p4lantir 1.0.0

MiTM over TCP to intercept and manipulate flow

p4lantir

---

p4lantir is a simple tool to perform Man-in-the-Middle over TCP using ARP spoofing, allowing to intercept, drop, forward and see TCP flows.

This project is intended to be relatively simple, making simple future contributions for new features/bug fix.

[!CAUTION] This ethical hacking project is intended for educational purposes and awareness training sessions only. I decline all responsability about the usage of this project.

Installation

• Install the system dependencies (arpspoof, iptables)
• Create python virtual environnement
• Install the package

Setup instructions :

• Debian-based (Debian, Kali, Ubuntu,...)
• Archlinux

Debian-based systems

sudo apt install dsniff iptables

python3 -m venv venv
source venv/bin/activate

pip install p4lantir

Archlinux

pacman -S dsniff iptables

python3 -m venv venv
source venv/bin/activate

pip install p4lantir

Usage

[!WARNING] You need to run the script as root due to arpspoof and iptables. You should open a shell as root, activate the venv and then use p4lantir.

usage: p4lantir [-h] --host-1 HOST_1 --host-2 HOST_2 [--gateway GATEWAY] -i INTERFACE -l LPORT [--pport PPORT] [--debug]

Man-in-the-Middle over TCP terminal app.

options:
  -h, --help            show this help message and exit
  --host-1 HOST_1       First host to spoof, must be the host instanciating the connection
  --host-2 HOST_2       Second host to spoof
  --gateway GATEWAY     Gateway IP
  -i, --interface INTERFACE
                        Interface to perform arp spoofing
  -l, --lport LPORT     Port to listen for MITM attack
  --pport PPORT         Internal port used for proxy.
  --debug               Enable debug mode.

Examples

Client/server in the same localhost

Let say that a client at IP C connect to a remote server at IP R, both in the same LAN. You need to know the name of the interface that connects you this LAN (let call this iface. Then your command should look like :

p4lantir --host-1 [replace with C] \
         --host-2 [replace with R] \
         -i [replace with iface] \
         -lport [server's listening port]

About the listening port, if you intend to intercept SMTP you may choose 25, 80 for HTTP, and so on ...

Client/server on a different LAN

If the client is in the same LAN as you and the server is not in your LAN, then you have to add another parameter : the gateway IP. p4lantir will then spoof the gateway IP and open a connection to the server.

p4lantir --host-1 [replace with C] \
         --host-2 [replace with R] \
         --gateway [replace with gw's IP]
         -i [replace with iface] \
         -lport [server's listening port]
