Ukraine identifies infostealer operator linked to theft of 28,000 online store accounts

Ukrainian cyberpolice, working with U.S. law enforcement, identified an 18-year-old suspect from Odesa as a central operator in an infostealer campaign that stole browser sessions and credentials from users of a California online store between 2024 and 2025. Authorities say 28,000 accounts were compromised, 5,800 were used for unauthorized purchases totaling about $721,000, and devices and crypto-related evidence were seized in searches.
Why it matters: The case highlights ongoing risk from infostealers and stolen session tokens, which can enable account takeover and sometimes bypass MFA. Online retailers, fraud teams, and users should treat session theft as a significant threat and review account security, monitoring, and token invalidation practices.
