MAC crack

Installation

• Install nodejs from http://nodejs.org/download/
• download the Ripo as Zip or what ever (and extract it)

Usage

use [sudo] node main.js [interface] to start the script. This operation will need super user rights. If the interface is not specified an awful function will try to guess a working interface, so at the moment it's better to specifie the interface.

How it is working

1. sudo fing

The script starts with scanning the network with fing. Fing's output will be saved in nodes.csv as a comma seperated file. The file contains all MAC-Addresses in the network.

2. ifconfig hw ether [mac]

Now your MAC-Address gets changed to the one's in the nodes.csv file.

3. curl google.com

Now the script tests Internet-connectivity. curl gets google.com. curl will return an empty string, if it get's redirected etc, so I can be sure, that access is properly working.

Why it is working

Networks handle authentification over your MAC-Address (because it's the only thing that can('t) change). If other devices on the network have rights for internet access, you can use their MAC-Addresses (and Identity) to get Access too.
