hccapx file not cracking - slawson - 08-27-2019
I used aircrack to capture a handshake of my network. I ran cap2hccapx to convert the file. I created a dictionary file with the password for the wifi. I ran hashcat64 -m 2500 -a 0 capture.hccapx dictionary.txt. Although I know the password is in the dictionary file, hashcat does not crack the password. I also ran a BF on the file, but it won't crack that way either.
What am I doing wrong?
RE: hccapx file not cracking - ZerBea - 08-27-2019
To answer what went wrong, we must take a closer look into the cap file. Please attach the cap file (zip compressed) and, if possible, some information about the tool which did the capturing.
RE: hccapx file not cracking - slawson - 08-27-2019
I used airodump-ng to capture the handshake along with the aireplay-ng -0 attack.
RE: hccapx file not cracking - ZerBea - 08-27-2019
Ok. Now we must follow the path from the content of the cap file up to the conversion to hccapx format. Therefore we need the cap file.
RE: hccapx file not cracking - slawson - 08-27-2019
Sorry, I thought I did that, but I didn't click the button. Here you go. I included the original cap file and the converted hccapx file.
RE: hccapx file not cracking - ZerBea - 08-27-2019
Thanks. The cap file is ok and contain a complete handshake M1, M2, M3 and 4xM4 (zeroed SNONCE). cap2hccapx converted it correct.
Additional the M1 contain a valid PMKID and you can run hashcat -m 16800 against it.
Next step is to make sure, OpenCL and/or CUDA isn't broken.
What GPU do you use? What driver is installed?
Also you can try the attached PMKID against your dictionary. Is the key recovered?
RE: hccapx file not cracking - slawson - 08-27-2019
I have two AMD R9-290X installed in my system. I am using Windows 10. I do get an error that OPENCL kernel self-test failed. Since I am cracking other password hashes, I guess I ignorantly assumed it would be ok to run it anyway.
My driver version is from 7/30/19 26.20.13001.25001
RE: hccapx file not cracking - ZerBea - 08-27-2019
Ok, lets see if you're up to it:
Please download example 2500 hash from here:
https://hashcat.net/misc/example_hashes/hashcat.hccapx
Password: hashcat!
copy password to your wordlist and run hashcat against it
Is the password recovered?
You can test also hashmode -m 16800 running the wordlist against this PMKID

Password: hashcat!
Is the password recovered, too?
RE: hccapx file not cracking - slawson - 08-27-2019
Still no recovery. Should I be looking in the direction of a driver problem?
