Lookup and Analyze Packet Capture (‘PCAP’) Files

Description

‘PacketTotal’ (https://packettotal.com/) is an engine for analyzing, categorizing, and sharing packet capture (‘PCAP’) files. The tool was built with the information security community in mind and has applications in malware analysis and network forensics. Methods are provided to query search for and analyze packet capture files.

What’s Inside The Tin

The following functions are implemented:

  • packettotal_api_key: Get or set PACKETTOTAL_API_KEY value
  • pt_deep_search/pt_get_search_results: Create a new deep search task. Search for a term or with a Lucene query.
  • pt_detail: Get a detailed report of PCAP traffic, carved files, signatures, and top-talkers.
  • pt_download: Download a PCAP analysis archive. The result is a zip archive containing the PCAP itself, CSVs representing various analysis results, and all carved files.
  • pt_info: Get high-level information about a specific PCAP file.
  • pt_random: Get high-level information about a random PCAP file.
  • pt_search: Search with term or with a valid Lucene query.
  • pt_similar: Get a similarity graph relative to the current PCAP file.
  • pt_usage: Retrive usage and subscription plan information.

Installation

install.packages("packettotal", repos = "https://cinc.rud.is/")
