Emails claiming to be from "Microsoft Support" or "IT Admin." Subject: "Urgent: Windows Update Required" or "License Expiration." Mechanism: A Bitly link leads to a windows.txt file that downloads a macro-laden Word document or executes a script.

:

By accessing unverified shortened links (such as bit.ly/windowstxt or bit.ly/windows10txt ), users are directed to plain-text scripts hosted on code-sharing repositories. These scripts are copied into text editors like Notepad, saved as batch files ( .cmd or .bat ), and executed with administrative privileges to unlock premium operating system features.

In this scenario, the Bitly link directs the user to a file hosted on a compromised web server or a cloud storage platform (like Google Drive, Dropbox, or Amazon S3).

Bitly’s API can be used from Windows Command Prompt or PowerShell.

Using a script sourced from anonymous URLs like bit.ly/windowstxt exposes your machine to critical risks. Microsoft Supporthttps://support.microsoft.com online & Microsoft Support Product Activation Portal
