Microsoft announced, on June 24 2021, that the release on Windows 11 will be happening soon and represents a significant upgrade of the Windows NT operating system, the successor to Windows 10.

The last time an update of this scale was completed was when Windows 10 was released during 2015. Hence this has caused quite a stir as everyone is eager to see what will be included. The specifics of the launch date remain unknown but it will be before the end of the current calendar year. However, some users are being offered the chance to obtain a free copy before the official launch date. 

The first Insider Preview of Windows 11 was announced by Microsoft on June 28. Installing the upgrade to Windows 11 is quite easy. A small number are being offered a simple upgrade that simply requires them to register for the Dev channel of the Windows Insider Program.  Despite the obvious dangers of downloaded software updates from unknown or unofficial sources many people have been trying to locate one.

It is no surprise that unofficial ISOs are pretending to provide Windows 11 even though they are not in a position to do so. Their true aim is to install and share malware. Hackers have been sharing these fake Windows 11 download tools to share a wide variety of malicious payloads. There is a strong chance that these fake Windows 11 installers will place adware or unwanted programs on your devices, even worse they may install malware with various degrees of maliciousness, such as Remote Access Trojans and backdoors that give the attackers full access to the victims’ devices, information stealers such as keyloggers that obtain passwords and other sensitive data, cryptocurrency miners, and ransomware.

Cybersecurity experts working at Kaspersky Lab have discovered many fake Windows 11 installers being shared around the world, including one seemingly genuine downloader titled 86307_windows 11 build 21996.1 x64 + activator.exe. Despite the title and 1.76GB file size, it was not what it appeared to be. If the user executed the file and agreed to the terms and conditions, the file would then be installed to place a different executable that places a range of malicious software onto the user’s device.

As the publicity around the official Window 11 release date ramps up, we can expect there to be many other fake installers deployed. Hackers are fond of a long-awaited software release, as it’s easy to get users to double click on executable files. Malicious adverts, websites, and emails offering free copies of Windows 11 will increase, so be careful.

If it is wise to make sure that you have an advanced and effective spam filtering solution configured like SpamTitan. This will safeguard you in the face of malicious emails. A web filter like WebTitan will protect you from malicious file downloads and see to it that you only download software or applications from authentic sources.
