multicapconverter - all in one tool - s77rt - 10-22-2020

Hi,

multicapconverter is a portable python tool that you can use to convert your capture file to any of the hashcat supported formats.
it was mainly based on the cap2hccapx tool, with more features added such as pcapng support and much more listed below

Code:
usage: multicapconverter.py --input capture.cap --export
                            {hcwpax,hccapx,hccap,hcpmkid,hceapmd5,hceapleap}
                            [--output capture.hcwpax] [--all]
                            [--filter-by filter-by filter]
                            [--group-by {none,bssid,essid,handshake}]
                            [--wordlist wordlist.txt] [--do-not-clean]
                            [--ignore-ie] [--ignore-ts] [--quiet]
                            [--update-oui] [--locate] [--version] [--help]

Usage Examples

We have a capture file 'capture.cap' which includes 4 handshakes:

+---+-------------------+----------+---------------+
| # |      BSSID      |  ESSID  | AUTHENTICATED |
+---+-------------------+----------+---------------+
| 1 | 00:00:00:00:AA:AA | Wifi    | N            |
+---+-------------------+----------+---------------+
| 2 | 00:00:00:00:AA:AA | Wifi    | Y            |
+---+-------------------+----------+---------------+
| 3 | 00:00:00:00:BB:BB | Internet | Y            |
+---+-------------------+----------+---------------+
| 4 | 00:00:00:00:CC:CC | Wifi    | Y            |
+---+-------------------+----------+---------------+


By default the original c version write all the hccapx into one file no matter what. If you need a single separated handshake you will have to use a hex editor and take the required 393 bytes by yourself.. Well not anymore


Also the original c version export all the handshakes even if they are not authenticated, in this python version it's a bit different, as the default is to ignore unauthenticated handshakes but can be exported by using the --all flag



1) Extract each handshake into a separated file (Auth Only)

Code:
python3 multicapconverter.py -i capture.cap --group-by handshake -x hccapx

...

Output hccapx files:

00-00-00-00-AA-AA_0.hccapx // 2

00-00-00-00-BB-BB_0.hccapx // 3

00-00-00-00-CC-CC_0.hccapx // 4



2) Extract each handshake into a separated file (All)

Code:
python3 multicapconverter.py -i capture.cap --group-by handshake -x hccapx --all

...

Output hccapx files:

00-00-00-00-AA-AA_0.hccapx // 1

00-00-00-00-AA-AA_1.hccapx // 2

00-00-00-00-BB-BB_0.hccapx // 3

00-00-00-00-CC-CC_0.hccapx // 4



3) Extract all handshakes into one file (just like the old c version)

Code:
python3 multicapconverter.py -i capture.cap --group-by none -x hccapx --all

...

Output hccapx files:

capture.hccapx // 1, 2, 3 and 4



4) Extract handshakes based on BSSID

Code:
python3 multicapconverter.py -i capture.cap --group-by bssid -x hccapx --all

...

Output hccapx files:

00-00-00-00-AA-AA.hccapx // 1 and 2

00-00-00-00-BB-BB.hccapx // 3

00-00-00-00-CC-CC.hccapx // 4



5) Extract handshakes based on ESSID

Code:
python3 multicapconverter.py -i capture.cap --group-by essid -x hccapx --all

...

Output hccapx files:

Wifi.hccapx // 1, 2 and 4

Internet.hccapx // 3



6) Extract handshakes based on ESSID having a specific BSSID

Code:
python3 multicapconverter.py -i capture.cap --group-by essid --filter-by bssid 00:00:00:00:CC:CC -x hccapx --all

...

Output hccapx files:

Wifi.hccapx // 4



Miscellaneous
  • Extract wordlist 
    --wordlist wordlist.txt
  • Update OUI Database 
    --update-oui
  • Locate networks locations 
    --locate
Notes
  • Time Gap is in microseconds

  • --group-by works only for hccap and hccapx output

  • --all works only for hccap, hccapx and hcwpax (WPA*02) output

  • --locate and --update-oui works only if -q/--quiet is not set

  • by default, if a capture have both WPA*01 and WPA*02 (hcwpax format), WPA*02 will be ignored on the exportation process. If you want to export both, use --do-not-clean

  • by default, multicapconverter ignores packets with zeroed timestamps. If you want to process such packets, use --ignore-ts (Not Recommended)

  • by default, multicapconverter exports only pmkids that are PSK/PSK256 related (AKM check). If you want to ignore AKM check, use --ignore-ie (Not Recommended)

Extra


If you are using Linux and you want to use the tool from different places (instead from only the working directory), simply copy the python script to your bin path:

Code:
sudo cp multicapconverter.py /usr/bin/

sudo chmod +x /usr/bin/multicapconverter.py

sudo ln -s /usr/bin/multicapconverter.py /usr/bin/multicapconverter

Now you can simply use multicapconverter, example: [ICODE]multicapconverter -i capture.pcapng -x hcwpax[/ICODE]


TIPS
  • use --quiet for better performance

RE: multicapconverter - all in one tool - s77rt - 04-26-2022

New version available. v1.2.0
  • - Added an option to overwrite ESSID tags (useful for cloaked ESSID)
  • - Set default export option to hcwpax
  • - Removed mac geolocation lookup

RE: multicapconverter - all in one tool - ZerBea - 04-26-2022

Great improvement.

BTW:
Now, there is an issue report regarding unset/zeroed SSID IE_TAGS in BEACON frames:

Thanks,
Yeah i have been following on the discussion going on hcxtools

RE: multicapconverter - all in one tool - ZerBea - 04-27-2022

Only the capturing tool sees what's going on, on a WiFi channel. Packets which are not recorded or filtered out by the capturing tool are lost forever (the demo cap submitted on multicapconverter git confirm this). Neither multicapconverter, nor hcxpcapngtool nor other conversion tools will be able to bring this packets back.
