Japanese teen arrested over cyberattack that disrupted anime streaming service

Tokyo police arrested a 15-year-old who exploited a flaw in the Bandai Channel streaming platform to cancel over 46,000 user subscriptions in November 2025; the attacker analyzed network traffic, developed an automated tool with ChatGPT, and evaded blocks by repeatedly changing IP addresses, forcing the service offline for more than a month while repairs and refunds were made.
