Windows 10 bug corrupts your hard drive on seeing this file's icon:
An unpatched zero-day in Microsoft Windows 10 allows attackers to corrupt an NTFS-formatted hard drive with a one-line command.
In multiple tests by BleepingComputer, this one-liner can be delivered hidden inside a Windows shortcut file, a ZIP archive, batch files, or various other vectors to trigger hard drive errors that corrupt the filesystem index instantly.

When exploited, this vulnerability can be triggered by a single-line command to instantly corrupt an NTFS-formatted hard drive, with Windows prompting the user to restart their computer to repair the corrupted disk records.
The researcher told BleepingComputer that the flaw became exploitable starting around Windows 10 build 1803, the Windows 10 April 2018 Update, and continues to work in the latest version.
What's worse is, the vulnerability can be triggered by standard and low privileged user accounts on Windows 10 systems.
[...] "Microsoft has a customer commitment to investigate reported security issues and we will provide updates for impacted devices as soon as possible," a Microsoft spokesperson told BleepingComputer.
