WPA Wireless Security Crackable

This isn't breaking news, but WPA (Wi-Fi Protected Access), a fairly beefy security protocol used to secure wireless networking, is not immune to being cracked. If a weak, short passphrase is used, an attacker only has to capture a relatively small amount of wireless traffic, and then crack it offline. Use random passphrases with a mix of upper and lowercase characters and symbols, and use at least 20 characters. You can even store the key in an encrypted text file and simply copy and paste it when you need to use it. And don't think hiding your SSID and filtering MAC addresses is enough.
