Facebook removes exposed user records stored on Amazon’s servers

Facebook Inc said on Wednesday that it removed public databases containing its user data on Amazon.com Inc’s cloud servers after cybersecurity firm UpGuard discovered millions of exposed records.

UpGuard’s Cyber Risk team announced in a blog post on Wednesday that Mexico City-based news website Cultura Colectiva had used Amazon servers to openly store 540 million records on Facebook users, including identification numbers, comments, reactions and account names.

Another database, from an app called At the Pool, listed names, passwords and email addresses of 22,000 people, UpGuard said.
