Shoulder Surfing by Laserlight
Here’s the first sentence from the source document:
Using equipment costing about $80, researchers from Inverse Path were able to point a laser on the reflective surface of a laptop between 50 feet and 100 feet away and determine what letters were typed.
The gist of the article is that researchers were able to determine key sequences by analyzing the sound waves produced by each key as subjects type. The researchers have also managed to isolate EMI transferred through the power grid to identify keystrokes. Most folks need not worry about directed attacks of this nature, but if you’ve got a secret somebody wants badly, watch your back… and your windows.
