When people download a film from Netflix to a flatscreen, or turn on web radio, they could be alerting unwanted watchers to exactly what they are doing and where they are.
Spies will no longer have to plant bugs in your home - the rise of 'connected' gadgets controlled by apps will mean that people 'bug' their own homes, says CIA director David Petraeus.
The CIA claims it will be able to 'read' these devices via the internet - and perhaps even via radio waves from outside the home.
Everything from remote controls to clock radios can now be controlled via apps - and chip company ARM recently unveiled low-powered, cheaper chips which will be used in everything from fridges and ovens to doorbells.
The resultant chorus of 'connected' gadgets will be able to be read like a book - and even remote-controlled, according to CIA CIA Director David Petraeus, according to a recent report by Wired's 'Danger Room' blog.
Petraeus says that web-connected gadgets will 'transform' the art of spying - allowing spies to monitor people automatically without planting bugs, breaking and entering or even donning a tuxedo to infiltrate a dinner party.
