A laptop showing the Facebook logo is held alongside a Cambridge Analytica sign at the entrance to the London offices of Cambridge Analytica. The company's acting CEO, Alexander Tayler, is stepping down, and is the second CEO out since the data sharing scandal broke. The acting chief executive officer of Cambridge Analytica, the political data firm embroiled in controversy after improperly sharing data from some 87 million Facebook users, has stepped down.

Mark Zuckerberg's own personal data was taken as part of Facebook's data abuse scandal, he has said. He made the confession during Congress hearings, where US lawmakers quizzed the Facebook boss on how it was responding to claims it had unethically abused data about its users. The admission means that organisations may have access to data about Mr Zuckerberg that wouldn't usually be available to the public. Developers were able to access information like a users' friends and other personal information – a decision that has been criticised, and which Facebook has taken efforts to now stop. Mr Zuckerberg didn't say exactly what third-party app had stolen his data.

Senator John Thune has stated that the Senate Commerce Committee plans to hold a hearing on Cambridge Analytica and "similar firms" that might have obtained Facebook data without permission. There are "plenty of questions" about what Cambridge Analytica did, Senator Thune said. There's no estimated timetable for the hearing. Whenever a hearing happens, Cambridge Analytica's response is likely to be familiar: it'll fight tooth and nail to assert its innocence. The company recently posted an article attempting to dismiss the "speculation and hearsay" surrounding data sharing, including its assertions that it and its data partner GSR obeyed the law when collecting and handling Facebook users' info.

BBC journalist Katie Hile has discovered that she's one of the millions affected by the Facebook-Cambridge Analytica data scandal.

There are three basic categories of response. That's great news, but Facebook is still investigating other companies, so don't do a celebration dance just yet, because more news is likely coming. There's also a chance that you downloaded and used the This Is Your Digital Life app through which researchers were able to directly collect data. If this is the case, all of the people with whom you were friends around 2015 were also affected. The final option is the message pictured above.

This week, Facebook began notifying people whether they had ever logged in to the "This Is Your Digital Life" app -- which has been linked to the exposure of tens of millions of records for political research. This week, Facebook began notifying people whether they had ever logged in to the "This Is Your Digital Life" app -- which has been linked to the exposure of tens of millions of records for political research. Facebook users have begun to see whether they're among the 87 million people whose information may have been compromised for use by a political research firm. For some, the news is good: "It doesn't appear your Facebook information was shared with Cambridge Analytica." The notifications are appearing on Facebook's page about users' exposed data.

Facebook began alerting some users that their personal information was accessed during the Cambridge Analytica data breach, and suffice to say, Facebook users aren't happy. Some 87 million people are estimated to have possibly been affected by the Facebook Cambridge Analytica data breach, a higher number than the social media giant originally anticipated. Last week, Facebook announced that users who may have had their data misused by Cambridge Analytica would get a detailed message via their News Feed on Monday. Facebook has said most of the affected users are in the U.S., though there are over a million each in the Philippines, Indonesia and the U.K. Now users are taking to social media to reveal whether or not their personal information was obtained during the data breach, screen-shotting their Facebook notification. "Facebook sold me out to Cambridge Analytica too," one user wrote on Twitter.

Facebook CEO Mark Zuckerberg will testify at two Capitol Hill hearings this week over the Cambridge Analytica scandal, and we asked our tech reporter why that matters. Facebook CEO Mark Zuckerberg (center) walks out of Sen. Dianne Feinstein's office after their meeting on Capitol Hill. WASHINGTON -- Facebook CEO Mark Zuckerberg is testifying for the first time ever before Congress on Tuesday as he attempts to apologize for high-profile privacy breaches at the social media giant and convince doubtful lawmakers that he can fix the problem without government intervention. Zuckerberg is trying to restore public confidence after recent revelations that data from up to 87 million Facebook users was shared with Cambridge Analytica, a data mining firm used by the Trump campaign in the 2016 election. The information was shared without users' knowledge.

In the aftermath of the Cambridge Analytica scandal, you're probably wondering: Was I actually affected? After all, the company obtained data on 87 million users (that's the current estimate, anyway.) Facebook has, thankfully, started sending News Feed notifications to explain whether users' accounts were affected. If you're still waiting for yours to come through, however, you can visit this page and find out immediately. In short, it explains if you or your friends ever logged into This Is Your Digital Life -- the quiz app developed by university researcher Dr Aleksandr Kogan, which Cambridge Analytica used to profile and manipulate users.

It's an understatement that Facebook has found itself in some hot water lately in regard to data privacy, thanks to the Cambridge Analytica scandal. CEO and founder Mark Zuckerberg is testifying in front of Congress today and tomorrow in regard to the company's actions and the ways it has used personal data. Today, Facebook introduced the Data Abuse Bounty program, which will reward the social network's users for reporting apps that misuse data. If someone has proof or first-hand knowledge about an app violating Facebook's terms of service by collecting and transferring people's data to another party, whether for money, political influence or scams, they can notify Facebook through this program. If the tip pans out, Facebook will "shut down the offending app and take legal action against the company selling or buying the data, if necessary."
