Known WPA2 hash cannot be found - ben0wilson - 04-22-2012

I have been looking all over for the best way to crack a WPA2 hash. I have tried aircrack, but that doesn't have GPU acceleration, I have tried pyrit (which is great) but that doesn't run on windows, then I came across hashcat and I have great hope for it, but for some reason it cannot find a known key out of a WPA2 hash.

I got the hash from the Wireshark website: http://wiki.wireshark.org/SampleCaptures -> Induction.pcap sample

I then conformed it to .hccap and also made a sample password list including the password: [ Induction ].

When I ran it through hashcat-plus, it ran fine, but came up with 0/6 rejected and nothing found.

I know many people come on here complaining about known hashes not working and this is due to the password being under 8 or over 15 characters (I've done my research). But I have no explanation for this.

I tried it in aircrack and it got it successfully which is the part that's so confusing. Is the original .pcap file invalid for hashcat, am I doing something else correctly. Help would be appreciated. Smile

hashcat has its own cap format:: .hccap
use this online-converter:: http://hashcat.net/cap2hccap/
just cracked it ; )

Code:
Coherer:Induction

Status.......: Cracked

Input.Mode...: Mask (Inductio?l)

Hash.Target..: Coherer

Hash.Type....: WPA/WPA2

Time.Running.: 2 secs

Thanks for the quick response! Unfortunately I had already done that. I'm sorry if I did not make myself clear. I had already converted to .hccap format. I have tried a wordlist, I have tried masks, and I still can't get it.

My steps:
1. download .pcap from wireshark wiki
2. convert to .hccap on hashcat converter
3. load hashcat-gui x64 openCL
4. Mode: Brute-Force; Mask: Inductio?l; Hash type: WPA/WPA2
5. Start
6. be unhappy. :/

whats ur command line??

RE: Known WPA2 hash cannot be found - ben0wilson - 04-22-2012

oclHashcat-plus64.exe --hash-type 2500 --attack-mode 3 C:\aa-Ben\files\hacks\WiFi\SSIDs\Induction.hccap Inductio?l

RE: Known WPA2 hash cannot be found - M@LIK - 04-22-2012

looks fine.. just tried it again..
so whats the result u get?? screenshot??

RE: Known WPA2 hash cannot be found - ben0wilson - 04-22-2012

like i said, something is weird...

(2 pics should be attached)

The issues I can think of:
1. some settings issue somewhere
2. Running 0.5.1, need 0.7?
3. faulty download that's missing a file that allows program to run, but not find the file.

I think I'm going to try reinstalling...

RE: Known WPA2 hash cannot be found - M@LIK - 04-22-2012

hmmm... the last four things i can say is::
1- move the .hccap file to the program's directory.
2- run this command directly no GUI (in the oclHashcat-plus's directory)

Code:
oclHashcat-plus64 -m2500 -a3 Induction.hccap Inductio?l

3- if it doesn't work try to re-convert the cap file and rename it to something else.
4- in the GUI it says gpu temp. watchdog:90 while in the command prompt it says temp. watchdog disabled >> bigger problema : |

and no hashcat-gui v0.5.1 has oclHashcat-plus v0.071 already

Thank you for your help, but this is still an unanswered problem. Anyone else able to give it a shot!?!?

Guess you are just using a wrong catalyst version or you have or had the SDK installed or your hardware is defect.
