Quickly Triaging HTTP Traffic From GreyNoise’s New Hosted Sensors

This post outlines a workflow to triage HTTP requests from PCAP files by integrating Python’s Scapy with R via the reticulate package, extracting key fields (IP, method, path, headers, and base64-encoded POST bodies) and returning them to R for rapid analysis and tagging. It includes example functions (packet_handler and read_pcap), demonstrates binding results into a data.table in R, and positions the approach as a lightweight alternative to heavier tooling for targeted packet inspection.
