Social media platforms and person data leaks aren’t any strangers to one another. Hackers usually exploit a vulnerability to scrape data, and typically, sheer abuse occurs by seemingly legit shoppers. Remember the Facebook-Cambridge Analytica scandal? Well, Facebook is once more on the middle of one other large data leak that has seen the private info of over half a billion users making its means online. As per a report by BusinessInsider, the data of over 533 million users – which incorporates particulars similar to telephone quantity, electronic mail handle, job data, and date of delivery to call a few – was put up on the market online. And later, it was shared freely on the internet.
“The exposed data includes personal information of over 533 million Facebook users from 106 countries, including over 32 million records on users in the US, 11 million on users in the UK, and 6 million on users in India. It includes their phone numbers, Facebook IDs, full names, locations, birthdates, bios, and – in some cases – email addresses.”
Details embrace:
Phone quantity, Facebook ID, Full identify, Location, Past Location, Birthdate, (Sometimes) Email Address, Account Creation Date, Relationship Status, Bio.
Bad actors will definitely use the knowledge for social engineering, scamming, hacking and advertising and marketing.

BusinessInsider claims to have verified the leak by matching sure Facebook person telephone numbers with the identification quantity within the leaked data set, and in addition verified the e-mail addresses utilizing the password reset characteristic. Liz Bourgeois, who’s Director of Strategic Response Communications at Facebook, tweeted the leaked data originated from a vulnerability that was fastened again in 2019.
Old data? Yes. But how usually do you modify the quantity and electronic mail linked to your Facebook profile?
Though the leaked data is likely to be two years previous, even when 1% of affected users nonetheless have that telephone quantity and electronic mail handle linked to their Facebook profile, the quantity of users whose private data was leaked stands at over 5 million. And I’m being a little too optimistic right here, since a majority of social media users aren’t too cautious with regards to the safety of their private data and don’t even use critically essential instruments similar to two-factor authentication.
This is previous data that was beforehand reported on in 2019. We discovered and glued this concern in August 2019.

Coming again to the Facebook leak, the data – regardless of being two years previous – can nonetheless be exploited for a selection of assaults, starting from hacking and phishing to spamming. And the worst half is that your entire dataset was posted online on hacking boards without spending a dime, which implies for those who knew your means round data, you’ve got a treasure trove of details about half a billion Facebook users.
Alon Gal, CTO of cybercrime intelligence agency Hudson Rock, found the leaked data of Facebook users being offered, and later shared publicly. “Users having their personal information leaked is a huge breach of trust,” Gal was quoted as saying. Troy Hunt, creator of the HaveIBeenPwned database, says the leak is legit and he has already uploaded the leaked electronic mail addresses to the HaveIBeenPwned database the place you’ll be able to confirm in case your private data was additionally leaked. Chances are excessive that it was!
But for spam based mostly on utilizing telephone quantity alone, it’s gold. Not simply SMS, there are heaps of companies that simply require a telephone quantity today and now there’s lots of of hundreds of thousands of them conveniently categorised by nation with good mail merge fields like identify and gender.

And even when the proportion of users whose telephone quantity was leaked stands at 20%, the quantity continues to be substantial. Plus, the telephone numbers within the leaked dataset additionally include the nation codes neatly organized, which implies it may be abused by malicious events on a regional foundation to a variable extent. Aside from standard spamming, there are a ton of shady companies on the market that may abuse these hundreds of thousands of leaked telephone numbers in numerous elements of the world.
The leaked data is in every single place
Of course, there are a lot of cybersecurity specialists and common users on the market who’re asking questions in regards to the large leak. Will Facebook take accountability? Is the social media big going to inform users that have been affected by the users? What steps users ought to take if their electronic mail and telephone quantity have been leaked? The dangers of focused assaults are excessive, particularly given the huge scale and international attain.
Hunt notes that the leaked Facebook person data shouldn’t be solely obtainable on hacking boards, however can also be circulating collectively on social media platforms. “This data is everywhere,” he provides. While Facebook ought to be made to reply in regards to the large leak, the least that the corporate can do for its humongous person base is notify affected users, and it positively has the assets to take action. A easy notification shall be sufficient, for starters!
