You need to update your Logitech wireless dongle now

If you own a wireless Logitech device, we’d suggest you update those wireless dongles now. A few years ago, hackers discovered that they can exploit a vulnerability in these dongles, allowing them to remotely control a PC. And according to The Verge, some products Logitech are still shipping today could still be vulnerable to the same remote access hack called MouseJack. Some of the products include Logitech’s Unifying Receiver and G900 wireless gaming mouse. The company did roll out patches that fixed the remote access vulnerability back in 2016. But we don’t know when (or if) these changes were applied to devices that were in the factory. You might have purchased an unpatched model. In a statement issued to The Verge, Logitech said, “Logitech evaluated the risk to businesses and to consumers, and did not initiate a recall of products or components already in the market and supply chain. We made the firmware update available to any customers that were particularly concerned, and implemented changes in products produced later.”
Just to be sure, we highly recommend you install the patch. If you have any of Logitech’s Unifying receivers, you can download the patch for Windows here and the one for Mac here. If you have the G900 gaming mouse, you can download the patch for Windows here. Once downloaded, simply follow the on-screen instructions to apply the patches. Logitech intends to push an additional update that fixes a related vulnerability next month. Make sure you have the necessary Logitech software installed and that you install updates as they arrive.
