Facebook has placed a page online that allows users to check if their data has been leaked to Cambridge Analytica. The company also sends alerts to users who have fallen victim to the data breach.
These users do not have to look up the page themselves; who has the making with the datalek, receives a notification from Facebook about this. Facebook does not indicate what any subsequent steps might be.
On Monday it became known that in the Netherlands up to 90,000 Facebook users have been leaked data. This data was used by data analysis company Cambridge Analytica to make profiles. On Tuesday evening, Mark Zuckerberg is questioned about the matter by the US Senate.
