DNS Spoof script - hunt3r972 - 02-24-2014
This is a bash script to do DNS spoofing. You need to have ettercap installed to use it.
Code:
#!/bin/bash
echo ' ______ _ _______ _______ _______ _______ _______ _______'
echo '( __ \ ( ( /|( ____ \ ( ____ \( ____ )( ___ )( ___ )( ____ \'
echo '| ( \ )| \ ( || ( \/ | ( \/| ( )|| ( ) || ( ) || ( \/'
echo '| | ) || \ | || (_____ | (_____ | (____)|| | | || | | || ('
echo '| | | || (\ \) |(_____ ) (_____ )| _____)| | | || | | || __)'
echo '| | ) || | \ | ) | ) || ( | | | || | | || ('
echo '| (__/ )| ) \ |/\____) | /\____) || ) | (___) || (___) || )'
echo '(______/ |/ )_)\_______) \_______)|/ (_______)(_______)|/'
