Aflac, a health and life insurer, announced on Friday that it is investigating a cyberattack on its U.S. network that may have exposed customers’ personal data. The breach was detected on June 12 and is believed to have been conducted by the cybercrime group Scattered Spider, known for targeting multiple companies in the same industry through coordinated waves of attacks.
Scattered Spider, active since May 2022, is notorious for using identity-based tactics such as scamming help desks to reset credentials and bypass multi-factor authentication. This group has been linked to recent service disruptions at Philadelphia Insurance Companies and Erie Indemnity.
Aflac’s investigation is still in the early stages, and the insurer has not disclosed the number of affected customers or the timeline for completing the review. The company handles personal, medical, and financial data of over 50 million policyholders in the U.S. and Japan, including accident and pet insurance customers.
The attack potentially exposed sensitive information, including social security numbers and health details. Aflac reported that it stopped the intrusion within hours and has engaged third-party cybersecurity experts to assist with the investigation. Despite the breach, Aflac stated that it continues to operate normally while addressing the incident.
This attack follows a wave of cyber threats in the healthcare and insurance sectors, including a major breach last year of UnitedHealth’s Change unit by the hacking group ALPHV, also known as BlackCat.
