Facebook has changed its user settings, allowing its developers to request access to a user’s contact address and phone number.
The move has alarmed a number of privacy advocates who believe that this feature could be exploited by rogue applications on the world’s largest social networking platforms.
Sophos security expert Graham Cluley wrote on his personal blog: "My advice to you is simple: Remove your home address and mobile phone number from your Facebook profile now. While you're at it, go through our step-by-step guide for how to make your Facebook profile more private."
A Facebook spokesperson said in a statement to Fox News: “We want to make it easy for people to take the information they've entered into Facebook with them across the web. This new permission gives people the ability to control and share their mobile phone number and address with the websites and apps they want to use.”
