Cambridge Analytica’s Aleksandr Kogan Wants You To Know He’s Not A Bad Guy (HBO)

The Cambridge University researcher at the center of the Facebook data scandal has appeared before a British parliamentary committee investigating fake news.

Aleksandr Kogan was working for Cambridge University when he designed a personality testing app which gathered the data of tens of millions of Facebook users.

That data was passed on to political consultancy Cambridge Analytica without user consent, and is alleged to have been used to try and influence voters in the 2016 U.S. presidential election. Kogan told VICE News that he believes a copy of that data is still available, even though Kogan and Cambridge Analytica assured Facebook it had deleted the data. Kogan has said he deleted the data.

“I mean I lost my career for sure,” Kogan told VICE News. “Like It’ll be very difficult for me to ever be an academic anywhere.”

Since being branded a liar by Facebook for his role in the affair, Kogan has been on a road to try and clear his name.

VICE News joined Kogan before — and after — his visit to Britain’s parliament.

Christopher Wylie: The Whistleblower Who Exposed Cambridge Analytica’s Facebook Scam (HBO)

LONDON — Christopher Wylie played a big role in building one of the most effective political weapons of the digital age. Now he’s trying to make amends.

The 28-year-old London-based Canadian is defying a non-disclosure agreement to blow the whistle on his former employer Cambridge Analytica, the controversial political analytics firm known for its work on Donald Trump’s presidential campaign in the U.S. and Uhuru Kenyatta’s in Kenya. He says the U.K.-based company, which he helped found in 2013, has built a powerful software program to predict and influence the choices of voters by using data harvested from 50 million leaked Facebook profiles.

The data was collected by an app called thisisyourdigitallife, owned by the Cambridge-based academic Aleksandr Kogan, which was downloaded by about 270,000 people. Users were paid to take a personality test, which they were told would be used for academic research. They might not have known that it also harvested information on their Facebook friends, creating a vast data set that was ultimately sold by Kogan to Cambridge Analytica.
