The Claim

Hackers have distributed malware through Steam Workshop items intended for the Wallpaper Engine app on Steam.

Verified by Lenz ·

The Short Version

The evidence shows that attackers did use Steam Workshop items for Wallpaper Engine to distribute malware. Security researchers documented malicious “application wallpapers” carrying credential-stealing and remote-access payloads, and Wallpaper Engine’s developers later confirmed the abuse and tightened restrictions. The important caveat is that this was not every wallpaper type, but a specific executable-capable category.

Caveats

  • The reported abuse was concentrated in Wallpaper Engine's "Application" wallpaper type, not ordinary static or video wallpapers.
  • Most coverage traces back to Kaspersky's investigation, though later reporting and developer statements corroborate the event.
  • The claim is historical: sources indicate the malicious items were identified, removed, and the feature was subsequently restricted.
