The U.S. Federal Bureau of Investigation has opened an investigation following reports that malicious software has been distributed through the Steam digital storefront. The bureau published information about the inquiry on its official website, warning users and outlining the scope of its review.
The probe was prompted by an uptick in incidents where titles released on Steam turned out to be disguised malware. According to the FBI, these attacks most frequently occur in the indie game segment, where products often have smaller audiences and fewer safeguards against malicious uploads.
The FBI has asked players who believe they were targeted by these deceptive games between May 2024 and January 2026 to come forward and provide testimony. In its announcement the bureau used language suggesting that the series of incidents could be the work of a single individual or a coordinated group rather than isolated actors.
Investigators have identified several games that were linked to the distribution of unwanted software. Among the titles named were BlockBlasters, Chemia, Dashverse (also noted as DashFPS), Lampy, Lunara, PirateFi and Tokenova. The games reportedly installed various programs on users’ computers designed to harvest information or otherwise compromise systems.
In one documented example, actors using a malicious variant of BlockBlasters are reported to have stolen more than $150,000 in cryptocurrency from victims. Other affected titles similarly installed tools intended to collect different types of data from infected machines.
The FBI’s announcement underscores ongoing risks in digital distribution channels and the need for users and platform operators to remain vigilant. The investigation is active, and authorities encourage anyone affected during the stated period to contact the bureau to assist with the inquiry.
