December 2018: Facebook comes under fire after a bomb report discovered that the company gave more than 150 companies, including Netflix, Spotify and Bing, access to unprecedented amounts of user data, such as private messages.
Some of these & # 39; partners & # 39; had the ability to read, write and delete private messages from Facebook users and to see all participants in a thread.
It also allowed the Microsoft search engine, known as Bing, to see the name of all friends of Facebook users without their permission.
Amazon was allowed to obtain the names and contact details of users through their friends and Yahoo could view streams of messages from friends.
Since last year, Sony, Microsoft and Amazon have been able to obtain all e-mail addresses of users through their friends.
September 2018: Facebook announced it was hit by its worst data breach ever, affecting 50 million users – including those from Facebook boss Mark Zuckerberg and COO Sheryl Sandberg.
Attackers used the & # 39; View as & # 39; function. of the site, with which people can see what their profiles look like for other users.

The unknown attackers have used a function in the code & # 39; Access tokens & # 39; to take over people's accounts, potentially allowing hackers access to private messages, photos & messages – although Facebook said no evidence had been provided.
The hackers also tried to collect personal information about people, including name, gender and place of residence from Facebook's systems.
Facebook said it does not yet know if information from the relevant accounts has been misused or used, and is working with the FBI to conduct further investigations.
However, Mark Zuckerberg assured users that there was no access to passwords and credit card information.
As a result of the infringement, the company logged approximately 90 million people out of their account as a security measure earlier today.
March 2018: Facebook made headlines earlier this year after data from 87 million users had been incorrectly accessed by Cambridge Analytica, a political consulting firm.
The disclosure has prompted government inquiries about the company's privacy practices around the world and has sparked a & # 39; # deleteFacebook & # 39; movement among consumers.
Cambridge Analytica communications company had offices in London, New York, Washington, as well as Brazil and Malaysia.
The company claims it can & # 39; find your voters and move them to action & # 39; through data-driven campaigns and a team consisting of data scientists and behavioral psychologists.
& # 39; In the United States alone, we have played a central role in winning presidential races and congress and state elections, & # 39; with data on more than 230 million American voters, Cambridge Analytica claims on its website.
The company benefited from a feature that meant apps could request permission to access your own data and the data of all your Facebook friends.

This meant that the company could extract the information from 87 million Facebook users, although only 270,000 people gave them permission to do so.
This is designed to help them create software that can predict and influence voter choices at the polls.

This information is said to have been used to help the Brexit campaign in the UK.
It has also had several previous problems.
In 2013, Facebook announced a software error in which 6 million phone numbers and email addresses of users were exposed to unauthorized viewers for a year, while a technical failure in 2008 revealed confidential birth data on 80 million Facebook user profiles.
