NetCredz

NetCredz is a lightweight, dependency-free tool for extracting cleartext credentials and authentication data from network traffic. Inspired by PCredz, it provides enhanced functionality while maintaining simplicity and efficiency.

Features

  • Parse pcap files or listen on live network interfaces.
  • Filter traffic by specific protocols to reduce clutter.
  • Support for regex filtering to search for specific patterns or strings.
  • Output results to a log file for easy analysis.

Install

git clone https://github.com/joey-melo/netcredz.git

Usage

Run with a pcap file:

python3 netcredz -f capture.pcap

Run on a live network interface:

python3 netcredz -i eth0

Options

options:
  -h, --help            show this help message and exit
  -i INTERFACE, --interface INTERFACE
                        interface
  -f FILE, --file FILE  pcap file path
  -d, --debug           debug mode
  -v, --verbose         verbosity level
  -c FILTERS, --capture-methods FILTERS
                        capture methods
  -r REGEX, --regex REGEX
                        regex string
  -o OUTPUT, --output OUTPUT
                        output log file path (csv)

Supported Protocol

NetCredz supports the following protocols for filtering:

ntlm, ldap, http, smtp, snmp, telnet, ftp, kerberos, dhcpv6, llmnr

Future Enhancements

  • Implement remote logging to send captured data to a listening server.
  • Implement python2 version for backward compatibility.
