The MotW Unofficial Patch for Windows still lacks an IOC

A maliciously signed file can bypass Mark-of-the-Web (MotW) security measures thanks to an actively exploited security hole in Microsoft Windows that has an unauthorized fix available.

Threat actors can employ malicious standalone JavaScript files to get around Mark-of-the-web security warnings thanks to a Windows zero-day vulnerability. The Windows security alert that appears when attempting to open a file from the Internet is the Mark-of-the-web security feature. If you open Internet files from an unreliable or suspicious source, your computer may become damaged.

The blog released by AVERTIUM, Confirms that there are no known IOCs associated with the Mark-of-the-web vulnerability.
