What the FBI Knows
According to the FBI, the threat actor embedded malware within these games hosted on the Steam store [TechCrunch]. The games themselves were functional, but designed to act as a Trojan horse, tricking users into installing malware on their computers [TechCrunch]. While many of the games had limited popularity, one title, BlockBlasters, was reportedly used to steal approximately $32,000 in cryptocurrency from a streamer [Yahoo News], and potentially $150,000 total [Kotaku].
How the Malware Worked
Once installed, the malware could be used to steal user information or compromise the functionality of their computers [TechCrunch]. The infected games have since been removed from the Steam platform.
How to Report if You Were Affected
The FBI is asking anyone who downloaded these games between May 2024 and January 2026 to submit information via this form [FBI]. The form requests your Steam username, the games you downloaded, and the dates of download. It also asks about any unsolicited contact related to the games and any financial or digital losses experienced [Yahoo News].
What We Understand About the Investigation
The investigation is being led by the FBI’s Seattle Division [FBI]. Valve and the FBI have not yet issued public statements regarding the investigation [TechCrunch].
