The personal data of Facebook users are shared with other platforms and in the Amazon cloud storage, Bloomberg reported.

“In one instance, Mexico City-based digital platform Cultura Colectiva, openly stored 540 million records on Facebook users, including identification numbers, comments, reactions and account names,” the source noted.

The data of another 22 thousand Facebook users, including names, passwords, email addresses, were available in the already non-existing At the Pool application. UpGuard specialists explained that they do not have data on how long they were stored in the application, as the base was closed on April 3 after Bloomberg reported a leak to Facebook, and the social network warned Amazon.

Facebook has already faced leaks as the British analytical company Cambridge Analytica has already collected user data through its application on Facebook and used it to place political advertisements, in particular, during the presidential campaign in the US and Brexit. The intervention could affect a total of 87 million users of the social network.

Cambridge Analytica denied its fault, claiming that it was a normal and legitimate data collection for online advertising. After that, the company lost all customers and filed for bankruptcy. Facebook founder Mark Zuckerberg claimed responsibility for the data breach.
