"The best information we have suggested that no European user data was shared by Dr. Kogan with Cambridge Analytica. This is backed up by the contracts Dr. Kogan’s company GSR had with Cambridge Analytica; it is backed up by Dr. Kogan’s testimony on the subject; it’s backed up by our own internal analyses. Now we won’t be able to conclusively confirm this until we conduct a forensic audit of Cambridge [Analytica] which we plan to do as soon as we are authorized by the UK Information Commissioner’s Office," Satterfield said.
Satterfield stated that Facebook, as a result of the Cambridge Analytica's actions, is investigating all apps which had been storing large amounts of user data since 2014.
"We are investigating every app that had access to large amounts of information before we changed our platform in 2014. Where we have concerns we will suspend the app and where we conclude the data was misused we will ban the app completely and tell everyone affected. So far we have investigated thousands of apps and suspended more than 200," Satterfield said.
Satterfield added that in handling the Cambridge Analytica case, the company had followed European data protection law.
Facebook faced sharp criticism after it emerged in March that personal data of about 50 million of its users had been harvested by Cambridge Analytica without their permission through a special app designed by Alexander Kogan. The information was allegedly used to help target political advertising. In early April, Facebook estimated the number of users affected at around 87 million.
