Sega Fave has taken its Aime and ALL.net services offline after a third party accessed them without authorization. The outage has affected online services for a range of Japanese arcade games, including Bandai Namco’s Taiko no Tatsujin and Sega’s Initial D: The Arcade.
The disruption began on November 1 at 3 p.m. Japan local time, according to the report. ALL.net connects arcade machines to online features such as multiplayer matches, leaderboards and saved data. Aime uses NFC cards to identify players and access their information at supported machines.
Sega Fave, the Sega subsidiary responsible for the services, is investigating the breach. Sega says no customer or business partner data was compromised, and that payment information was not stored on the affected servers. The company has not disclosed the nature of the unauthorized access.
The outage has left some arcade machines unavailable, while some venues have restricted games to offline play. Sega updated its notice on November 2, saying the investigation would take time. The services had also been offline for several days late last month while Sega addressed a PHP exploit; when they returned, access was limited to Japan.
