Mask error? - logistix - 01-25-2012
I created a .txt file as my dictionary with the word panthers in it and then use the ?d?d mask to crack the known WPA password of panthers77 successfully. However, when I try the .txt file with the word panthe in it with a mask of ?l?l?d?d it get exhausted. What am I doing wrong?

hey ho.. i cant reproduce this locally, see my tests:

but maybe its related to wpa kernel. you can give me the .hccap so that i can reproduce it with wpa? please also tell me driver version you are using
RE: Mask error? - logistix - 01-25-2012
I emailed you the .hccap file. I am using 11.12 drivers on a 5870 but sometimes use 2 6770's. I used the GUI 0.5.0 and then chose the oclHashcat-plus tab. Thank you for looking into this!
RE: Mask error? - logistix - 01-26-2012
I am also getting the same exhausted behavior with the command line:
c:\hashcat\oclHashcat-plus-0.07>oclHashcat-plus64.exe --hash-type 2500 --attack-mode 6 --outfile c:\hashcat\oclHashcat-p
lus-0.07\12345678.FOUND.txt --gpu-devices 2,3 c:\hashcat\oclHashcat-plus-0.07\12345678.hccap C:\hashcat\oclHashcat-plus-
0.07\12345.txt ?d?d?d
The dictionary .txt file has only 12345 in it and the ?d?d?d mask should try appending the rest of the numbers. The known password is 12345678 and it works successfully with bruteforce and dictionary attacks. The .cap file can be found in the aircrack-ng folder and converted to .hccap to do testing.
RE: Mask error? - atom - 01-26-2012
excellent find. i can confirm its a bug. i was able to reproduce this locally and i have already fixed it.
it occours in -a 6 when the base word side is < length 8, because oclhashcat-plus rejects them since in WPA the plain must be at least of length 8. Of course this is a bug, because it has to add the length of the modifier side. you can see this here:

Thanks again for reporting!
here is a quote of the fixed version:

Glad to hear this bug has been fixed. When can I download the new version 8?
