This isn’t even the biggest data mishap the company has been caught up in.
The news: A security researcher discovered a database pulled from Facebook that contained over 419 million phone numbers. The data included Facebook IDs and in some cases names, genders, and countries. Because the server hosting the database wasn’t password-protected, anyone could find and access it, according to Sanyam Jain, the researcher who passed his discovery on to TechCrunch. It’s unclear who pulled the information from Facebook’s systems or why, but presumably it must have been an employee to have that level of access.
Who was affected? The exposed server included 133 million records from US-based Facebook users and 18 million UK users. Another had over 50 million records from users in Vietnam. Unfortunately, there is currently no way to check if your data was among the leaked records.
