Using massive computational resources, the attacker essentially cracks the encryption by making an extremely large number of educated guesses as to what key is being used to secure the wireless data.

So brute force is the key and it takes a real whooper of a system to pull it off.

For some strange reason, I'm not too worried about this.
I don't think anyone sitting outside my house looking for a Wi-Fi connection is going to be able to hack my WPA protected network.

“I don’t think anyone sitting outside my house looking for a Wi-Fi connection is going to be able to hack my WPA protected network.”

Ditto - especially since most of my neighbors have no encryption at all.

No, what you quoted is the method that the new technique makes unnecessary. Read a few lines farther.

You don't need someone sitting outside of you house. If you have neighbors nearby chances are they can see you signal and can possibly use this technique.
