Head of MI6 outed on Facebook

It's a story that could have appeared in the 1960s spy spoof "Get Smart". Confidential and personal details about the new head of Britain's MI6 have been leaked to the public on Facebook.

The guilty party? His own wife, who didn't bother checking Facebook's privacy settings, and went about merrily exposing to the world all the details of their personal life - including information that rival spy networks usually have to work hard to learn.

Not everybody is as naive and stupid as Lady Shelley Sawers. But it's a timely reminder to check the privacy settings on all your social networks. You might be exposing more than you intended!
