An anonymous reader writes "A article on The Register titled talks about a demo that was given in London last month by NCC Group where they turned a modern TV into an audio bug. 'The devices contain microphones and cameras that can be utilized by applications — Skype and similar apps being good examples. The TV has a fairly large amount of storage, so would be able to hold more than 30 seconds of audio – we only captured short snippets for demonstrations purposes. A more sophisticated attack could store more audio locally and only upload it at certain times, or could even stream it directly to a server, bypassing the need to use any of the device’s storage.' Given the Snowden revelations and what we've seen previously about older tech being deprecated, how can we protect ourselves with the modern devices (other than not connecting them to the Internet)?"
