The FBI is investigating malware hidden inside games hosted on Steam

The FBI is investigating a hacker suspected of publishing several video games laced with malware on the popular PC games store Steam, the agency said Friday .

In its announcement looking for victims who may have been infected, the FBI listed the following games suspected of being developed by the same cybercriminal over the last two years, hosted on the Steam store but embedded with malware: BlockBlasters, Chemia, Dashverse/DashFPS, Lampy, Lunara, PirateFi, and Tokenova.

This is not the first time hackers have been able to host malware on the Valve-owned games marketplace. Last year, hackers published several games on Steam that contained malware. The games were functional, if a bit rudimentary. In reality, the goal of their developer or developers was to act as a sort of Trojan horse, tricking gamers to install malware on their computers. Steam took the games down, but an unknown number of people were infected in the meantime.

Valve and the FBI did not respond to requests for comment.
