All a Windows 10 user needs to do is extract the ZIP file or simply look at a folder that contains a malicious shortcut and it will automatically trigger hard drive corruption. Security researcher Jonas L first warned about the bug earlier this week, describing it as a “nasty vulnerability.” Attackers can hide a specially crafted line inside a ZIP file, folder, or even a simple Windows shortcut.

Microsoft says it’s planning to fix a bizarre Windows 10 bug that could corrupt a hard drive just by looking at an icon.
