Security researchers today said they found data on 540 millions of Facebook users on Amazon's cloud servers.
Security researchers from the team UpGuard Cyber Risk, reported today that they found a total of 146GB data on Amazon's cloud servers, split into two large pieces. The first piece of data comes from a media company called Cultura Colectiva and contains records of user activity such as comments, reactions, friends, interests, groups, checkins, events, photos and more, as well as account names and identifiers Facebook.
The second part of the leak appears to be a backup of a third-party application embedded in Facebook called "At the Pool", which contained the same information as the previous part plus user passwords. However, the researchers said that the passwords appear to come from the "At the Pool" application, instead of Facebook accounts.
However, users who have used the same passwords on both their accounts, Facebook and the "At the Pool" application, risk losing their accounts. The researchers also said that the data was removed after contacting Facebook.
The At the Pool application stopped 2014 and the company website is currently returning an 404 error notification. This means that exposed names, passwords, emails, Facebook IDs and other details were open to each attacker for an unknown period of time.
Therefore, the security company recommends to all Facebook users, especially those who have used the application "At the Pool", to immediately change their passwords. Just a few weeks ago, engineers Facebok discovered that user names and passwords of hundreds of millions of users were kept as plain text on one of their servers and accessible to thousands of employees.
