Beholder is a Python script for handling and parsing GNMAP files, making it more efficient to feed data to other tools.

• Parses GNMAP files and extracts relevant information
• Generates separate files for live hosts, individual hosts, and specific ports
• Creates a special file for web ports (80, 8080, 443, and ports > 1025)
• Generates a file for ephemeral ports (ports > 1025)
• Optional JSON output for easy integration with other tools

python beholder.py -i <input_GNMAP_file> -o <output_directory> [-j]

• -i, --ifile: Specify the input GNMAP file (required)
• -o, --ofile: Specify the output directory (required)
• -j, --json: Generate JSON output (optional)

Beholder generates the following files in the specified output directory:

• livehosts.txt: List of all live hosts
• <port>.txt: Files for each discovered port, containing "IP:port" entries
• web.txt: List of potential web services (ports 80, 8080, 443, and > 1025)
• ephemeral.txt: List of ephemeral ports (> 1025)
• hosts/<IP>.txt: Individual files for each host, listing open ports
• output.json: JSON output (if -j option is used)

python beholder.py -i scan_results.gnmap -o parsed_results -j

This command will parse the scan_results.gnmap file, save the results in the parsed_results directory, and generate a JSON output.
