Valve has taken down the game BlockBlasters from its Steam store due to the game’s involvement in stealing cryptocurrency from players’ wallets. BlockBlasters, a 2D platform game, was launched on the platform on July 30, 2025. After being available for a month without any problems, it received an update in August that included malware designed to drain crypto funds from users.

Malicious Code Uncovered

The harmful software, discovered by G-DATA, had a batch file that turned off the Anti-Virus programs on users’ computers. It gathered personal data such as IP addresses, locations, and login information. Once the security software was disabled, it would methodically check the cryptocurrency wallets installed on the computer and start emptying their balances.

Investigations and Reports

BleepingComputer has reported unverified information suggesting that the perpetrator may be an Argentine immigrant living in the United States. Scam investigator ZachXBT mentioned on X that around $150,000 in cryptocurrency was allegedly taken during the month the malware was active. Another security organization, VXUnderground, has released a list of usernames, identifying almost 478 Steam accounts impacted by this scam.

High-Profile Victim

One notable victim was Twitch streamer Raivo “RastalandTV” Plavnieks, who experienced the theft live while he was raising money for his cancer treatment. He is currently fighting Stage-4 Sarcoma. After he installed the game at the suggestion of a viewer, he ended up losing $32,000 in crypto from his wallet. This high-profile case was what ultimately prompted Valve to remove BlockBlasters from its store.
