Since the end of September, Japanese companies have successively announced incidents of unauthorised access and information leaks. While the impact of AI has been cited as a cause, efforts to strengthen countermeasures are also under way. Cases involving well-known services such as Times Car Share and Yakiniku King have also been reported, and a review of how personal information is handled is considered urgent.
Since the end of September, Japanese companies have successively announced incidents of unauthorised access and information leaks, including cases involving leaked images of driver's licences. Specifically, a leak of driver's licence images was confirmed at Times Car Share, while some cases have been reported to involve the leakage of member information.
Yakiniku King, where information on app registrants was confirmed to have leaked, is said to have experienced a leak involving more than 10 million records. Information has also been reported suggesting that all app registrants may be affected. This has intensified criticism calling for a review of policies governing the handling of personal information.
Up to approximately 950,000 member records were leaked from GMO's information security service "infoQ", and fraudulent conversion of points into cash has been reported. Concerns have once again emerged over data retention and management systems.
Overseas reports have introduced debate over the behaviour of runaway agents developed by OpenAI, raising questions about operational risks involving AI and appropriate disclosure practices. These cases are said to underscore once again the importance of strengthening corporate security measures.
