YAASP stands for Yet Another Arp Spoofing Program, this software can be used to perform flexible Arp Spoofing attacks.

In order to install yaasp, few dependencies are required, once we have access to a cpan (or cpanm) we do:

$ cd path/to/yaasp

Now we first install cpanminus, I report the command to do it on Debian based GNU/Linux distros:

$ sudo apt install cpanminus

$ cpanm --installdeps . 

Let's see some usage examples:

$ perl yaasp.pl --tell-ip 192.168.1.105 --i-am 192.168.1.1 --interface wlan0 --delay 1

This will perform an unidirectional arp-spoofing with a delay between arp packets of 1 second.

$>perl yaasp.pl --tell-ip 192.168.1.105 --i-am 192.168.1.1 --interface wlan0 --bidirectional

This will perform a bidirectional arp-spoofing with a delay between arp packets, if the --delay is not specified, then packets are sent without any delay, notice that this will generate a lot of traffic on the network.

$ perl yaasp.pl --help

This will show a help message, where possible options are shown.
