MNA Tech Desk: Facebook revealed on Friday that up to 50 million accounts were breached by hackers, dealing a blow to the social network’s effort to convince users to trust it with their data.
The social network is investigating the extent of harm done when hackers exploited a trio of software flaws to steal “access tokens,” the equivalent of digital keys that enable people to automatically log back into the social network.
Facebook chief executive Mark Zuckerberg said engineers discovered the breach on Tuesday, and patched it on Thursday night.
“We don’t know if any accounts were actually misused,” Zuckerberg said. “This is a serious issue.”
As a precaution, Facebook is temporarily taking down the “view as” feature—described as a privacy tool to let users see how their profiles look to other people.
