Japan recorded 233 publicly disclosed cyberattack cases in October, the most for any month, as leaked personal data reached roughly 185 million records — nearly double the previous month.
The October figure is about 2.4 times the previous high, set in September two years ago, according to TV Asahi. The annual total has also set a record.
Trend Micro's survey found attacks using AI agents — systems that judge and act on their own — among the confirmed methods. Leaks of personal information have risen sharply as a result.
Rakusul reports possible leak of print and invoice data
Rakusul, which runs an online printing service, said unauthorized access may have exposed printing data and other information. The company detected the breach in the early hours of the 8th.
The data at risk includes print files for business cards and postcards, and names, company names, addresses and phone numbers written on invoices. Information on recipients named in printed materials may also have leaked, beyond the customers who placed the orders.
Rakusul has not disclosed the number of records affected, saying the count is still being compiled. It said no leaks of credit card or login information have been confirmed.
The company halted some services on the 8th and has been restarting them in stages from the 9th.
Disclosure becomes routine as leaks keep climbing
The record month follows a run of breaches at major organizations, including Times Car, NTT Docomo and the Digital Agency. A critical vulnerability in the PHP programming language has also left some corporate websites offline, and OpenAI has predicted attacks will rise sharply over the coming months, according to the roundup.
Card fraud is spreading as a secondary harm from stolen data, with the latest techniques using a two-stage method. A new type of virus has also been found taking over webcams to film people viewing adult sites.
