Not 50 million but nearly 87 million Facebook users were exposed by Facebook to Cambridge Analytica for data harvesting and misuse.
Facebook Inc. said that data on as many as 87 million people, most of them in the U.S., may have been improperly shared with research firm Cambridge Analytica.
This is Facebook’s first official confirmation of the possible scope of the data leak, which was previously estimated at roughly 50 million in news reports. About 270,000 people downloaded a personality quiz app and shared information about themselves and their friends with a researcher, who then passed along the information to Cambridge Analytica, in a move that Facebook says was against its rules.
