A Python tool that extracts HTTP streams from PCAP files and scans them with YARA rules for security analysis.
YaraPCAP is a Python-based security tool that processes PCAP (packet capture) files to extract HTTP streams and scan them with YARA rules. It helps security analysts identify malicious patterns in network traffic by applying signature-based detection to captured data. The tool automatically handles compressed content and generates reports of matches for further investigation.
Security researchers, network analysts, and incident responders who need to analyze captured network traffic for malicious activity using YARA rules.
Developers choose YaraPCAP for its focused approach to applying YARA pattern matching directly to network traffic, its automatic handling of compressed HTTP streams, and its simple command-line interface that integrates with existing forensic workflows.

Specifically extracts HTTP streams from PCAP files, enabling targeted analysis for web-based threats without manual packet sifting.
Seamlessly decompresses gzip-compressed HTTP streams, ensuring scanned content is accessible without additional tools or steps.
Directly applies custom YARA rule sets to extracted files, leveraging signature-based detection for efficient malicious pattern identification in network data.
Optionally saves matching files to a specified directory with the '-s' flag, facilitating forensic evidence collection for further investigation.
Requires TCPFlow 1.3 to be installed and configured separately, adding setup complexity, especially on Windows where manual script editing is necessary (line 29).
Focuses only on HTTP traffic, making it ineffective for analyzing other common protocols like HTTPS, SMTP, or FTP in network captures.
Generates only text reports with minimal detail, and advanced features like XML output are incomplete as noted in the ToDo section of the README.
