A sophisticated fake Windows update site has emerged, designed to mimic Microsoft’s branding to distribute malware, specifically targeting individuals seeking early access to Windows 11 version 24H2. The fraudulent site resembles a legitimate cumulative update download page, using familiar design elements to evade detection. The malware operates as an information-stealing entity, targeting saved passwords and browser sessions, potentially bypassing two-factor authentication. It transmits stolen credentials through encrypted channels to external servers. The installer uses legitimate packaging tools to minimize detection and employs obfuscated scripts within legitimate software components. The campaign modifies system startup entries and creates disguised shortcuts to maintain persistence. Researchers noted the use of a typosquatted domain and meticulously spoofed file properties. As of April 2026, Microsoft has not released Windows 11 version 24H2 to the public, and legitimate updates are only available through Windows Update. Users are advised to obtain updates exclusively through official channels and keep security features updated.

A recent discovery by Malwarebytes has identified a cyber threat involving a typosquatted domain that mimics official Microsoft support pages. This site uses authentic branding and KB-style reference numbers to deceive users into downloading what appears to be a legitimate cumulative update. The malware, once installed, operates stealthily, stealing passwords from browsers and active sessions, which allows attackers to bypass two-factor authentication. The stolen data is sent to external servers through encrypted channels. Initial scans showed zero detections by multiple antivirus engines due to the malware's obfuscated scripts. It also modifies system startup entries and creates disguised shortcuts for persistence. Microsoft has not yet released Windows 11 version 24H2 to general users, and updates should only be obtained through official channels to avoid potential threats.

Cybercriminals are using sophisticated tactics to deceive users, particularly with a counterfeit website posing as a legitimate Windows 11 update. This site operates under the domain microsoft-update[.]support and is designed to trick individuals into downloading malware that compromises sensitive information. The site is written in French and mimics a genuine cumulative update for Windows 11, version 24H2, featuring a convincing KB article number and a blue download button. The malware is packaged as a Windows update using the WiX Toolset 4.0.0.5512 and is labeled "WindowsUpdate 1.0.0.msi," with properties that suggest it is from Microsoft. At the time of analysis, VirusTotal showed no detections for the malware, which conceals its harmful code within an Electron shell, making it difficult to identify. Users are advised to download updates directly through the Windows Settings app or from Microsoft's official support hub.

A new malware campaign targets Windows users by using a fraudulent clone of a Microsoft website to steal sensitive information. Victims are directed to a typo-squatted web address that resembles an official site, where they are prompted to download a file named WindowsUpdate 1.0.0.msi. This file uses a legitimate open-source installer framework and incorporates Electron, JavaScript, and Python, making it difficult to detect; VirusTotal showed zero detections across 69 engines. The malware maintains persistence by modifying the Windows registry and placing a shortcut named Spotify.lnk in the startup folder. Currently, the campaign primarily targets French-speaking users, but similar tactics may spread to other regions. Users are advised to apply updates only through the Windows Update feature in the Settings menu.

Claude, an AI tool developed by Anthropic, receives nearly 290 million web visits monthly and has become a target for cybercriminals. A fake website has been found that impersonates Claude, distributing a trojanized installer named Claude-Pro-windows-x64.zip. This installer, while appearing legitimate, deploys PlugX malware, granting attackers remote access to users' systems. The fraudulent site mimics the official download page and uses passive DNS records linked to commercial bulk-email platforms, indicating active maintenance by the operators. The ZIP file contains an MSI installer that incorrectly spells "Claude" as "Cluade" and creates a desktop shortcut that launches a VBScript dropper. This script runs the legitimate claude.exe while executing malicious activities in the background, including copying files to the Windows Startup folder to ensure persistence after reboot. The attack utilizes a DLL sideloading technique recognized by MITRE as T1574.002, where a legitimate G DATA antivirus updater is exploited with a malicious DLL. Within 22 seconds of execution, the malware establishes a connection to an IP address associated with Alibaba Cloud, indicating control over the compromised system. The dropper script also employs anti-forensic measures to delete itself and the VBScript after deployment. Indicators of compromise include the filenames Claude-Pro-windows-x64.zip, NOVUpdate.exe, avk.dll, and NOVUpdate.exe.dat, along with the network indicator 8.217.190.58:443 (TCP) as the command and control destination. Users are advised to download Claude only from the official site and to remain vigilant against potential compromises.
