Anime Wallpaper Malware Targets Crypto Users on Steam

Malicious wallpaper downloads on Steam Workshop have been used to distribute malware targeting cryptocurrency wallets and user data. According to Kaspersky, attackers disguised their malicious software as animated desktop wallpapers featuring anime characters.

The company identified dozens of infected wallpaper packages available through the platform, with many having thousands or tens of thousands of downloads. Victims of the malware campaign were primarily in China and Russia, but infections were also seen in other countries including Singapore, Hong Kong, Germany, Vietnam, India, and Canada.

Kaspersky researchers found that the malicious wallpapers either bundled malware directly or hid it inside password-protected archives that unpacked after installation. This delivery mechanism allows attackers to reach large numbers of potential victims through seemingly harmless content.
