Facebook says users should exercise caution when adding applications. But a malicious program, masquerading as a harmless application, could potentially harvest personal data. The popular social networking site allows users to add a variety of applications to their profile. Personal details of Facebook users could potentially be stolen, the BBC technology programme ‘Click’ has found.

Or at least that is the implication, and it also lets you keep your details private from the rest of the world. Facebook is the darling of the moment, allowing friends to stay in touch, post photos, and share fun little games and quizzes.

Facebook has said that any programs which violate their terms will be removed, but lets face it, millions of applications are added every minute by thousands of users, imagine how long it would take to go through them all.
