Steam malware campaign allegedly stole at least $220,000 from crypto wallets
Prosecutors allege the eight-game operation infected about 8,000 devices and compromised roughly 80 crypto wallets between May 2024 and January 2026.
The FBI is seeking potential victims in connection with an alleged Steam malware scheme tied to crypto theft, a case that highlights how wallet risk can occur even before a user’s wallet is formally accessed. According to CryptoSlate, a federal complaint reported by Local 10 says the eight-game campaign infected about 8,000 devices and gained unauthorized access to roughly 80 crypto wallets, stealing at least $220,000.
Local 10 reported that agents arrested 21-year-old Zyaire Dontaevious Zamarion Wilkins on July 14 and accused him of financing and procuring malware and helping market the infected games. The complaint lists suspected Steam titles as BlockBlasters, Chemia, Dashverse, DashFPS, Lampy, Lunara, PirateFi and Tokenova, with the activity spanning May 2024 through January 2026.
The alleged campaign promoted the games on Discord, Telegram, X, and LinkedIn, with bots reportedly identifying users with large crypto holdings and sending targeted messages encouraging them to download. Once installed, the malware is alleged to have captured private data and credentials, and to have included tactics discussed for tricking victims into authorizing transactions that emptied wallets.
CryptoSlate also points to a separate February 2025 cyber advisory describing PirateFi as available on Steam for a limited window in 2025, and naming the Vidar infostealer, which could steal credentials, session cookies, and crypto wallet information. The reporting notes that Steam’s review and update processes create multiple points of exposure, and that wallet users may need to treat official marketplaces as not the only trust boundary.
