FBI investigates Steam malware games that stole money and data

Mezha.Ua • March 13, 2026

The US Federal Bureau of Investigation (FBI) is collecting testimony from gamers who installed games from Steam that were infected with malware between 2024 and 2026, TechSpot reports .

The FBI's Seattle office is seeking potential victims and believes the attacker primarily targeted users between May 2024 and January 2026. The investigation uncovered several games with malicious software, including BlockBlasters, Chemia, Dashverse / DashFPS, Lampy, Lunara, PirateFi, and Tokenova.

While most of the games identified were not very popular, they could still be harmful to users. Early last year, it was reported that the game PirateFi contained malware that stole account details and other information. Although the game was released on February 6 and had only been available in the store for a few days, the attackers likely managed to obtain the data of several hundred people.

One of the games mentioned on the FBI website is the platformer BlockBaster, which has been available on Steam since July 30. As it turned out later, on August 30, a crypto-drainer component was added to it, which caused the streamer RastalandTV to lose $32,000. In total, the developers stole $150,000.

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. 40 sources 71
