Unauthorized logins are suspected to have occurred at Nippon Television Wands, a subsidiary of Nippon Television Holdings, and information on more than approximately 117,340 accounts may have been viewed externally. Information on approximately 3,000 people is also suspected to have leaked from Tipness, while the possibility of personal information belonging to 1,040 people being leaked from Studio has been indicated.
Hiroyuki Fukuda (福田 博之), president of Nippon Television Holdings, said at a regular press conference that the group must 'strengthen its cyber defenses further.' Following a series of unauthorized access incidents within the group, he indicated a policy of strengthening countermeasures.
A third party may have logged into the administration interface of a fan community site operated by Nippon Television Wands without authorization. Names, email addresses, addresses, telephone numbers, dates of birth and other information relating to 117,392 accounts may have been viewed externally. No unauthorized use of the information has been confirmed at this time.
Information on approximately 3,000 people may also have leaked from a members-only community site operated by Tipness, another Nippon Television Holdings subsidiary. Email addresses and other information are believed to have leaked as a result of unauthorized access to an external cloud service.
Studio, one of the external services used by Nippon Television, suffered unauthorized access. The names, email addresses, addresses and other information of 1,040 people whose information Nippon Television had collected for campaigns and events may have leaked. The affected users were reportedly contacted individually.
