It's exactly what Mem5 told. The workaround is using cd to the installation folder.

My favorite way to brute-force using a non-english charset is using a pipe. It therefore works only for slow hashes! If you want to BF in utf8 as described above you can do: 1. Make a charset file in...

Sure not, as I said. You need to install Intel OpenCL runtime for CPU, this gives you a much better performance for AMD CPU (and also faster than pocl).

The first one is the typical empty hash in LM, so useless because not used. The second one is the NTLM, you can try to crack it with -m 1000.

There's not much to say in terms of error message. This error occurs if the self-test hash was not cracked but it should be cracked. That's all we know.

Typically the nvidia driver should install it's own opencl runtime, but for some reason it did not. Another question is why is there an AMD opencl runtime detected. Maybe the computer had an AMD GPU i...

A good rule of thumb is that if you have more than 500kH/s of total performance (all OpenCL devices), hashcat brain (even running on a very fast system) will create a bottleneck. Another rule to add i...

The high CPU use on startup is because of the kernel compilation. This is done by the opencl runtime which is provided from the opencl device driver. It creates some initial CPU load only for a short ...

The password output given by hashcat is based on the crackpos. IOW, if the crackpos is wrong, the password is wrong, which is not the case. If you want to know more about the details, see here: htt...

Yes, per salt. But salts are always known, otherwise the original authentication system can not do its work either.

Don't forget to -O, with a mask of length 11 you will get a drastic performance increase.

Post: RE: Crackpos incorrect

You cannot measure the efficiency of the attack based on crackpos as this is a parallel execution with millions of workitems in it. It is up to the OpenCL runtime which one to execute in which order.
