Yahoo hack steals personal info from at least 500M accounts

SAN FRANCISCO — Computer hackers swiped personal information from at least 500 million Yahoo accounts in what is believed to be the biggest digital break-in at an email provider.

The massive security breakdown disclosed Thursday poses new headaches for beleaguered Yahoo CEO Marissa Mayer as she scrambles to close a $4.8 billion sale to Verizon .

The breach dates back to late 2014, raising questions about the checks and balances within Yahoo — a fallen internet star that has been laying off staff and trimming expenses to counter a steep drop in revenue during the past eight years.
