All Yahoo Accounts Compromised In 2013 Security Breach

Every single account on Yahoo was affected in a 2013 security breach.

Verizon, which just acquired Yahoo, says all three billion user accounts were compromised in the attack.

Names, birth dates, phone numbers and passwords were all stolen.

Yahoo didn’t disclose the attack until last year when it said only one billion accounts were affected.

Yahoo says it will now alert the users that were not previously contacted.
