It is not mandatory for hashcat and hcxtools/hcxdumptool.

RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - WPA_Catcher - 01-06-2020
Hi ZerBea
Thank you very much for all the work you have done on hcxdumptool and hcxtools they are fantastic tools!
I am only a keen hobbyist so please forgive my lack of computer skills but I am working my way through understanding just what is going on with your tools and the terms you use when writing on this forum.
Sadly my old hardware is no longer supported by hashcat so I am restricted to using hccap and not hccapx with all the wonderful new features it has. I am learning as much as I can about hccapx ready for when I have saved up enough!
Until I have built my... "Mega WPA Cracking Machine" and seek WIFI domination ...MMUUHHAAHA I have to use hccap. I have tried converting the output of hcxdumptool to hccap and it does produce a hccap file but it is not crackable.
I have converted my own network and was (NOT) able to break the known password. I did manage to convert to hccap(x) and use hashcat with cpu only to crack it though. The output size of the hccap is also much larger than expected.
I use hcxpcaptool --hccap-out=myfile.hccap (inputfile)
As explained I am only a keen hobbyist so I expect all this to be something I am doing wrong and so please accept my apologies in advance if it is my fault.
Also again this could be my fault but using hcxinfo I cannot seem to get an output to a text file when using "-o", I can however get an output to a text file by doing >>info.txt
Thanks for your time.
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 01-06-2020
Old hashcat is very, very limited regarding WPA. Additional we can have several issues within the conversion process (e.g. handshake is outside default nonce-error-correction of hcxpcaptool).
You can try latest hcxpcapngtool. I'm doing several things here better than in the old version.
But don't expect good/workable results on this ancient hccap format. wlanhcxinfo will not work on this format, too.
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 01-06-2020
hcxhashtool has now a build in test for PSK and/or PMK. To verify that you captured and converted the correct handshake do the following:
$ hcxpcapngtool -o test.22000 your_capfile_here.pcapng
$ hcxhashtool -i test.22000 --psk=your_PSK_here
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - WPA_Catcher - 01-06-2020
Thank you for your help.
I exported and converted the correct handshake so I don't think that was the problem.
I have attached a cap file (the old hashcat test cap from this site) and the resulting hccap file so you can see what happens. The password is hashcat!
I suggest if converting to hccap is not reliable then perhaps it might be time to remove the option to convert to hccap? I worry people may be working on hccap's which will never crack.
I understand I am in the minority needing to use hccap.
wlanhcxinfo was used on hccapx not hccap when I experienced the none output issue when using "-o"
The file extension for the attachment is .7z, I had to call it .txt because zipped attachments would not upload.
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 01-07-2020
Tested your example and it is working like a charm. The hccap file is ok!
This is the chain:
Step 1 convert hccap to hccapx (I'm not able to run ancient versions of programs, here)
$ wlanhc2hcx -o test.hccapx hashcat.cap.hccap
Step 2 run hashcat against hccapx
$ hashcat -m 2500 test.hccapx -a 3 'hashcat!'

Inside the hccap file are 15(!) single records, created by hcxtools. 1 is crackable, 15 not. This is the result of hcxtools nonce-error-correction (old hashcat can't do it, so hcxtools must do it) in case of an assumed packet loss during capturing.
As the hccap file is ok, your issue must be related to the old hashcat version.
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 01-07-2020
I suggest you to use latest hcxpcapngtool. It doesn't make nonce-error-corrections and provide only basic functions for conversion to old formats.
Pay attention: The cap file is synthetic and doesn't contain valid WPA/RSN information elements. The timestamps are zeroed. You must use option --ignore-ie to convert this cap file. Also you receive a warning about the timestamps.
$ hcxpcapngtool --hccap=test.hccap --ignore-ie hashcat.cap

RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - WPA_Catcher - 01-08-2020
Hi ZerBea
Sorry for my slow reply but I have been at work and I am learning about this stuff as I go so I am not as confident with my replies as I would like to be.
My old (I prefer the term vintage) hardware means I am restricted to hashcat v2.01
I tried your suggestion with hcxpcapngtool.
Obviously I did not re-convert to hccap(x) which is the step you noted I would not have to do and success it cracked! Thank you.
If you enjoy a technical challenge, which it seems like you do, is there any way to convert AP-Less captures to hccap? Obviously converting the EAPOL should be the same but there are no beacon frames with this method of capture. Is it possible for you to add the ability to make a hccap using the EAPOL parts and perhaps grab the ESSID from the probe request and pack into a hccap?
I noticed in the help of hcxpcapngtool the following:
bitmask for message pair field:
4: ap-less attack (set to 1) - no nonce-error-corrections necessary
I was not sure how to set a bitmask to see if my request was something already available.
With the new hcxpcapngtool will you be adding the option to allow the user to define mac_ap or mac_station of the target they wish to output as a hccap a bit like the options in wlanhcx2ssid?
A hcxdumptool question if you don't mind:
Using The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) (fully updated) and AlfaNetworks AWUSO36H running in virtualbox
I occasionally (not always) receive this error when trying to use hcxdumptool.
Code:
initialization...
could not create dumpfile Dump/wifidump_2020_01_08.pcapng
failed to init globals
hcxdumptool need full (monitor mode and full packet injection running all packet types) and exclusive access to the adapter
that is not the caseMy wifi card is in monitor mode and I try to run hcxdumptool first before anything else, if hcxdumptool produces the error I try wifite and airodump-ng which work properly. I use these just to check my card is in monitor mode. (I do not run anything else on the wifi when trying to use hcxdumptool).
The following is a simple script I use to get into monitor mode. Please could you tell me if there is there something I should add to my script to reduce the times I have trouble starting hcxdumptool?
Code:
#!/bin/bash
systemctl stop network-manager.service
systemctl stop NetworkManager.service
systemctl stop wpa_supplicant.service
wpa_cli terminate wlan0
airmon-ng check kill
rfkill unblock all
ip link set wlan0 down
iw wlan0 set monitor control
ip link set wlan0 upThanks again ZerBea, you are a wifi God
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 01-08-2020
Well, K*A*L*I isn't a distribution, which is easy to use. Why do I tell this first? Because of this error message:
"could not create dumpfile Dump/wifidump_2020_01_08.pcapng"
You simply haven't write permission to save the dumpfile.
By latest commit, I changed the warning to:
"hcxdumptool need full (monitor mode and full packet injection running all packet types) and exclusive access to the as well as write permission for the dumpfile"
This is an example of a script if hcxdumptool can't set monitor mode (e.g. on RTL8188, rtl8812 drivers, which require NETLINK):
Code:
#!/bin/sh
if test -z "$1"
then
for IFACE in `ls -1 /sys/class/net | grep ^wl`
do
printf "$IFACE "
cat /sys/class/net/$IFACE/address
done
printf "\nbitte WLAN-Adapter eingeben: "
read WLANDEV
else
WLANDEV=$1
fi
echo "deaktiviere Monitor für $WLANDEV"
sudo ip link set $WLANDEV down
sudo iw dev $WLANDEV set type managed
sudo ip link set $WLANDEV up
sudo iw dev $WLANDEV info
echo "aktiviere NetworkManager"
sudo systemctl start NetworkManager.service
sudo systemctl start wpa_supplicant.service"With the new hcxpcapngtool will you be adding the option to allow the user to define mac_ap or mac_station of the target they wish to output as a hccap a bit like the options in wlanhcx2ssid?"

The Linux philosophy (an mine, too) is:
Write programs that do one thing and do it well.
Write programs to work together.
https://en.wikipedia.org/wiki/Unix_philosophy
hcxdumptool -> WiFi part (fast without additional stuff, able to run headless)
hcxpcapngtool -> conversion (fast, without additional filtering stuff, able to run headless)
hcxhashtool -> provide filter / info about content of hashfile / pre-processor for hashcat/JtR
hcxpsktool -> provide information based on MAC and ESSID
wlancap2wpasec -> upload to data base
hcxwltool -> provide word list functions which other tools don't provide
All other hcxtools are deprecated and I'm going to remove them, soon (in sync with hashcat and JtR, when they drop old format).
Supporting and maintaining this ancient formats (hccap, hccapx, JtR old) is an is an immense effort.
Please take a look at the latest commit here:
