Although only a small percentage of games on Steam appear to have been designed to spread malware, it’s enough that the Federal Bureau of Investigation is now looking into it. The FBI’s Seattle Division has announced that it’s attempting to identify players who were victimized by fake games on Steam that secretly infected their computers.
According to the bulletin on the FBI’s official site (via Polygon), the following games have been identified for spreading malware on Steam: BlockBlasters, Chemia, Dashverse / DashFPS, Lampy, Lunara, PirateFi, and Tokenova. The FBI describes the target of its investigation as a “threat actor,” which may imply that these infected games came from the same suspect or suspects.
Players who downloaded any of these games between May 2024 and January 2026 have been asked to fill out a form on the FBI’s site. The message also promises that information provided by potential victims will be kept confidential.
PirateFi and BlockBlasters had under 10 concurrent users before they were pulled down from Steam in 2025. However, a streamer known as RastalandTV–who is currently battling stage 4 cancer–shared a story about BlockBlasters stealing $32,000 from him after he was coaxed into downloading it.
Valve isn’t a target of this investigation, but it has been hit by a lawsuit in the United Kingdom that accuses Steam of being a monopoly. In 2021, a similar case was brought against Valve in the US before it was ultimately dismissed later that year.
