This is the real reason for Facebook user data leak

 A few days ago, the data of 533 million Facebook users was leaked on the internet. The data included their profile names, Facebook ID numbers, email addresses, and phone numbers.

Facebook said in its initial response that the data had been leaked in 2019. The security patch of the bug that leaked the data was released by the company in August of that year.

Although Facebook has tried to generalize this news by linking it to an old incident, the recent incident has presented a bleak picture of the overall security sector. The data first appeared on the Criminal Dark Web in 2019. But at the time, Facebook did not elaborate on the incident.

But just two days ago on Tuesday, Mike Clark, Facebook's project management director, admitted in a blog post that the incident had taken place.

But the dilemma here is that there are many cases of data breach and exposure of Facebook. It is unknown at this time what he will do after leaving the post.

Is it the Breach incident that was exposed by security firm UpGuard in April 2019, exposed by a third party, or the millions of data that hackers released before Facebook changed its policy in 2018? Or is it an incident reported by TechCrunch in September 2019 or related to a third-party data-sharing scandal involving Cambridge Analytica in 2018?

But during the investigation, it has come out that the data that has been made public recently is not related to any of the above incidents. Facebook has admitted that the huge 533 million data that was made public five days ago on Tuesday's blog is a different dataset without being linked to the previous incident.

The hackers misused an error in Facebook's address book contacts import feature to gain access to such large data.

Although Facebook said it had made the patch available for vulnerability in August 2019, it is uncertain how many times it had been abused before.

The data, which includes more than 530 million Facebook users in 106 countries, includes Facebook IDs, phone numbers, Facebook's initial user Mark Zuckerberg, US Transport Secretary Pete Buttingig, and European Union Commissioner for Data Protection Didier Renders.

The latest data on the high-profile list of victims in Birch includes 61 from the US Federal Trade Commission and 651 from the Attorney General.
