Facebook CEO Mark Zuckerberg today revealed that all of its 2.2 billion users should assume their public data has been compromised by third-party scrapers.
The source of this vulnerability is Facebook’s search function, which allows anyone to look up users via their email address or phone numbers. Users have to opt into it, via an option that lets their names come up in searches. The security settings have this option on by default.
