SEGA Network Hack Keeps Japanese Arcades Offline for Over 10 Days

SEGA's networked arcade games in Japan have now been offline for more than ten days after unauthorized access to servers behind ALL.Net, SEGA's arcade network, and Aime, its IC card service for player data. SEGA Fave, which runs both, shut the services down at 3 p.m. on November 1 and disclosed the intrusion the next day. Games like Initial D The Arcade, maimai, and CHUNITHM lost online play and card support, and since other manufacturers use ALL.Net as well, Bandai Namco cabinets such as Taiko no Tatsujin and Mario Kart Arcade GP DX went down with them. Some of those Bandai Namco machines reportedly couldn't even run offline.

Bandai Namco's titles began a trial comeback on November 8 with online play and card use restored. SEGA's own lineup is still waiting. As of 9 a.m. on November 10, the official ALL.Net service account said there was no estimate for when service would resume, with another update planned for around 9 a.m. on November 12, Japan time. SEGA Fave says it hasn't found any leaked customer or business partner data so far, and payment information like credit card details wasn't stored on the affected servers. The company hasn't said how the attackers got in.
In a separate incident, SEGA also confirmed that 2,196,044 email addresses from its newsletter lists leaked through a breach at its mail delivery contractor, Arara, which it says is unrelated to the ALL.Net intrusion. We also recently covered a similar breach in which Capcom confirmed that 11.7 million CAPCOM ID records were accessed. SEGA's own games still have no restart date, so players are stuck watching the ALL.Net account for now.
