Yahoo says all three billion of its accounts were hacked in a 2013 data theft. That's triple that of an earlier estimate of the largest breach in U.S. history. Hackers put their hands on names, email addresses, phone numbers, dates of birth, passwords, and security questions and answers. SAP National Security Services' Mark Testoni. (SOUNDBITE) MARK TESTONI, PRESIDENT, SAP NATIONAL SECURITY SERVICES (ENGLISH) SAYING: "Although it's a large number, and it kind of screams out, you know, it's gosh, it's pretty significant, I do believe it's a little bit of a speed bump in the level because most of us assumed we were in the pool anyway." The news that the hack was larger than previously estimated sharply increases the legal exposure of Yahoo's new owner, Verizon. Yahoo already faces at least 41 consumer class-action lawsuits in the U.S. Verizon did not respond to a request for comment. The company paid $4.48 billion for Yahoo's core business. The price was shaved by $350 million due to the disclosure of the cyber attack last December.
