  • HTTP Inspection: Inspect HTTP requests and responses for detailed analysis.
  • Raw Payload Viewing: View raw payload data for deeper investigation.
  • Device Information: Gather information about network devices, including IP addresses and MAC addresses.

Installation

git clone https://github.com/HalilDeniz/PacketSpy.git

Requirements

PacketSpy requires the following dependencies to be installed:

pip install -r requirements.txt

Getting Started

To get started with PacketSpy, use the following command-line options:

root@denizhalil:/PacketSpy# python3 packetspy.py --help                          
usage: packetspy.py [-h] [-t TARGET_IP] [-g GATEWAY_IP] [-i INTERFACE] [-tf TARGET_FIND] [--ip-forward] [-m METHOD]

options:
  -h, --help            show this help message and exit
  -t TARGET_IP, --target TARGET_IP
                        Target IP address
  -g GATEWAY_IP, --gateway GATEWAY_IP
                        Gateway IP address
  -i INTERFACE, --interface INTERFACE
                        Interface name
  -tf TARGET_FIND, --targetfind TARGET_FIND
                        Target IP range to find
  --ip-forward, -if     Enable packet forwarding
  -m METHOD, --method METHOD
                        Limit sniffing to a specific HTTP method
