FBI Launches Investigation Into Steam Malware Games

The FBI is now actively investigating a series of malware-infected games on Steam that are believed to be part of a broader crypto scam operation.

The agency's Cyber Division has set up a dedicated web page to gather information from potential victims and the public.

Several games have been identified as the primary suspects in this case. These include BlockBlasters, Chemia, Dashverse, Lampy, Lunara, PirateFi, and Tokenova.

On the surface, these titles looked and played like completely normal Steam games. They spanned multiple genres too, ranging from FPS titles to platformers, which made them harder to flag at first glance.

This malware was typically distributed through in-game patches that were later found to be suspicious. At least one early access title reportedly prompted players to opt into a playtest before injecting dangerous software onto their machines.

The FBI believes the primary threat actor behind these games was active on Steam between May 2024 and January 2026.

As per the bulletin posted on the FBI's official site, the agency is currently working to identify players who were victimized by these fake games. Players who downloaded any of the listed titles during that period are being encouraged to fill out a form on the FBI's website.

Valve acted quickly to remove the offending titles once their nature was discovered. BlockBlasters, for instance, never managed to reach more than seven concurrent users, according to SteamDB. Despite that tiny footprint, the damage it caused was real. A streamer named RastalandTV, who's battling stage 4 cancer, came forward with a story about BlockBlasters stealing $32,000 from him after he was tricked into downloading it.

Separately, BlockBlasters has also been accused of robbing at least one player of $150,000 in cryptocurrency, though that specific claim has not been independently verified.

It is worth noting that Valve itself is not a target of this investigation.

The FBI has kept its findings fairly close to the chest for now. What is clear is that it wants to hear from victims. The agency has assured the public that all identities will be kept confidential.

If you downloaded any of the listed games between May 2024 and January 2026, it may be worth checking out the FBI's dedicated page and submitting a report.
