Yahoo now says all 3 billion of its accounts affected by security breach

Yahoo revealed Tuesday that a massive cyberattack it suffered in 2013 was much more widespread than it previously said, according to regulatory filings.
 
The web portal now says all 3 billion Yahoo accounts were compromised in the breach. The company initially said only 1 billion had been hit when it first disclosed the hack last December.

That means that absolutely everyone who had a Yahoo account when the theft occurred in August 2013 was affected.
 
Yahoo’s new Verizon-owned parent company, Oath, said the updated figure was reached after “new intelligence” was obtained and investigated with help from outside forensic experts.
 
“Verizon is committed to the highest standards of accountability and transparency, and we proactively work to ensure the safety and security of our users and networks in an evolving landscape of online threats,” Chandra McMahon, Verizon’s chief information security officer, said in a press release. “Our investment in Yahoo is allowing that team to continue to take significant steps to enhance their security, as well as benefit from Verizon’s experience and resources.”
 
Oath said it would begin notifying the additional 2 billion users who weren’t included in the last investigation over the course of the next several days.
 
The compromised information includes usernames, telephone numbers, dates of birth, hashed passwords (using MD5) and, in some cases, encrypted or unencrypted security questions and answers, an Oath spokesperson said on the company’s website. Payment card data and bank account information, however, were not part of the leak, the new investigation confirmed.
