GCHQ's targeted tools against individual smartphones are named after characters in the TV series The Smurfs. An ability to make the phone's microphone 'hot', to listen in to conversations, is named "Nosey Smurf". High-precision geolocation is called "Tracker Smurf", power management – an ability to stealthily activate an a phone that is apparently turned off – is "Dreamy Smurf", while the spyware's self-hiding capabilities are codenamed "Paranoid Smurf".

Those capability names are set out in a much broader 2010 presentation that sheds light on spy agencies' aspirations for mobile phone interception, and that less-documented mass-collection abilities.

The cover sheet of the document sets out the team's aspirations:

Some of my ideas to protect your privacy

1. Never say anything that you wouldn't want overheard anywhere near that phone.
2. Be aware that the state can listen to anything your are talking about. That is if you are making a call or not.
3. Be aware that the state can track all your movements with that smart phone.
4. All websites you visit are logged and your emails saved.
5. If you've got something private to talk about. Don't discuss it anywhere by that smart phone. A good place would be somewhere outdoors.
6. Even if the smart phone is 'switched off' don't believe that they still can't monitor you.

It has also been suggested that the state can monitor you from your landline phone. Think about it that phone has a microphone on it and it's permanently connected to the phone exchange.
