Windows Command Scripts to disable Registry security, add Defender exceptions, uninstall security products, and delete the shadow disc are two of the four files lost. Persistence is achieved by placing a.LNK (shortcut) file in the Startup directory and setting its access rights with icacls.exe. The loader uses the CreateProcess Windows API to help create new processes, establish persistence, and plant four files, according to CloudSEK. The loader writes 3,078KB of data to the TMP file. The “Windows 11 setup” programme provided in the ISO is the loader file (Delphi-based), which, when started, dumps a temporary file named is-PN131.tmp and produces another. The threat actors behind this effort, according to CloudSEK, are using a new malware called “Inno Stealer” since it uses the Inno Setup Windows installer.Īccording to the researchers, Inno Stealer has no code in common with other currently circulating info-stealers, and there is no evidence of the virus being uploaded to the Virus Total scanning site. If a visitor accesses the malicious website directly (download is not possible via TOR or VPN), they will receive an ISO file containing the executable for new data-stealing malware.ĬloudSEK threat researchers researched the ransomware and shared a technical report with BleepingComputer exclusively. The official Microsoft emblems, favicons, and a welcoming “Download Now” button are all included. The hackers are preying on people who rush to install Windows 11 without first learning that the OS must meet certain requirements.Īt the time of writing, the rogue website advertising the false Windows 11 was still active. Support for the Trusted Platform Module (TPM) version 2.0, which is found on machines that are less than four years old, is one of the requirements. Users can use Microsoft’s upgrade tool to see if their machine is compatible with the company’s most recent operating system (OS).
