How To: Evil-Twin (Part 1) - Setting Up the Dhcp Server.

Hello again,

***UPDATE: Adding links to the other Two articles****

I recently started working on creating evil twin ap's, after reading OTW's article. I wanted to find a way to automate this process as much as I could, so I started looking for sample bash scripts and found this . Both of these together gave me the info I needed to write my MY VERY FIRST BASH SCRIPT.

This will be a three part post as there is some set up then the bash script. This is the first part on getting your system set up to run a evil twin ap, Setting up the dhcp server.

Step 1: Step 1: Getting Your System Ready!

• Install isc-dhcp-server: apt-get install isc-dhcp-server
• cd into the dhcp directory: cd /etc/dhcp

• make a master copy of the dhcpd.conf file: mv dhcpd.conf dhcpd.conf.org

Step 2: Step 2: Time to Create a New dhcp.conf File

• while still in the /etc/dhcp directory run your favorite text editor. I like nano: nano

• enter in this text:

ddns-update-style none;

# option definitions common to all supported networks...
#enable if you know your target has these set.
#option domain-name "example.org";
#option domain-name-servers ns1.example.org, ns2.example.org;

default-lease-time 600;
max-lease-time 7200;

#this section you can customize to fit your needs. Make sure you are
#using a private network settings

subnet 10.0.0.0 netmask 255.255.255.0 {
#these two options should be obvious on how to set
option subnet-mask 255.255.255.0;
option broadcast-address 10.0.0.255;

#this option below will be your fake ap's ip, do not make it
# obvious like 10.0.0.1
option routers 10.0.0.254;

#you will want to use a public dns server such as google's
option domain-name-servers 8.8.8.8;

#this is the range of ip's that will be assigned to your clients
range 10.0.0.1 10.0.0.140;
}

• save the file as dhcpd.conf

I will continue the next part of this on another post. The following post will include the bash script and an explanation of what it is. Tune in.

As always I hope this helps someone and if you see something that could be done better please point out.
