What's left to hack ?
no problem just have a computer not connected to the Internet problem solved right ?
Unfortunately even that can be hacked....https://en.wikipedia.org/wiki/Tempest_(codename

just leave your smart phone at home ....problem solved right ?
well no ...they can use wifi/mobile phone signals as a passive radar
your smart phone just acts like a aircraft transponder to these passive radars ...but if you don`t have a mobile they can still track you ok
How mobile phones let spies see our every move
Government's secret Celldar project will allow surveillance of anyone, at any time and anywhere there is a phone signalhttps://www.theguardian.com/uk/2002/oct/13/humanrights.mobilephones
Secret radar technology research that will allow the biggest-ever extension of 'Big Brother'-style surveillance in the UK is being funded by the Government.
The radical new system, which has outraged civil liberties groups, uses mobile phone masts to allow security authorities to watch vehicles and individuals 'in real time' almost anywhere in Britain.
The technology 'sees' the shapes made when radio waves emitted by mobile phone masts meet an obstruction. Signals bounced back by immobile objects, such as walls or trees, are filtered out by the receiver. This allows anything moving, such as cars or people, to be tracked. Previously, radar needed massive fixed equipment to work and transmissions from mobile phone masts were thought too weak to be useful.

The system works wherever a mobile phone can pick up a signal. By using receivers attached to mobile phone masts, users of the new technology could focus in on areas hundreds of miles away and bring up a display showing any moving vehicles and people.
An individual with one type of receiver, a portable unit little bigger than a laptop computer, could even use it as a 'personal radar' covering the area around the user. Researchers are working to give the new equipment 'X-ray vision' - the capability to 'see' through walls and look into people's homes.

yep time to invest in a magneto helmet
