Scammers are using Windows 11, latest version of Microsoft operating system, to make a malware circulate. The system will be officially released for desktops at the end of 2021, but preliminary versions of the system are already available for download, and it is this fact that is being used by scammers. The information is from the digital security company Kaspersky.

According to the company, fraudsters are trying to trick Windows users by inserting malware into files that appear to be the system update from Microsoft. According to Kaspersky, so far, at least 850 attempts to infect users through malware disguised as Windows 11 have been detected.

A curious fact reported by the company's researchers is the size of the malware file, which is no less than 1,75 GB. Making such a large file available serves to mislead potential victims into believing that it really is an operating system installer, which is often quite large because of its complexity.

Most of the files in the package are made up of irrelevant data, which are not even used to infect the equipment. However, if the user clicks on the installer, a menu will open that simulates the Windows 11 installation wizard, but the objective is to run a second installer, which contains the malicious file.

How to prevent

To guard against this kind of scam, Kaspersky recommends some relatively simple actions, like always being very skeptical about news and offers about the new operating system that are sensational or overly generous. Experts also ask to always verify the authenticity of the places where the files are being made available.

Finally, it is important to always download important operating systems and applications such as editing packages of videos and images, always in official stores. In addition, always have an antivirus application, whether free or paid, always updated so that malicious file infections attempts are detected and its action prevented.
