pcredz

Packet capture (PCAPNG) files store network traffic data, often used for network analysis and security investigations. Extracting credentials from these files can help security professionals identify potential vulnerabilities or detect unauthorized access. One powerful tool for this task is PCredz, an automated credential extraction tool designed to parse PCAP files and retrieve sensitive information such as usernames and passwords.

Using PCredz to Extract Credentials

PCredz simplifies the process of extracting credentials from PCAP files, whether from a saved capture, a folder containing multiple captures, or even live network traffic. Below are some practical usage examples:

Extract Credentials from a PCAP File

To extract credentials from a single PCAP file, use the following command:

python3 ./Pcredz -f file-to-parse.pcap

This will scan the specified file and display any credentials found.

Extract Credentials from Multiple PCAP Files

If you have a directory containing multiple PCAP files, you can automate the process by scanning all of them at once:

python3 ./Pcredz -d /tmp/pcap-directory-to-parse/

This is useful for forensic analysis involving large amounts of captured network traffic.

Extract Credentials from Live Network Traffic

PCredz can also capture and extract credentials in real-time from a live network interface. Since this requires monitoring network packets, root privileges are needed:

python3 ./Pcredz -i eth0 -v

Replace eth0 with the name of your active network interface.
