  "account": "A series of cyberattacks have compromised personal information belonging to customers of major Japanese companies, including Muji, Matsuya, and All Nippon Airways, as well as individuals associated with the Foreign Ministry. Ryohin Keikaku, the operator of the Muji retail chain, reported that up to 27.26 million accounts may have been affected, with email addresses and other data potentially exposed. Matsuya disclosed a breach affecting around 2.38 million registered users, revealing names and telephone numbers. All Nippon Airways announced that the personal data of approximately 37,800 passengers was compromised, including names, reservation numbers, passport numbers, telephone numbers, and nationalities. The Foreign Ministry acknowledged that up to 3,600 records, including email addresses and names, may have been leaked, with roughly 900 records belonging to non-government employees. The incidents have raised concerns about the security of personal data and prompted cybersecurity experts investigating a separate attack involving GMO to identify potentially significant evidence left by the hackers. The attackers made a serious mistake by inadvertently making publicly accessible records showing website visitors, which could help investigators distinguish between ordinary visitors and those involved in operating the site. By examining the timing of website modifications and visitor activity, experts suspect three IP addresses were used by the attackers. A separate cybersecurity specialist working with GMO believes the attackers may not have the operational discipline of experienced cybercriminals, potentially leading to their identification. The discoveries offer a possible lead in the GMO investigation as Japanese entities face mounting pressure to enhance cybersecurity measures.",
