o c/s using oclhashcat plus 0.09

[snooz]

I am using a HD 5870 card on Windows 7 64 bit using Catalyst 12.8. I am testing this on a WPA handshake I captured in airodump and converted to hccap using cap2hccap. I get the following output...

C:\Users\snooz\Desktop\oclHashcat-plus-0.09>oclHashcat-plus64.exe -m 2500 test.hcc

I suspect I've done something wrong because I keep getting 0 c/s and less than 50% utility of my GPU; sometimes the GPU will be at 0%. Is my command line missing something? Thanks.

Yes, it's missing a dict.

Yes, it's missing a dict.

Ah okay, so a dict is required? Thanks.

it does if you don't specify an attack mode. please read the output of ''oclHashcat-plus64.exe -h'' and then consult the wiki if you still do not understand.

In order to crack a WPA/WPA2 handshake, you need to have a dictionary and that is probably the only mode of attack which can give you success.

So, to complete your syntax:

oclHashcat-plus64.exe -m 2500 -a 0 test.hcc dict.txt

where, dict.txt is your wordlist.
