The Federal Bureau of Investigation (FBI) is investigating a series of malware-infected video games that appeared on the popular PC gaming platform Steam. The agency is now asking players who may have downloaded these compromised titles to come forward and provide information that could help identify victims and track down the people responsible.

Why it matters

The FBI's investigation highlights a growing cybersecurity concern in the gaming ecosystem, as malware disguised as games can be especially dangerous since users often trust the platform and may not suspect downloaded titles could contain harmful code. Stolen data from infected systems can lead to financial losses, identity theft, and compromised online accounts.

The details

Several titles distributed through Steam between May 2024 and January 2026 were found to contain hidden malware capable of stealing personal data and accessing user accounts. Affected games include BlockBlasters, Chemia, Dashverse, Lampy, Lunara, PirateFi, and Tokenova. The malware was designed to steal account credentials, browser cookies, and other sensitive information from infected computers.

  • The FBI investigation was launched in March 2026.
  • The affected games were distributed on Steam between May 2024 and January 2026.

The consequences of malware-infected games can be severe, leading to financial losses, identity theft, and compromised online accounts.
