PCredz was built to extract credentials from large pcap files or from a live interface.


Stats on juicy pcap files:
– 30 mo pcap file : 15s
– 500mo pcap file: 1.5 minutes
– 2 Go pcap file: 7 minutes.


  • Extract from a pcap file or from a live interface:
    • Credit card numbers
    • POP
    • SMTP
    • IMAP
    • SNMP community string
    • FTP
    • HTTP Basic
    • NTLMv1/v2 (DCE-RPC,SMBv1/2,LDAP, MSSQL, HTTP, etc)
    • Kerberos (AS-REQ Pre-Auth etype 2#) hashes.
  • All hashes are displayed in a hashcat format (use -m 7500 for kerberos, -m 5500 for NTLMv1, -m 5600 for NTLMv2).
  • Log all credentials to a file (CredentialDump-Session.log).


  • Linux:

On a debian based OS: apt-get install python-libpcap

  • Os X and other distributions:

wget http://downloads.sourceforge.net/project/pylibpcap/pylibpcap/0.6.4/pylibpcap-0.6.4.tar.g
tar xvf pylibpcap-0.6.4.tar.gz
cd pylibpcap-0.6.4
python setup.py install


./Pcredz -f file-to-parse.pcap
./Pcredz -d /tmp/pcap-directory-to-parse/
./Pcredz -i eth0
-h, –help show this help message and exit
-f capture.pcap Pcap file to parse
-d /home/pnt/pcap/ Pcap directory to parse recursivly
-i eth0 interface for live capture
-v More verbose.
