Facebook Data Breach in 2021 : 1.5 Billion User Data Has Been Stolen

Another flaw in Facebook’s systems was exposed by experts. A private research company uncovered that a hacker site had over 1.5 billion FB user profiles for sale. Concerned consumers can utilize internet tools to see if they are affected by the Facebook Data Breach 2021.

In the previous few days, Facebook has had a lot of issues. It just experienced a power outage, which knocked off all of its internet-connected services (Facebook, WhatsApp, Instagram, and Oculus). The corporation is also facing legal action after a whistleblower said it is putting “its own interests, such as earning more money,” ahead of user well-being.

Experts are now expressing their newest concern over Facebook’s user data security and privacy. Privacy Affairs, a private cybersecurity business, performed the study.

1.5 Billion User Data Has Been Stolen

According to TechRepublic, 1.5 billion Facebook user records were discovered for sale on the internet. With about 3 billion registered users on Facebook, this means that half of the platform’s overall population had their data stolen.

The stolen information was recovered via scraping publicly accessible data from Facebook user accounts. Malicious actors may have harvested data using bot tools such as plugins and quizzes.

Miklos Zoltan, Founder of Privacy Affairs explained to TechRepublic,

“Every time someone enters one of these (Facebook) surveys or quizzes, they permit the creators of these games to view their personal Facebook information, they permit the creators of these games to view their personal Facebook information,” 

Privacy Affairs compared the seller’s data sample to all known Facebook leaks and found no matches. However, upon closer inspection, the data looked to be genuine. This indicates that new and legitimate Facebook data has been taken.

Data such as Facebook user IDs, names, email addresses, locations, gender, phone numbers, and other personal information was sold online. Malicious actors can use this data to phish, swindle, spam, intercept messages, and even try a hack on the victim’s account.

Because of Facebook’s initiative, the sale post was taken down as of Wednesday (October, 6 2021). However, it is unclear at this time if the information would be uploaded or abused on another hacker website.
