540 Mllion Facebook Records Leaked from Public Amazon S3 Buckets

More than 540 million Facebook user records were exposed through publicly accessible Amazon S3 buckets used by two third - party apps to store user data such as passwords, account names, user IDs, interests, relationship status, and more.

As the UpGuard Cyber Risk team discovered, Mexico - based media company Cultura Colectiva stored records of approximately 540 million of its users in a 146 GB database called "cc - datalake," stored in a misconfigured Amazon S3 bucket that gave permissions to anyone download.

This large collection of Facebook files contained "comments, reactions, accounts, FB IDs and more," which enabled Cultura Colectiva to "set an algorithm to predict what content will generate the greatest circulation."

Another database related to the now - defunct Facebook - integrated "At the Pool" app (an archived version of the HERE website) with only 22,000 was also found by UpGuard in a downloadable S3 bucket, but unfortunately this one also contained user passwords in plain text.
