Over 540 Million Facebook User Records Were Found on Amazon Cloud Servers

Over 540 Million Facebook User Records Were Found on Amazon Cloud Servers

The second set (while not being as big as the first one) contained data backup of Facebook's in-app, dubbed At The Pool, and was found lying disclosed on Amazon's cloud-based storage, Amazon S3 bucket.

When Facebook was alerted about the issue of storing information on public databases, they worked with Amazon to take them down as reported by Bloomberg. Stored on Amazon was a trove of data that included names, email addresses and 22,000 users' passwords, according to UpGuard, which could not say how long that information had been left exposed.

Facebook didn't put the data there. But as these exposures show, the data genie can not be put back in the bottle.

It is also a punch in the eye for proponents of what many detractors call the "surveillance economy" where advertising and e-commerce is predicated on intelligence about users' every move and desire. "The data exposed in each of these sets would not exist without Facebook, yet these data sets are no longer under Facebook's control".

"The public doesn't realize yet that these high-level systems administrators and developers, the people that are custodians of this data, they are being either risky or lazy or cutting corners", said Chris Vickery, director of cyber risk research at UpGuard.

In the Cultura Colectiva dataset, which totaled 146 gigabytes, it was hard for researchers to know how many unique Facebook users were affected.

All the same information would be available to anyone that looked at those public pages, it added.

UpGuard said that the datasets vary in terms of when they were last updated, the data points present and the unique individuals in each.

At a size of 146GB, this AWS server stored over 540 million records detailing user account names, Facebook IDs, comments, likes, reactions, and other data used for analyzing social media feeds and user interactions.

Flip that board that says "It's been _ days since we found a massive pile of unsecured Facebook data" right back to zero, and get ready to reset your passwords again just to be safe.

At the same time, Facebook chief executive Mark Zuckerberg has embarked on a wholesale reimagining of the way users interact with each other on the social-networking site - and the data the company collects. While nobody could have predicted that their data would be stored in plain text and displayed for everyone to see, it's still a good idea to be careful of what you put on the internet and make sure to use different passwords for every service.
