From Wired News: "
Wireless networks are a little less secure today with the public release of "AirSnort," a tool that can surreptitiously grab and analyze data
moving across just about every major wireless network.
When enough information has been captured, AirSnort can then piece together the system's master password.
In other words, hackers and/or eavesdroppers using AirSnort can just grab what they want from a company's database wirelessly, out
of thin air."
