The once thought 8 character length password may no longer be safe, after the GPU-accelerated password recovery attack can break weak WPA/WPA-2 PSK passwords.
The Elcomsoft Wireless Security Auditor mentioned that its software can work completely off-line and find passwords by analyzing a dump of network communications, and display them in plain-text. The Wireless Security Auditor does require the source of a valid log of wireless communication.
Experts have urged IT managers to move from 8 character WMP passwords to 12 or 15, in a quote from David Hobson: "It's a wake-up call to IT managers, pure and simple. IT managers should now move to 12 and even 16 character keys as a matter of urgency. It's not very user-friendly, but the potential consequences of staying with eight character keys do not bear thinking about."
