Facebook trims victims of data breach to 29m
FACEBOOK says cyber attackers used an automated program that moved from one friend to the next to steal data from 29 million of its user accounts and not the 50 million profiles it initially reported.
The company says it will message those affected over the coming days to tell them what type of information has been accessed.
The breach has left users more vulnerable to targeted phishing attacks and could deepen their unease about posting to a service whose privacy, moderation and security practices have been called into question by a series of scandals.
The attackers took profile details such as birth dates, employers, education history, religious preference, types of devices used, pages followed, recent searches and location check-ins from 14 million users. For the other 15 million users, it was restricted to name and contact details.
Facebook cut the number of affected users from its original estimate after investigators reviewed activity on accounts. Still, cyber-security experts warned that the millions of users were at risk of attack.
“The bottom line is that all this data is still out there,” Armor Inc cyber-security researcher Corey Milligan said.
