Facebook director Mark Zuckerberg today revealed that all its 2.2 billion users must assume that their public data has been compromised by third-party scrapers.

The source of this vulnerability is the search function of Facebook, that allows everyone to search for users via their email address or phone number. Users must sign up for this, via an option that lets your name appear in the search queries. But the security settings have enabled this option by default.

Call

During a call with members of the press, Zuckerberg indicated how open Facebook left its users: “ I would have gone if you had that setting your public information in some way.

Incidentally, he indicates that it is his mistake. People just make mistakes. And if they had just done this, something else would probably have gone wrong.
