API Reference: MITM Attack Simulation Agent
Overview
Simulates man-in-the-middle attacks using Scapy for ARP spoofing, detects cleartext protocol usage, and checks HSTS enforcement. For authorized penetration testing and lab environments only.
Dependencies
| Package | Version | Purpose |
|---|---|---|
| scapy | >=2.5 | ARP spoofing, packet sniffing, host discovery |
| requests | >=2.28 | HSTS and SSL stripping checks |
CLI Usage
# Host discovery and cleartext detection
python agent.py --network 192.168.1.0/24 --interface eth0 --duration 60
# Full MITM simulation
python agent.py --target 192.168.1.100 --gateway 192.168.1.1 --interface eth0
Key Functions
get_mac(ip_address)
Resolves MAC address for a given IP using ARP request via Scapy.
discover_hosts(network_cidr)
Discovers live hosts on a network segment using ARP broadcast scan.
arp_spoof(target_ip, spoof_ip, target_mac)
Sends a spoofed ARP reply to redirect traffic through the attacker machine.
arp_restore(target_ip, gateway_ip, target_mac, gateway_mac)
Restores original ARP tables by sending correct ARP replies after testing.
detect_cleartext_protocols(interface, duration)
Sniffs network traffic for cleartext protocols: HTTP (80), FTP (21), Telnet (23), SMTP (25), POP3 (110), IMAP (143).
check_hsts_enforcement(target_url)
Checks HTTP responses for Strict-Transport-Security headers.
run_mitm_simulation(target_ip, gateway_ip, interface, duration)
Executes a controlled ARP spoofing MITM simulation with automatic ARP restoration on completion.

Cleartext Protocols Detected
| Port | Protocol | Risk |
