PCredz
PCredz is a tool developed by lgandx that can either live capture on an interface or parse a PCAP file to extract cleartext information such as logins via FTP, POP, HTTP, or SNMP Community Strings (and much more). Additionally, this tool will also extract credit card numbers which is perfect for PCI engagements.
