Last weekend a leak was revealed data from 533 million accounts from Facebook. Much has been said about the risks and dangers of this information being publics, but how exactly did this leak occur? And what kinds of consequences for the platform can this bring?

First it is important to explain that this Facebook leak occurred in 2019, but the data has only been made public now. The main suspicion is that this information was being sold by hackers before they were made available entirely in a forum.


O Olhar Digital talked to Felipe Guimarães, CEO of LGPDY, a digital security company. The expert explained a little how this type of failure occurs. “What happened was that Facebook released an update patch that left security holes. Hackers keep an eye out for moments like this to attack, this is common, ”he detailed.

Felipe still says that these data seem harmless, but in the hands of criminals they can be dangerous. “Most passwords involve dates of birth. If the hacker gets your information, he can draw a profile and even get access to other platforms with his login, ”he said.

The expert points out that a database of this size is a big dish for criminals, who can sell this information to other groups and companies or even use it to try to steal users.

“The Internet was not made to be safe, not least because the reasons for its creation were far removed from the problems we have today. However, due to the uses it has been given and the exponential increase in users worldwide, security measures have been adopted so that the data that travels in the digital environment does not suffer from issues related to breach of privacy ”, explains Adriana de Moraes Cansian, lawyer in digital law at Resh Cyber ​​Defense.

The responsibility in such a case rests entirely with the social network. However, although a data leak is not something new, even for Facebook itself, the scenario this time is quite different due to the volume of information that escaped the social network.

This could result in slightly more severe punishments for Mark Zuckerberg's social network. To date, the biggest such fine ever received by such a company has been Google, who was fined $ 50 million in France for “lack of transparency, incorrect information and lack of valid consent in personalized advertising”.

Felipe explains that the expectation in the midst of digital security is that Facebook “handily exceed” that value. The expert said that as the data was leaked in 106 countries and each nation has its own legislation, the company must face lawsuits in several courts around the world.

“All applications, whether websites or mobile applications, are subject to the General Data Protection Law - Law 13.709 / 2018 - obliged to keep the data they collect confidentially and securely because they are data controllers. More than that, they owe data subjects who collect evidence that what they say they do, in fact, is done with respect to security. Obligation that extends to the data sharing chain, which must also be transparent in the eyes of the holder ”, concludes Adriana.
