A rather unusual vulnerability in Razer mice has been identified and the company is currently working on a fix. Over the weekend, security researcher Jon Hat posted on Twitter that after plugging in a Razer mouse or dongle, Windows Update will download the Razer installer executable and run it with SYSTEM privileges. It also lets you access the Windows file explorer and Powershell with "elevated" privileges — which essentially means someone with physical access to the computer could install harmful software.
