- Quick Answer: The FBI is investigating several Steam games suspected of distributing malware that could steal personal data, cryptocurrency, and account information from players’ computers.
The Federal Bureau of Investigation has launched an investigation into several games that were previously available on Steam after discovering that some titles were secretly distributing malware to players.
The investigation is being handled by the FBI’s Seattle division, which is now attempting to identify people who may have been affected.
Authorities believe the activity took place over a long period, with suspected malicious games appearing on the platform between May 2024 and January 2026.
Which Steam Games Are Connected to the Investigation?
According to the FBI, the games currently tied to the investigation include BlockBlasters, Chemia, Dashverse (aka DashFPS), Lampy, Lunara, PirateFi, and Tokenova.
These games appeared legitimate when they were first released and were distributed like normal titles through Steam.
Many players likely downloaded them without realizing anything unusual was happening behind the scenes. Since the games included genres like shooters and platformers, they easily blended in with the many other titles available on the storefront.
In some cases, the malicious code was not necessarily present in the very first version of the game. Reports suggest that certain titles were initially harmless but later introduced malware through updates or patches.
This tactic made the threat harder to detect because players who had already installed the game might have unknowingly downloaded the infected update afterward.
One title reportedly encouraged users to opt into a playtest version, which may have been another method used to distribute harmful software.
What Could the Malware Do to Players’ Computers?
After installation, the malware hidden inside these games could perform several harmful actions, including stealing personal data, compromising accounts, or disrupting a computer’s normal operation.

Authorities are particularly interested in whether victims experienced financial losses or had digital assets stolen.
This includes stolen cryptocurrency, drained bank accounts, missing Steam inventory items, or unauthorized access to other online services connected to the affected computers.
One widely cited example involves the game BlockBlasters, which reportedly had very few players but was still linked to a significant theft involving cryptocurrency.
In one account shared publicly, a player claimed that tens of thousands of dollars in digital assets were taken after installing the game.
While the exact details of that incident remain difficult to verify publicly, the scale of the reported losses highlights why federal investigators are treating the situation seriously despite the relatively small player numbers involved.
Even though these titles were not widely popular on Steam, the FBI suspects they could be linked to a broader operation.
Officials have described the perpetrators as “threat actors,” suggesting that the malware may have been distributed by the same individual or coordinated group.
Investigators believe the people behind the scheme could be operating within a larger ecosystem that includes developers, affiliates, and service providers who work together to distribute malicious software while constantly adjusting their techniques to avoid detection.
What Information Is the FBI Asking From Players?
To help build a clearer picture of the situation, the FBI has set up a public reporting form asking potential victims to come forward.
Players who believe they may have downloaded one of the affected games are encouraged to provide details such as their Steam username, the titles they installed, and the approximate date they downloaded them.
The form also asks whether anyone contacted them before or after installing the game, which may help investigators determine whether the malware campaign involved direct communication with targets.
Additionally, the agency wants to know whether victims experienced any financial losses or suspicious activity tied to their digital accounts.
Authorities have said that anyone who submits information may later be contacted for additional details as the investigation continues.
However, the FBI has also stated that the identities of victims who report their experiences will remain confidential.
