Zscaler said that the infected ISO files are usually large in size, which is more than 300MB. If you see this on the Windows 11 software download that you plan to use, the best thing you can do is disregard it since it might contain the Vidar malware. 

The cloud security firm also said that the cybercriminals use Telegram and Mastodon platforms to store their C2 IP address in the attacker-controlled account description fields. 

Security experts said that the threat actors are quite efficient when social engineering their victims into downloading the malicious Windows 11 downloads.  

How Severe is Vidar Malware? 

Let’s Hunt explained that the Vidar malware is a trojan virus that can easily steal user information from PCs and other devices. 

Cybersecurity experts first spotted this malware way back in December 2019. When it comes to function, the Vidar malware can go undetected. 

Once victims accidentally install the trojan computer virus, it will start acquiring their sensitive user data. After that, it will automatically delete itself from the system.
