San Francisco, Oct 13: Cyber attackers stole data from 29 million Facebook accounts using an automated program that moved from one friend to the next, the social media giant has revealed.
The Facebook had originally said up to 50 million accounts were affected in a cyber attack that exploited a trio of software flaws to steal "access tokens" that enable people to automatically log back onto the platform.
Facebook Vice President Guy Rosen told reporters that the FBI asked the company to limit descriptions of the attackers due to an ongoing inquiry, a report in ABC stated.
The hackers, whose identities are still a mystery, accessed the names, phone numbers, and email addresses of 15 million users, he said, adding for another 14 million people, the attack was potentially more damaging.
Although Rosen did reveal that while the attackers' intent has not been determined, they did not appear to be motivated by the upcoming US mid-term Congressional election on November 6.
Facebook said it would message affected users over the coming days to tell them what type of information had been accessed in the attack. UNI
