Insurance giant Aflac identified “suspicious activity” in its U.S. network, which initiated its cybersecurity protocols. 

Aflac said it was able to stop the attack within hours, and its systems were not affected by ransomware. The company said hackers breached files that include “claims information, health information, social security numbers, and/or other personal information, related to customers, beneficiaries, employees, agents, and other individuals in our U.S. business.”
