New user help - oclHashcat wont start attack - JimmyW - 06-13-2014
Using HashcatGUI v.0.40 and cudaHashcat 1.21, I tried brute force an NTLM hash, 6-10 chracters, lower case and digits. The program started fine, but never progressed. It proceeded through the startup with no errors, snd then hung at the command prompt, where I could check status, quit, etc. Eventually, it "Exhausted." I'm running Win 7x64 with 3 GTX480 cards, and my drivers are v337.88. I would attach screenshots, but the Forum won't accept them (JPGs), perhaps because this is my first post. Thanks.

copy/pasting terminal output is always preferred over posting screen shots. at a minimum you should at least post the command line you used.

Thanks for the advice. In the GUI, using brute force, I selected the hash file that contained one NTLM hash. Charset=?l?d, Mask=?l?l?l?l?l?l?l?l. Length=6-8, Accel=64. At that point. I invoked I started hashcat, and this is the terminal output. I'm starting to think that hashcat operated properly, given my mask:

I think that I see my mistake: the mask. It includes ?l, but I specified ?l?d. If I don't enter a mask, it seems to run okay. If I don't use a mask, I presume each character can be ?l of ?d. Thanks!

Well if it "Exhausted", it means nothing was found, not that it didn't work.
