In January, the Saitama Prefectural Health Promotion Corporation, a public interest incorporated foundation, was attacked by ransomware, a malicious program that encrypts files without permission and is used to demand a ransom. Together with the company and others, we have been investigating the intrusion route and whether or not there has been any damage.
The system that suffered the cyber attack stored X-ray and ultrasound images of the chest and abdomen of approximately 940,000 people who had undergone health checkups, as well as personal information such as names and dates of birth.
According to the organization, as a result of the investigation, no trace of data being stolen or leaked was found, but as multiple servers were attacked, the possibility that information was leaked cannot be ruled out. .
The organization said, ``We take this unauthorized access attack seriously and are working to strengthen security measures to prevent it from happening again.''
