Facebook Inc. said Cambridge Analytica has agreed to an audit by a digital forensics firm to determine whether the advertising-data company still has information on 50 million Facebook profiles it said had been deleted.
Aleksandr Kogan, the researcher who originally obtained the data via the social network and allegedly shared it with Cambridge Analytica, has also verbally agreed to an audit, Facebook wrote Monday in a blog post. Cambridge, which worked for U.S. President Donald Trump during the 2016 campaign, was required to destroy the information in 2015 when Facebook learned it had the data, but reportedly failed to do so. Cambridge has denied wrongdoing.
“If this data still exists, it would be a grave violation of Facebook’s policies and an unacceptable violation of trust and the commitments these groups made,” Facebook said. “We are moving aggressively to determine the accuracy of these claims.”
Digital forensics firm Stroz Friedberg will conduct a “comprehensive audit,” and Cambridge Analytica will provide “complete access to their servers and systems,” Facebook wrote.
