Aflac Life Insurance Japan, a subsidiary of insurance giant Aflac, on Tuesday announced that hackers stole the personal information of 4.38 million customers. The company’s systems were hacked on June 15, and the attackers accessed them several times until June 25, when the data breach was discovered, Aflac said in a filing with the US Securities and Exchange Commission. “Upon identifying the unlawful access, Aflac Japan promptly took steps designed to contain the incident and prevent further intrusion, including suspending certain systems,” Aflac said. The incident is limited to certain Aflac Japan systems and does not affect Aflac’s systems related to the US business, the insurance giant told the SEC. According to an FAQ published on Aflac Japan’s website, at least five services have been disrupted as a result of the incident. For the time being, the company could not estimate when the affected services may be restored.
