Pixie attack against a pcap file?

[anode]

Title kinda says it all, but can you run the PixieDust attack against a pcap/4-way hasndshake file?

Or is it strictly WPS based?

[Sebkinne]

WPS only.

however, if you already have the 4way handshake, dump it to aircrack-ng, or convert its output and throw it at hashcat which can also break it with wordlist, or brute force on the fly(using GPU)

Hashcat is my goto.  But pixie is milliseconds, if its vulnerable.

(gonna poke around a bit, saw something that might lead somewhere.  I tossed the Q out there as to not reinvent the wheel if there was something already out there.)

WPA/2 = Aircrack-ng and oclHashcat FTW.
