__description__ = '''
Attempt to automatically convert pcaps to a crackable format.
If successful, the files containing the hashes will be saved
in the same folder as the handshakes.
The files are saved in their respective Hashcat format:
- EAPOL hashes are saved as *.2500
- PMKID hashes are saved as *.16800
All PCAP files without enough information to create a hash are
stored in a file that can be read by the webgpsmap plugin.
Why use it?:
- Automatically convert handshakes to crackable formats!
We dont all upload our hashes online ;)
- Repair PMKID handshakes that hcxpcaptool misses
- If running at time of handshake capture, on_handshake can
be used to improve the chance of the repair succeeding
- Be a completionist! Not enough packets captured to crack a network?
This generates an output file for the webgpsmap plugin, use the
location data to revisit networks you need more packets for!
Additional information:
- Currently requires hcxpcaptool compiled and installed
- Attempts to repair PMKID hashes when hcxpcaptool cant find the SSID
- hcxpcaptool sometimes has trouble extracting the SSID, so we
use the raw 16800 output and attempt to retrieve the SSID via tcpdump
- When access_point data is available (on_handshake), we leverage
the reported AP name and MAC to complete the hash
- The repair is very basic and could certainly be improved!
Todo:
Make it so users dont need hcxpcaptool (unless it gets added to the base image)
Phase 1: Extract/construct 2500/16800 hashes through tcpdump commands
Phase 2: Extract/construct 2500/16800 hashes entirely in python
Improve the code, a lot
