In an alarming trend, cybercriminals are employing increasingly sophisticated tactics to ensnare unsuspecting users, particularly with the rise of generative AI technologies. The latest scheme involves a deceptive website masquerading as a legitimate Windows 11 update, designed to lure individuals into downloading malware that can compromise their sensitive information.
Deceptive Practices Unveiled
This counterfeit site, which mimics a genuine cumulative update for Windows 11, version 24H2, has been identified by cybersecurity experts at Malwarebytes. They reported that the site operates under the domain microsoft-update[.]support, a cleverly crafted typosquatted address that closely resembles an official Microsoft support page. Written entirely in French, the site presents a convincing front, complete with a plausible KB article number and a prominent blue download button encouraging users to install the update.
What makes this situation particularly concerning is the difficulty in distinguishing the fake site from a legitimate one. Malwarebytes notes that the website’s file properties are meticulously spoofed, making it nearly impossible for users and security tools to recognize the threat.
The malware itself is ingeniously packaged as a Windows update, utilizing the WiX Toolset 4.0.0.5512, a legitimate open-source installer framework. The package, labeled “WindowsUpdate 1.0.0.msi,” features an author field that reads “Microsoft,” and a title that states “Installation Database.” The comments section even claims to contain the necessary logic and data for installing the update.
At the time of analysis, VirusTotal showed zero detections across 69 engines for the main executable and 62 for the VBS launcher. No YARA rules matched, and behavioral scoring classified the activity as low risk. This is not a failure of any single tool. It’s the intended result of the malware’s architecture.

Upon further investigation, it becomes clear that the malware conceals its malicious code within an Electron shell. While the outer layer is recognized as a legitimate framework used by numerous applications, it fails to penetrate deep enough to detect the harmful script hidden inside.
To safeguard against such threats, users are advised to always check for and download Windows updates directly through the Settings app on their Windows 11 devices. Alternatively, legitimate updates can be obtained from Microsoft’s official support hub at support.microsoft.com.
