Noob trying to follow this walkthrough

[soronrheeyi]

Hi all,

I am trying to crack my own wifi and have successfully saved a .hccapx file  and am following this tutorial

I am to the point where I am running this command: hashcat -m 2500 -a3 tctsom.hccapx ?d?d?d?d?d?d?d?d --force

(tctsom is my network name and the title I renamed my file). I have to use --force because I get this error: Device #1: Not a native Intel OpenCL runtime. Expect massive speed loss.
             You can use --force to override, but do not report related errors.


When I run the command without --force.

However when I run with --force, I get this error: tctsom.hccapx: No such file or directory

My question: where is this file? I thought it would be in /etc/shadow ... apparently not. I am logged in as root on The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) and have the file saved in multiple locations... downloads... desktop...

I am missing something obvious, but I don't know what...

hashcat doesn't magically find the file for you on your system. Give the full path if it's not in your cwd.

What does this have to do with /etc/shadow at all?

[freeroute]

If you don't know where the tctsom.hccapx is.
Find the file:
"find / -type f -name tctsom.hccapx"

With hashcat use the full path to your tctsom.hccapx file.

Thanks, you're right. Once I identified the correct file path I was able to make progress ... The /etc/shadow location was from a separate tutorial I was trying to follow.

Thanks. I now have another issue below, which results in a segfault:

Code:

hashcat -m 2500 -r /usr/share/hashcat/rules/best64.rule /usr/share/hashcat/tctsom.hccapx rockyou.txt --force

Can someone point me in the direction of an a-z tutorial for a new hashcat user? I'm not getting where I am going wrong on each step here.

Pentium CPU is your problem.
Try again on a GPU?

[undeath]

Don't use --force and report resulting problems on here. Fix your problems.

Ok. What is the main problem? Or point me in the direction of a useful tutorial, please.

thank you! However here are the specs for my system and I thought the GPU was supported: https://www.intel.com/content/dam/www/pu...-vol-1.pdf

[undeath]

Well, remove --force and see what problems hashcat reports and fix them?!
