Love the way the Guardian article smoothly segues between "bloke is impersonated on facebook" page to:

"The sophistication and relentlessness of these "advanced persistent threat" cyber attacks has convinced intelligence agencies on both sides of the Atlantic that they must have been state-sponsored. Nato has warned its top officials about the dangers of being impersonated on social networking sites, and awarded a £40m contract to a major defence company to bolster security at the organisation's headquarters and 50 other sites across Europe."
