Though, intercepter isn't a part of Kali, no one can prevent us from installing it manually.
1. wget http://intercepter.nerf.ru/Intercepter-NG.CE.05.zip
2. unzip Intercepter-NG.CE.05.zip
3. chmod +x intercepter_linux
4. ./intercepter_linux
UPDATE:
Found a better instruction from someone's scripts for kali:
1. wget http://intercepter.nerf.ru/Intercepter-NG.CE.05.zip
2. unzip Intercepter-NG.CE.05.zip
3. chmod +x intercepter_linux
4. ./intercepter_linux
UPDATE:
Found a better instruction from someone's scripts for kali:
