Hackers Break into Licensing System in Windows and Microsoft Office
The Massgrave hacker group has cracked Microsoft’s licensing system, allowing it to activate nearly all versions of Windows and Microsoft Office, including volume licenses with Extended Security Updates (ESU).
Massgrave claims that the exploit is capable of activating a wide range of Microsoft products, including Windows Vista, Windows 11, Windows Server 2025, and modern versions of Office. On the X platform, the hackers called their exploit “the biggest breakthrough in Windows/Office piracy ever.”
The new activation method, which hackers are calling revolutionary, allows you to bypass almost the entire security scheme underlying the Windows and Office licensing model without modifying system files or installing third-party software. Massgrave claims that the exploit covers not only current versions of Windows and Office, but also Extended Security Updates (ESU) licenses. This allows you to extend the period of security updates for Windows 10, which will end official support in October 2025.
As evidence, the MASSGRAVE hackers published screenshots of activated versions of Windows with ESU, confirming all their claims. The hackers intend to make their activation tool publicly available in the coming months.
