The personal information of 5 billion Facebook users may be hacked



According to a report on Saturday by Business Insider, the phone numbers and personal information of one billion Facebook users may be stolen and posted online, an unprecedented security breach.

Large amounts of data are uploaded to online forums used by hackers. According to reports, it includes email addresses and biographical information.

Alon Gal, the co-founder and CTO of Hudson Rock, a private cybercrime intelligence company, first published information about the data breach on social media platforms such as Twitter and LinkedIn in the early hours of Saturday morning. He shared a screenshot showing an online marketplace where Telegram users requested 533 million records using modified account names.

“This means that if you have a Facebook account, the phone number used by that account is most likely to be leaked,”

; Gal wrote on Twitter.

If each record represents a Facebook user (according to Business Insider), this means that approximately 19% of the personal information in the social media giant’s 2.8 billion personal data has been leaked. Gal said that more than 32 million leaked records came from the United States.

According to “Business Insider” reports, user information has been posted on the “low-level hacker forum.”

Menlo Park social media company did not immediately respond to the Chronicle’s request for comment.

According to a report by Business Insider, the first batch of records was obtained in 2019 due to software “vulnerabilities.” The online news outlet said it verified the leak by matching the phone numbers of known Facebook users with the leaked data.

Scammers and identity thieves may use stolen personal information.

Facebook has been the subject of past security breaches, including a security breach involving the British company Cambridge Analytica, in which the personal information of approximately 50 million Facebook users was sold to and used in the 2016 presidential election of Donald Trump and Senator Ted Cruz.
