About

Sniff-NG is a Python tool for network security testing.
It provides fast local network device scanning, ARP spoofing (MITM), and a fully interactive TUI menu.
Supports Linux and macOS with automatic dependency installation paths.

---

Features

• TUI interface: no command line needed
• Network scanner: find all devices in the local network
• Auto gateway detection: detects default router IP for faster setup
• ARP spoofing / MITM: easy attack launch via menu
• Restore ARP tables: clean up after attacks
• One-click dependency install: Linux package managers + Homebrew on macOS
• Python 3.8+ compatible

---

Requirements

• Linux (Debian, Ubuntu, Arch, Fedora, CentOS, etc.) or macOS
• Python 3.8+
• Tools: arp-scan (dsniff is Linux-focused)

---

Installation

git clone https://github.com/Secret297-CODER-SOURCE/Sniff-NG.git
cd Sniff-NG
sudo python3 console_ui.py

Run with sudo!
Most features require root privileges for network access.

If dependencies are missing, select "Install dependencies" in the TUI menu.

macOS notes

• Install Homebrew first: https://brew.sh
• Run Sniff-NG with elevated privileges (sudo) for raw packet operations.
• On macOS, scanner can use arp-scan (if installed) or Scapy ARP fallback.
• Linux iptables redirect helpers are not used on macOS (pf must be configured manually if you need redirect/NAT rules).

---

Usage

All features are available via the TUI menu:

• Network Scan: shows all connected devices
• ARP Spoofing: attack any target/gateway on your LAN
• Restore ARP: cleans up ARP tables
• Install dependencies: one-click setup

Controls:

• Up/Down: navigate
• Enter: select
• Hints at the bottom
