Did your data leak from Facebook? The site allows people to find out if they are among half a billion victims Average

PALO ALTO (USA) Over the weekend, it emerged that more than half a billion people had leaked some sensitive data from Facebook profiles. If a person has a profile on this social network, with this number there is up to a 20 percent chance that it was just him. But now a tool has emerged that will allow users to see if they were among the 533 million damaged.


More than 500 million users leaked personal data to Facebook years ago. It has now appeared on the Internet and, according to experts, can be exploited by hackers. This is another example of a possible lack of security of user data on this social network, the AP agency said on Sunday.

The Bussines Insider server was the first to report the release of this data, according to which 533 million users from 106 countries had private data. These are telephone numbers, full user names, geolocation data, e-mail addresses or dates of birth.

Server CNN pointed out that there is a tool that can be used to verify whether someone’s data has really leaked. This is a website haveibeenpwned.com (Has anyone attacked my account?). So far, it works somewhat limited only by entering an e-mail address linked to a Facebook profile. The author of the article tried to enter his e-mail and the server informed him that his data had actually leaked.

It even offers an overview of all data leaks in which his account figured. These include, for example, the data leak of the Polish video game company CD Projekt Red, which is behind the game hits Zaklínač and Cyberpunk 2077. In June 2016, data leaked to about 1.9 million people.

Facebook's move in Australia has caused embarrassment.

Among other things, the portal offers advice on how to really secure your account. CNN points out that Facebook itself has not made it easy to verify whether data from specific accounts has been stolen or leaked. Entering an email address in the HaveIBeenPwned portal is still a limited tool for detecting an attack, because not all users have been stolen email.

Tool creator and security expert Troy Hunt said on Twitter that the affected accounts will soon be searchable using a phone number. The vast majority of leaked information about specific people contained a telephone number. Hunt pointed out that if you’re using Facebook, the statistical probability is about one in five that they just attacked your account.

The leak could provide valuable information to cybercriminals to impersonate strangers on the Internet, according to Business Insider Alon Gal of cybersecurity firm Hudson Rock, who alerted the leak on Saturday.

“These are old data that were reported in 2019,” Facebook said in a statement, according to the AP. “We detected and fixed this issue in August 2019.”
