Aflac recently revealed that hackers stole its customers' data in a cyberattack. Details remain scarce, but the company says it "was caused by a sophisticated cybercrime group" that's targeting the insurance industry.

Aflac, one of the largest insurance companies in the United States, says hackers stole an unknown quantity of its customers’ personal information from its network during a cyberattack earlier this month.

Customers who have insurance through Aflac may have had their data stolen: earlier this month, the company experienced a cyber attack that compromised personal information belonging to an unknown number of its approximately 50 million policyholders.
