Facebook applies in the case of an already known data security span the salami tactic: So far, the company spoke of tens of thousands of users concerned, now it becomes clear: The passwords of millions of users of the photo platform Instagram were stored unencrypted on internal servers. The company said Thursday.

Facebook had admitted in mid-March that the passwords of hundreds of millions of users of various platforms had been stored in unencrypted form on internal servers. Users of the Facebook Lite app, millions of Facebook users and tens of thousands of Instagram users were affected.

The corporation emphasized at the time that the passwords had never been visible to outsiders. Also, there is no evidence that employees have abused her.

Facebook has been shaken by a series of scandals. Among others, it was found that the data of approximately 87 million users had landed at the data analysis company Cambridge Analytica. Among other things, they should have been used illegally in the past US presidential campaign for the campaign of today's incumbent Donald Trump.

Only this week, a new data protection gap was also known. As the magazine "Business Insider" reported, since May 2016 Facebook has collected the e-mail contacts of some new users without asking for permission. Facebook announced on Wednesday that it may have "unintentionally" uploaded the email contacts of up to 1.5 million newly registered users. It is a data collection of unknown magnitude.
