WPA-Personal and WPA2-Personal remain vulnerable to password cracking attacks if users rely on a weak password or passphrase. WPA passphrase hashes are seeded from the SSID name and its length; rainbow tables exist for the top 1,000 network SSIDs and a multitude of common passwords, requiring only a quick lookup to speed up cracking WPA-PSK.

The following example shows IP addresses that might be used with an office network that consists of six hosts plus a router. The six hosts addresses are:
In 2010, researchers from the University of Pennsylvania investigated the possibility of cracking a device's password through a smudge attack (literally imaging the finger smudges on the screen to discern the user's password). [27] The researchers were able to discern the device password up to 68% of the time under certain conditions. [27]
