Researchers Turn Home Wi-Fi Router Into Spy Device

hypnosec writes "Researchers at University College of London have applied principles of radar used in defense and designed a detector using home based Wi-Fi routers to spy on people across walls. Using the principles behind the Doppler effect ... Karl Woodbridge and Kevin Chetty, at University College London, have built a prototype unit that uses Wi-Fi signals and recognizes frequency changes to detect moving objects. The size of the prototype unit is more or less the size of a suitcase. The unit contains a radio receiver comprising of two antennas and a signal-processing unit. The duo carried out test runs and ... they managed to determine a person's location, speed, and direction (even through a one foot thick brick wall). The device could be used to spot intruders, monitor children or the elderly, and could even be used in military applications."

Now I have to run Wild Weasel missions against my own router.

Ok, it can be used to detect if you are about to be attacked by zombies or RIAA agents.

So cheating with wallhacks is bad? Not for a christian -- Jesus abused an item cloning bug [wikipedia.org] himself.

Finding new ways to spy on people is something we seem to be really good at here in the UK

On the plus side, James Bond ends up with an ample supply of new gadgets to show off.

At any rate, since he shared the bread and fishes with all on the server, I wouldn't call it abusing the bug, especially since they were all just idling anyway, there wasn't a match in progress at that time.

Some other cases of him exploting glitches also come to mind. But being a son of the server admin, I don't think there was any chance of him getting banned...
