Telephone numbers, email addresses and other data from hundreds of millions of Facebook users have again been discovered in a hacker forum. Data tapping regularly becomes a problem for the network.

Once again, the data of many millions of Facebook users has been published unencrypted on the Internet.

TTelephone numbers, e-mail addresses and other data from hundreds of millions of Facebook users were discovered again in a hacker forum over the weekend. “This is old data that was reported back in 2019. We discovered and fixed the problem in August 2019, “wrote a spokeswoman for the online network on Twitter on Saturday. The IT security company Hudson Rock had previously discovered data from 533 million Facebook users online, as reported by the news site “Business Insider”.

When personal information such as email addresses and phone numbers circulate, the risk increases that people will fall for fake emails because they can be made more authentic. According to the latest information, Facebook has 2.8 billion users who are active at least once a month.

Scraping is always a problem for Facebook

As early as 2019, the phone numbers of 420 million users appeared online after a friend search function had been misused to access data. The telephone numbers were not openly visible, but could be called up on a large scale using automated inquiries – so-called “scraping”. This violated the Facebook rules, but was technically possible until the online network finally switched off the function. Once such data has been tapped, it can hardly be stopped from spreading on the internet.

Scraping has always been a problem for Facebook. In 2018, the online network had to admit that all publicly accessible data from the then more than two billion users was systematically collected through automatic retrieval. Later there were data protection debates about the company Clearview AI, which collected publicly visible images from, among other things, Facebook’s photo platform Instagram and on this basis compiled a database for facial recognition. Clearview AI customers include American law enforcement agencies.
