The FBI is investigating a hacker responsible for releasing several video games with embedded malware on the Steam platform. The suspected games include BlockBlasters, Chemia, Dashverse/DashFPS, Lampy, Lunara, PirateFi, and Tokenova. These games were developed over the past two years and posed risks to gamers who downloaded them. This incident follows a similar event from the previous year when malware-laden games were also uploaded to Steam. Neither Valve nor the FBI has commented on the investigation.
