SEIKO Group Corporation (SGC) has announced that they suffered a cyber attack that exposed customer data. 

The attack lasted for several months and was ransomware that accessed SEIKO’s servers without permission. 

The attack was discovered on July 28, 2023, and SEIKO immediately stopped it.

SEIKO hired cybersecurity experts to investigate and report the attack to the authorities. 

They also set up an emergency team to limit the damage. After checking their servers, they discovered about 60,000 pieces of personal data from SGC, Seiko Watch Corporation (SWC), and Seiko Instruments Inc. (SII) were leaked.

The data included customer names, business contacts, job applicants, and staff information.

SEIKO has done several things to fix the problem and avoid future attacks. 

They cut off external communication with the affected servers and installed new systems to detect and block unauthorized activity. 

They also added more security features, such as multi-factor authentication.

SEIKO is still working with cybersecurity experts to find and fix any weaknesses in their IT systems, figure out the full extent of the data leak, understand how and why the attack happened, improve system security and monitoring, strengthen corporate governance across the Group, review their Business Continuity Plan (BCP), and get third-party assessments and other actions to prevent such incidents from happening again.

SEIKO Group Corporation apologized for the trouble caused by this data leak. 

They have contacted the affected parties individually and are ready to deal with any more leaks that may be found later.
