Dexter is an automated computer scanning and hacking tool.

It functions using an OpenWRT Wireless Access Point to provide an internet connection. Dexter will automatically attempt to attack any user that connects to it. It does this by monitoring the DHCP and Squid logs to detect newcommers to the network. After detection a series of attacks are triggered the status of which is shown on screen. Any subsequent web traffic is also shown.

apt-get install nmap dhcp3 squid
