April 24 (UPI) -- Federal regulators on Tuesday fined Altaba, the company formerly known as Yahoo, $35 million for failing to disclose a data breach four years ago that compromised the personal data of hundreds of millions of accounts.
Yahoo notified the public about the data breach -- which included usernames, email addresses, phone numbers and passwords -- in 2016, two years after the company learned about it. The details of the hacking became public during Verizon's acquisition of Yahoo.
