Background
ALL.net is an online network that allows machines in Japanese arcades to connect to the internet, providing online matches, leaderboards, and save data sharing. Aime is a service working with NFC cards that stores player information, tapped at any machine for use. The account number on these cards can be accessed online by Sega to verify information.
The Aime service is provided by Sega but is also licensed by companies like Bandai Namco for games such as Idolm@ster TOURS and Taiko no Tatsujin. Sega also uses it for non-arcade services like Lucky Kuji Online. Prior to this incident, Sega took down the same service for multiple days at the end of the previous month to address a PHP exploit, reopening it with access limited to Japan.

Sega takes ALL.net and Aime services offline
Sega Fave, the subsidiary in charge of the service, reportedly stopped ALL.net and Aime services at 3 p.m. local time in Japan to address what it described as unauthorized access by a third party. The company said that no customer or business partner data had been breached and that payment information was not stored on the affected servers.[1]

Sega updates notice on investigation timeline
Sega reportedly updated its public notice to inform users that the investigation into the unauthorized access is expected to take some time to complete, according to the notice. Social media users reportedly shared images of arcades with machines blocked from public use or limited to offline mode.[1]
-
Arcade operators report continued service disruption
The post noted that operating machines might reportedly also stop without notice. Kotaku reported that the service reportedly had yet to return two days after the initial outage.[2]

Arcade operators report continued disruption
According to ITmedia, multiple game centers reported partial machine shutdowns and feature restrictions on X as of 13:00 on November 4.[5]
Our read of the evidence
Mostly unverified. All three timeline events rest on reports from two outlets — kotaku.com and a Twitter post — with none confirmed by a primary source. Sega's statement that no customer data was breached comes through kotaku.com, while arcade operators' reports of continued disruption come from Twitter. The investigation into the extent of unauthorized access remains pending per the company's November 2 notice.
Our rating counts evidence, not opinions about anyone: events confirmed by a primary source (the person's own post, their official site, a court or government record) weigh most, then how many independent outlets report the story.
