Cybercriminals have breached insurance giant Aflac, potentially stealing Social Security numbers, insurance claims and health information, the company said Friday, the latest in a spree of hacks against the insurance industry.

Aflac says its IT teams prevented any malware from being installed, but it’s possible the hackers accessed sensitive data on users. Is the 'Scattered Spider' cybercrime gang to blame?

It’s the largest insurance company yet to fall victim to a major hacking, with tens of millions of customers and a $55 billion market cap.
