Reports surfaced last month that Zuckerberg planned to testify before Congress after he said in a statement that Cambridge Analytica got data gathered from a personality quiz app created in 2013 by Cambridge University researcher Aleksandr Kogan. The app, which was installed by about 300,000 people, asked users to share their data as well as the data of their friends, Zuckerberg said. Friends did not know that their data was being shared with the app.
“Given the way our platform worked at the time, this meant Kogan was able to access tens of millions of their friends’ data,” Zuckerberg said.
He noted that Facebook implemented measures in 2014 to prevent similar situations and better protect user privacy.
Authorities with the Federal Trade Commission confirmed last month that the agency had opened an investigation into Facebook’s privacy practices.
