Cambridge Analytica harvested 87 million Facebook users' data without consent for political targeting
Mar 17, 2018Data scientist Aleksandr Kogan's app 'This Is Your Digital Life' collected data from 87 million Facebook users (70.6M in US) without explicit consent in 2013-2014. Data sold to Cambridge Analytica and used for psychographic profiling in 2016 Trump and Cruz presidential campaigns. Facebook learned of misuse in 2015 but only asked for deletion without verification. Whistleblower Christopher Wylie exposed scandal in March 2018. Resulted in $5B FTC fine (largest ever privacy penalty), $100M SEC fine, Mark Zuckerberg Congressional testimony. Evidence showed targeted voter suppression of Black voters. Facebook misled investors about risks for 2+ years despite knowing about breach.
