SEGA Fave, the SEGA subsidiary that handles toys and arcade games, announced that some of its servers were hacked by an unauthorized third party. The affected servers are tied to ALL.Net, the arcade game service of SEGA, and Aime, the company’s official arcade card and service system. SEGA Fave suspended both services on November 1 while it investigates the breach, and the suspension is affecting arcades nationwide.

According to SEGA Fave, its initial investigation found no evidence that information about users or business partners was leaked. Payment-related information, including credit card details, has not been leaked or affected because it is managed on separate servers. As of November 2, several services remain unavailable. These include online gameplay for ALL.Net-compatible titles, access to arcade location information on the official websites for ALL.Net-supported games, and the use of .NET services for ALL.Net-compatible games. Gameplay using Aime or PrizeON is also unavailable, along with SEGA Lucky Kuji Online services and new SEGA ID registrations.

Many SEGA arcade machines use ALL.Net to connect to the company’s servers over the internet. Players use their Aime cards at the machines, which contact the servers to bring up each player’s information. Data such as in-game scores, ratings and items is retrieved and sent to the machine, then updated and sent back to the servers after a play session. SEGA Fave arcade games like Initial D The Arcade and Maimai DX CiRCLE PLUS are temporarily unplayable. Bandai Namco titles such as Taiko no Tatsujin and Idolmaster TOURS, which use ALL.Net’s network infrastructure, have also been affected.

SEGA Fave says it will post an update in the News section of its official webpage once the investigation and security verification are finished and a decision has been made on resuming services.
