Users should be on the alert for fake Windows 11 installers files on the internet, according to cybersecurity firm Kaspersky.
On July 27, the firm released research findings on how fraudsters exploited customers’ excitement for the OS.
In a statement, Kaspersky security specialist Anton V. Ivanov stated, “The new Windows 11 operating system is a big release, which captures the interest of many users and computer aficionados.”
“Fraudsters have swiftly evolved to meet this demand, spreading numerous forms of malware disguised as the new operating system.”
Microsoft released the latest edition of its Windows operating system last month.
Windows 11 will be available at the end of 2021, and Windows 10 users will be able to upgrade in early 2022.
Prior to that, Microsoft gave members of its Windows Insider program the first look at the OS.
850 attempts to infect consumers’ devices were discovered and blocked by Kaspersky in the first month following Microsoft’s revelation. The files ostensibly contained Windows 11 software.
One malicious 1.75GB file was discovered, which executed a second installer under the guise of a false Windows installation wizard. Without the user’s awareness, the installer would install undesirable or virus apps on the device.
“If customers are too eager to try out the new OS, they are less likely to pay attention to the process and may download files from third-party sites, which we strongly warn against,” Ivanov stated.
“And attackers are only too willing to help them.”
How to Spot Fake Windows 11 Setups
At the same time, Kaspersky suggested many strategies for consumers to avoid downloading malicious files and falling for bogus OS installations.
It advised customers to be wary of any offers or promotions for the new OS that seemed too good to be true.
They must also verify the legitimacy of websites they visit and only get Windows from authorized sources.
