Hundreds of millions of Facebook records exposed on public servers – report

More than 540m Facebook records were left exposed on public internet servers, cybersecurity researchers said on Wednesday, in just the latest security black eye for the company. Researchers for the firm UpGuard discovered two separate sets of Facebook user data on public Amazon cloud servers, the company detailed in a blogpost. One dataset, linked to the Mexican media company Cultura Colectiva, contained more than 540m records, including comments, likes, reactions, account names, Facebook IDs and more. The other set, linked to a defunct Facebook app called At the Pool, was significantly smaller, but contained plaintext passwords for 22,000 users. The large dataset was secured on Wednesday after Bloomberg, which first reported the leak, contacted Facebook.
