Most of you might have watched the TV series 'Numb3rs'. In one of those episodes they were discussing about how to capture the contents on the screen of a computer using just an antenna. Now I don't remember in which episode it was. But I am curious to know whether such scenarios possible practically? Please add that episode name If anyone remembers it. |

I didn't see the episode, but it may be referring to "Phreaking", by which the signals from a CRT monitor can be listened-in on (it uses high frequency changing currents to display the information, so these will inevitably result in some RF radiation from which this information can in principle be extracted). Wikipedia article has a bit more info. |
