The FBI is investigating a malware campaign that infected computers through several games on the Steam platform. The agency believes malicious software was distributed via titles like BlockBlasters, Chemia, and PirateFi between May 2024 and January 2026. The FBI is now seeking information from potential victims to provide services and restitution.
The FBI is investigating the distribution of malware through several video games hosted on Steam. The agency said Friday it is seeking victims whose computers may have been infected after downloading games believed to contain malicious software.
The FBI’s investigation targets several PC games, including BlockBlasters, Chemia, Dashverse, DashFPS, Lampy, Lunara, PirateFi, and Tokenova. The FBI believes the threat actor primarily targeted users between May 2024 and January 2026.
Last summer, several games, including Chemia and PirateFi, were removed by Steam after they were discovered to include malware. While the infected titles appeared to be games approved for sale on the platform, they instead installed malware on players’ computers.
The FBI is seeking information from gamers who may have been affected. “The FBI is legally mandated to identify victims of federal crimes it investigates,” an FBI spokesperson stated.
“Victims may be eligible for certain services, restitution, and rights under federal and/or state law. All identities of victims will be kept confidential,” they said, adding that the agency is unable to provide specific details.
Malware targeting gamers has appeared in both game downloads and third-party tools linked to popular titles. In 2023, a fan game based on Nintendo’s Super Mario franchise was found to contain malware capable of hijacking cryptocurrency wallets and installing crypto-mining software.
In March 2024, cybersecurity firm VX Underground warned that players searching for cheat software for Call of Duty were exposed to malware capable of draining Bitcoin wallets. The attack potentially affected more than 4.9 million gaming accounts across multiple platforms.
