Phone number security breach for Facebook

Phone number security breach for Facebook

Social networking giant is in the headlines once again for privacy breach issues– this time concerning users’ phone numbers. In a bid to encourage two factor authentication, Facebook asks users to supply their mobile phone numbers should they have problems logging in.
However, security researcher and New York Times columnist Zeynep Tufekci has since revealed that our phone numbers are being used for other means.

Specifically, other users can now search for profiles by entering mobile phone numbers. Users cannot prevent this from happening, but they can change the settings to ensure only their friends can look them up with this information.
