Yahoo on Thursday reported the largest data breach in history — affecting at least 500 million user accounts — months after first detecting signs of an intrusion that the company blamed on “state-sponsored” hackers.The web giant called on customers to change their passwords and institute other protective measures, but the largest fallout could be for Yahoo itself. The long-faltering company this summer agreed to sell its core business for $4.8 billion to telecommunications giant Verizon in a deal now clouded by news of the massive breach. Verizon said it learned of the incident only “within the last two days.”
