FBI Investigates Malware Embedded in Steam Games Affecting Millions of Players

The FBI is investigating a malware campaign targeting Steam users, with evidence suggesting that a single hacker has embedded malicious software in multiple games over a two-year period. The affected games include BlockBlasters, Chemia, Dashverse/DashFPS, Lampy, Lunara, PirateFi, and Tokenova. The malware, which has been active from May 2024 to January 2026, has reportedly stolen sensitive information, including account details and cryptocurrency. Valve had previously removed some of these games after discovering the malware, but many users may still be at risk. The FBI is actively seeking to identify victims and has urged players to check their libraries for potentially compromised titles. The investigation highlights significant vulnerabilities in digital distribution platforms and may lead to changes in how games are vetted before publication. The scope of the attack could potentially impact hundreds of thousands of gamers worldwide.
