Hashcat - newbie advice needed - s4m - 09-04-2022
Hello, I am having problem with cracking my own wi-fi network. Password has 11 characters and i made a custom list of chars that contain all characters needed in a plain text format with extension hcchr as it says in the documentation.
I used hcxdumptool for catching the handshake in .pcapng format and converted it to hc22000 for hashcat.
When I run the command
"hashcat.exe -a 3 -m 22000 --session pause -1 chars.hcchr hash.hc22000 ?1?1?1?1?1?1?1?1?1?1?1"
it works fine but when it finishes I get Exausted status, the output is below:

processed pcapng files................: 1
I also removed all data that is not related to my own wifi from the file.
What am i doing wrong? All chars needed are in the file "chars.hcchr" so i'm confused why dont hashcat simply bruteforce the pass for wi-fi. Any help appreciated
RE: Hashcat - newbie advice needed - slyexe - 09-06-2022
Because your capture file has several other hashes included with it. Whether your wifi was actually captured we cannot say.
In hashcat:
Recovered........: 0/4 (0.00%) Digests
This shows 4 different hashes are being attacked.
In hcxpcapngtool:
PMKID written to 22000 hash file.........: 19
States theres 19 pmkids captured and processed into your attack file.
So isolate your mac address of your device when you capture with hcxdumptool or just pull it from your capture file with a text editor and try an easier bruteforce since you KNOW the password.
RE: Hashcat - newbie advice needed - s4m - 09-06-2022
Thanks for your answer, much appreciated.
That's exactly what I did, I edited the captured file and deleted everything that has nothing to do with my wi-fi network, leaving only the entries which contained my MAC address (4 entries were with my MAC address). From your answer, the only thing that comes to my mind is that I did not capture the PMKID of my network or the file is corrupt, although during the capture period I created traffic (disconnecting and connecting clients, surfing the net...). And regardless of everything, I got the "status : Exhausted"
I'll try again to capture the file, let it run longer perhaps, and see how it goes.
RE: Hashcat - newbie advice needed - ZerBea - 09-07-2022
To make sure hashcat is working as expected get both hc22000 example hashes from here
https://hashcat.net/wiki/doku.php?id=example_hashes
and store them into sample.hc22000

I did everything as you suggested, Hashcat works as it should, I got passwords for both files. The only thing left is that the dump file is bad. I caught a new dump file again, so I'm going to start over. Thank you very much for the suggestions, they helped me a lot. When I succeed, the question is when, not if
, I will poste the success and share it with you. Thank you again and I wish youall the best.
RE: Hashcat - newbie advice needed - s4m - 09-08-2022
It turns out that I had a typo in "chars .hcchr". I was so convinced that I put all the characters in the file that I didn't notice that when changing the password for this test I made a mistake in entering a number instead of a letter which I usually do and for some reason now I didn't . If anything, I look at things on the positive side, the mistake allowed me to better understand and learn about Hashcat, but I finally succeeded. Maybe for a new beginner, this can be a lesson on how not to waste a lot of time on a small typo
Best regards, hashcat-newbie.
