pcapfex

pcapfex (Packet CAPture Forensic Evidence eXtractor) is a forensic tool that analyzes packet capture files to identify and extract embedded files. The tool processes pcap files and provides structured exports of all discovered files, regardless of whether standard or non-standard protocols were used during transmission. It operates through automated file detection and extraction processes that scan network traffic data for file signatures and content. pcapfex includes a plugin system that allows Python developers to extend functionality by adding support for additional file types, encoding methods, or complex network protocols. The modular architecture enables customization for specific forensic analysis requirements. The tool is designed for Linux environments and requires Python 2.7 with the dpkt package as dependencies. Optional integration with the regex package can improve performance during multithreaded file object searches. pcapfex outputs extracted files in an organized structure, facilitating forensic examination of network communications and data transfers captured in packet traces.
