Personal data more than 500 million users of the social platform Facebook were posted on a hacking forum in early April.

These last months, confidential data leaks on large sites are multiplying. No one is safe from this kind of hacking.

The data exposed includes personal information of some 533 million users of the social network in 106 countries, including more than 32 million in the United States, 11 million in the United Kingdom and 20 million in France, specifies the American website dedicated to the economy and finance.


A hack that dates back to 2019


Facebook said:

“This data comes from a leak that dates back to 2019 and has been resolved,” said Mike Clark, a director of the social network in a statement.

“It should be understood that the malicious actors obtained this data not by hacking our systems but by looting them on our platform before September 2019”, indicates the person in charge of Facebook. “This practice often relies on automated software to extract public information from the internet which can then be distributed on forums like this.”

So if the hacking is old, the information collected in 2019 may still be up to date. Your mail address or your phone number could still be used for hackers in 2021.
