"Companies have been concerned for years that they might get hacked. Now, they're also worried about getting whacked.

Whacking is wireless hacking, usually done by a person who's in the right place at the right time with the right kind of radio transceiver. By whacking, an intruder can tap into private communications going across almost any wireless network."
