Security researchers have uncovered more instances of Facebook user data being publicly exposed on the internet, further underscoring its struggles as it deals with a slew of privacy problems.
The researchers from the firm UpGuard said in a blog post Wednesday that the data, which included user names and passwords, came from two different Facebook apps that stored their data publicly on Amazon‘s cloud services. Facebook says the databases have been taken down.
But the episode illustrates Facebook’s issues with controlling its users’ data, especially once it is in the hands of third-party developers.
The databases were from a Mexico-based media company called Cultura Colectiva, which included more than 540 million records — like user comments and likes — and from an app called At the Pool.
