Altaba, Formerly Known as Yahoo!, Charged With Failing to Disclose Massive Cybersecurity Breach; Agrees To Pay $35 Million

The Securities and Exchange Commission today announced that the entity formerly known as Yahoo! Inc. has agreed to pay a $35 million penalty to settle charges that it misled investors by failing to disclose one of the world’s largest data breaches in which hackers stole personal data relating to hundreds of millions of user accounts. According to the SEC’s order, within days of the December 2014 intrusion, Yahoo’s information security team learned that Russian hackers had stolen what the security team referred to internally as the company’s “crown jewels”: usernames, email addresses, phone numbers, birthdates, encrypted passwords, and security questions and answers for hundreds of millions of user accounts.
