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.
"Critically underestimated" NTFS vulnerability
In August 2020, October 2020, and finally this week, infosec researcher Jonas L
drew attention to an NTFS vulnerability impacting Windows 10 that has not been
fixed.
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.
