The 146 gigabytes of data was found by UpGuard’s Cyber Risk team, as it was stored openly on an Amazon S3 bucket, and besides the 540 million records, it also included another database from an app called At the Pool, which listed names, passwords and email addresses of 22,000 people.
In September 2017 for example it found the CVs of thousands of former US military personnel, including hundreds with ‘Top Secret’ security clearances, were left available on an Amazon S3 cloud storage repository.
Then in November 2017 UpGuard found “critical data” belonging to the US army on virtual image of hard disk left on an AWS server, without password protection.
Indeed that data was deemed so sensitive that it is not even allowed to shared with America’s allies.
The researchers found that Mexico City-based news website Cultura Colectiva had used Amazon servers to openly store 540 million records on Facebook users.
“One, originating from the Mexico-based media company Cultura Colectiva, weighs in at 146 gigabytes and contains over 540 million records detailing comments, likes, reactions, account names, FB IDs and more,” it wrote.
