Facebook has exposed the phone numbers of 419 million users via an unsecured server, a security researcher has discovered. The massive leak affects 133 million users from the US, 50 million from Vietnam and 18 million from the UK. The leaked data also includes the unique Facebook account ID that the numbers are linked to. For some accounts, the name, gender and country of the user was also exposed.
