The British Government Still Has No Idea Who Is Using the Facebook Data Cambridge Analytica Stole

Almost three years after Facebook was first alerted to a potential data breach committed by Cambridge Analytica, it is unclear how many people still have access to the data stolen by the company. The findings come in a report released Tuesday by the Information Commissioner's Office, a government agency in the UK that reports to Parliament. The investigation, which launched in May 2017, analyzed over 50 million pages of data seized from the now-defunct Cambridge Analytica. According to interviews with Cambridge Analytica employees, multiple attempts were made to delete the Facebook data misused by the company, but there still might be ad targeting tools that are based on data harvested by Facebook that have not been deleted. Facebook first learned of data leaks in 2015 when The Guardian reported Cambridge Analytica's involvement with Ted Cruz's presidential campaign.
