They still got you.

Quote:If you've got a wireless keyboard or are working on a laptop unplugged from the wall, which would make this attack useless, fret not: The hackers have a method for eavesdropping on you too. A simple laser beam -- better than a laser pointer, but not by much -- can be pointed a shiny object on the table where the computer sits, and the beam's reflection is captured by a receiving system. The vibration of that reflection caused by the striking of keys can be analyzed and, as with the electrical outlet system described above, reconstructed into words, since every key produces a unique vibration pattern. All this technique requires is a direct line of sight to the PC and a few hundred dollars worth of equipment.
