The FBI is urging Steam users to report if they have ever downloaded games containing malware.

The FBI is urging players who downloaded malware-containing games on Steam between 2024 and 2026 to contact them to assist in the investigation and identify victims.

FBI investigates Steam games for malware distribution.

The Federal Bureau of Investigation (FBI) is urging players who have downloaded and installed the malware-infected games on Steam to contact the agency to assist in the investigation.

According to a statement from the Seattle branch of the FBI, the attacks primarily occurred between May 2024 and January 2026.

Steam issues a warning if the game being given contains malware.

Several games have been identified as distributing malware.

The FBI said it has identified several games linked to the incident, including:

• BlockBlayers
• Chemia
• Dashverse / DashFPS
• Mary
• Lunara
• PirateFi
• Tokenova

One notable case is PirateFi , a free game released in February 2024. This game contained malware capable of stealing login credentials and session cookies, allowing hackers to gain access to user accounts.

Players lost tens of thousands of USD.

Another notable incident involved the game BlockBlasters . After its release in July 2025, the game was infected with a cryptodrainer in August of the same year.

According to a report from BleepingComputer , at least 261 Steam accounts were hacked, resulting in the theft of approximately $150,000 worth of cryptocurrency. Among them, streamer Raivo Plavnieks (RastalandTV) lost over $32,000 while live-streaming a fundraising event.

Players should be wary of "fake" games on the Steam store.

The FBI is urging victims to provide information.

The FBI stated that identifying victims is a legal requirement in federal criminal investigations. Those affected may be eligible for assistance, compensation, or other legal rights.

Users who have downloaded the aforementioned games are encouraged to fill out the 'Seeking Victim Information' form or send information via email to the dedicated investigation team.

Although games containing malware are rare on Steam, this incident shows that the risk still exists and users need to carefully check the source of software before installing it.
