have to go out of your way to find, download and run it.

To solve the problem, visit this page on the Logitech website, download the appropriate update and install it. For Logitech unified receivers (USB sticks), updates are available for Windows PCs and Macs. There is also a separate update to install if you have a Logitech G900 gaming mouse.

If you do not know if you have already installed the firmware update or if your new receiver comes with the new firmware, simply download the update and try to install it. The update program will tell you if all your devices are up to date.

As Logitech notes, this tool will also update the firmware of some specific vulnerable Logitech wireless keyboards at the same time. Make sure they are connected when running the updater:

If you have K780 MULTI-DEVICE WIRELESS KEYBOARD, KEYBOARD K375s MULTI-DEVICE, KEYBOARD KEYBOARD K400 PLUS KEYBOARD KEYBOARD, MK850 PERFORMANCE or ILLUMINATED LIVING-ROOM KEYBOARD K830 connected to your Unifying receiver, the tool will guide you to update the firmware on the keyboard well.
