NextGenSpoofer

An educational suite for ARP and DNS Spoofing

NextGenSpoofer is a research-oriented tool designed for educational purposes in cybersecurity labs. It provides both a Command Line Interface (CLI) and a Graphical User Interface (GUI) to demonstrate the mechanics of Man-in-the-Middle (MitM) attacks through ARP and DNS spoofing.
