Analysis Summary
Vidar, which first appeared in late 2018, is a malware family that primarily acts as an information stealer and is frequently seen as a prelude to ransomware distribution. This malware takes data and distributes it as spam email, cracked commercial software, and keygen programs. Vidar can scrape a wide range of digital wallets in addition to credit card data and passwords. Various campaigns can be used to propagate this malware. It allows data such as system information, browser data, and passwords to be captured and exfiltrated from a system. Vidar has also been seen as a secondary payload in ransomware attacks like STOP/DJVU.
Researchers discovered newly registered domains created by a threat actor to spoof Microsoft’s official Windows 11 OS download portal in April 2022. The fake sites were set up to spread malicious ISO files that infect endpoints with the Vidar infostealer. These Vidar malware variants fetch their C2 configuration via attacker-controlled Telegram and Mastodon social media channels.
