Personal data has been exposed one company after another, including Yakiniku King, with announced data breaches totaling approximately 10.8 million records. The use of AI in large-scale cyberattacks has been cited as a possible cause, while data leaks continue to occur at other companies as well.
Monogatari Corporation, the operator of Yakiniku King, announced that a third party had gained unauthorized access to the membership management system for its official app, exposing personal data including names, telephone numbers and email addresses. The number of exposed records is reportedly approximately 10.8 million.
MrMax, a discount store chain operating in the Kanto and Kyushu regions, also announced that member data for up to approximately 1.74 million people may have been exposed. Citizen Watch reported unauthorized access to its inquiry form, with the possible exposure of names, addresses and other information for approximately 100,000 people, as well as bank account and credit card information. At Times CAR, images of approximately 1.6 million identity verification documents may have been exposed.
Experts who analyze cyberattack trends in detail have suggested that AI may be being used in attacks and said that attacks targeting Japan appear to be spreading. Government officials also commented that individual countermeasures can help prevent damage.
