Yeah, hacking is just taking something and tinkering with it to make it do something that it's not really designed to do, isn't it? This can sometimes be useful and fun, but can obviously also be done for malicious purposes, and that's sometimes referred to as "cracking" and the ones who do it as "crackers".
Wait a second. They use a 3rd party wireless card, and he said in the end that "the flaw is not in the Apple operating system as we used 3rd party hardware". I'd say that's quite different from the impression I got from reading the macrumors headline here. A default MacBook using the built in Airport isn't vulnerable as far as I can tell.
He also said that the exploit isn't as trivial as a generic buffer overflow. Now, to exploit a generic buffer overflow, you need to have a certain level of l337ness to begin with, so that means you don't have to worry about your neighbour braking into your wireless network, just yet. Unless someone releases premade tools to do the exploitation, I'd say that normal people and small businesses don't have to worry at the moment.
