Although 311,127 Australians were affected by the Cambridge Analytica data breach, only 53 of the country’s citizens took the Facebook quiz responsible for improperly obtaining and using personal information, as reported by The Guardian. Similarly, 63,724 people in New Zealand were affected, but only 10 New Zealanders downloaded the quiz.
It’s reasonable to assume many of the people in Australia and New Zealand were impacted via a friend in their own country, but that’s likely far from accounting for everyone. These numbers also demonstrate the ripple effects from users’ friends abroad who granted permissions to the personality quiz app, called “thisisyourdigitallife.”
As many as 87 million Facebook users may have had their information compromised, including more than 1 million people each in the UK, Philippines, and Indonesia. Facebook is now displaying a link at the top of the News Feed, which points people to remove apps they no longer need. Users can also visit a page on Facebook’s help center that will tell you if you or a friend was affected and what information was potentially shared.
Facebook is now implementing platform changes to prevent something similar from happening again in the future — including looking for “suspicious activity” from developers in order to audit them — after making similar changes back in 2014. Today, Facebook CEO Mark Zuckerberg is testifying before Congress to answer questions about his company’s use and protection of user data.
