GQUIC Protocol Analyzer is a Zeek-based network protocol analyzer designed to parse and examine GQUIC traffic for logging and detection purposes. The tool analyzes the initial communication exchange between clients and servers using the GQUIC protocol, extracting detailed information from client hello packets and server rejection packets. The analyzer supports GQUIC protocol versions Q039 through Q046, providing comprehensive coverage for modern GQUIC implementations. It integrates directly with the Zeek network security monitoring platform, requiring installation through source compilation with proper Zeek distribution paths. A key feature of this analyzer is its fingerprinting capability using the "CYU" method. This fingerprinting technique identifies GQUIC versions and extracts tags present in client hello packets, creating unique fingerprints by concatenating version information with hyphen-delimited tag sequences. This approach enables the detection of anomalous and potentially malicious GQUIC traffic patterns. The tool generates structured logs containing connection metadata, protocol version information, and extracted packet details. Installation requires standard build tools and involves configuring the analyzer against an existing Zeek distribution, followed by compilation and installation steps.
