I recently got a new laptop. As I usually do, I removed the wifi module from it, since I intend to use it in public places such as my college and I don't need any sort of connectivity outside my home.
The reason I do this is because there is no physical switch for the wireless connection on the laptop and I feel insecure if it is simply disabled via software. Several friends and relatives have told me I may be too paranoid since obviously 'you can't do anything to a laptop if the wifi connection is turned off'.
I've always been of the 'You not knowing about it doesn't mean it isn't possible' opinion, so I'd rather be safe than sorry, but this sparked my curiosity about this issue.
Has anyone successfully attacked a computer via wireless while it was disabled via software? What are the risks of having a wifi module inactive but installed and powered?
