Dozens of malicious wallpapers found on Steam Workshop: gamers’ accounts at risk

A widespread campaign involving malicious wallpapers distributed through the Steam Workshop has been identified, targeting gamers primarily in China and Russia. Attackers are exploiting the Wallpaper Engine’s sharing feature to embed malware, specifically application wallpapers, which allow for the execution of malicious code directly on user systems. This has resulted in compromised Steam accounts, system infections with backdoors and crypto miners, and the potential for further distribution of malicious content.
