To extract passwords from .pcap files extracted with your Flipper Zero (or other tools), this is an "all-in-one" tool. You'll just need to follow these steps:

This is the CLI (Command Line Interface) version of my other script and repo flipperzero-GUI-wifi-cracker, i just wanted to make the process easyest as possible, and this is the result.

• Needed Tools
• Usage
  • For dictionary attack
  • For bruteforce attack
• PCAP Extraction
• Disclaimer

python3
hcxpcapngtool [included in hcxtools]
hashcat

git clone https://github.com/grugnoymeme/flipperzero-CLI-wifi-cracker.git
cd flipperzero-CLI-wifi-cracker
cd dictionary_attack
mv path/to/pcapfile.pcap path/to/flipperzero-CLI-wifi-cracker/dictionary_attack (optional) (if you not move it, specify the entire path when you'll be asked)    
mv path/to/yourwordlist.txt path/to/flipperzero-CLI-wifi-cracker/dictionary_attack (optional) (if you not move it, specify the entire path when you'll be asked)    
python3 dictionary_attack.py

• There are two different brute force script. One that run till the password is found, and the other in which you can set a timer that stop running the script if the password is not found in the time that you had set.

git clone https://github.com/grugnoymeme/flipperzero-CLI-wifi-cracker.git
cd flipperzero-CLI-wifi-cracker
cd bruteforce_attack   
// set the timer and the charset
python3 bruteforce_attack.py

• If you don't have a wordlist (password-list or a dictionary) to run the dictionary attack mode, you can easyly create one, executing these commands:

cd path/to/flipperzero-CLI-wifi-cracker
cd dictionary_attack (optional) (if you not create it, specify the entire path when you'll be asked)
nano wordlist.txt (and fill the file with all the possible passwords you want to try to find out the right ones)
^o (CTRL+o)
ENTER
^x (CTRL+x)
y (yes)
ENTER

(with Flipper Zero & ESP32 Marauder)

• You can simply upload the EAPOLwifiSniffer.json script into /ext/apps_data/marauder/scripts directory in your Flipper Zero and then you can directly run it through the [ESP32] Marauder application, under the Menu's voice "Scripts".

In alternative, if you want to do it yourself, because you need to modify the duration of the sniff, or the name of the script, or maybe adding some more stages or simply because you want to do it ALL by yourself:

• You can automatize the extraction of .pcap files from flipper zero, using the @0xchocolate 's companion app, of the @JustCallMeKoKo's ESP32marauder. Once you've connected the devboard,follow these instructions:

ATTENTION: do not modify the duration of the deauth, because if you set it for more then one second, the risk is that you will not catch EAPOL packets and then, you woun't be able to extract WPA/WPA2 handshakes to analyze, and extract the password.

• Once create, to run the script, open [ESP32] Marauder App, Scan all the APs, select the target one, go down in the menu to "Scripts", click on your new script and press "Run". The script is gonna make all the work.
  Then go to the "apps_data" folder, from the root of your Flipper Zero's FS, "marauder", and finally "pcaps". There you'll find the file you will need to run properly this tool.

• In order to correctly save the "pcaps" files on the SD card of your Flipper Zero, you must have flashed the correct version of the "Marauder" firmware (esp32_marauder_vX_X_X_xxxxxxxx_flipper_sd_serial.bin), on your "Devboard" (whether official or handmade); and that you have set the saving of the pcaps on the Flipper Zero external memory (you can set this when you first start the [ESP32] Marauder app, or later, from the app's menu).

This tool is not developed by the Flipper Zero staff.
