Arcade games across Japan have been left unplayable as SEGA responds to a cybersecurity attack on the ALL.Net service.

In an announcement from November 2, the company revealed that certain parts of its servers were accessed without authorization by a third party. As a result, services such as ALL.Net, Aime, and PrizeON were taken down while the investigation is ongoing. Much like the recent incidents with Good Smile Company and Comic Cmoa, no timeframe has been given on restoration.

Given that Bandai Namco Entertainment partnered with SEGA to bring cross-functionality between several different IC cards in 2018, games such as The Idolmaster Tours and Taiko no Tatsujin are also down alongside Maimai and Initial D The Arcade.

SEGA responded to the previous PHP vulnerability by blocking access to the Aime website from IPs outside of Japan.
