Karmetasploit Configuration

There is a bit of setup required to get Karmetasploit up and going. The first step is to obtain the run control file for Karmetasploit:

root@kali:~# wget http://www.offensive-security.com/downloads/karma.rc
--2009-05-04 18:43:26--  http://metasploit.com/users/hdm/tools/karma.rc

Having obtained that requirement, we need to set up a bit of the infrastructure that will be required. When clients attach to the fake AP we run, they will be expecting to be assigned an IP address. As such, we need to put a DHCP server in place. Let's configure our 'dhcpd.conf' file.

root@kali:~# cat /etc/dhcp3/dhcpd.conf
option domain-name-servers 10.0.0.1;

default-lease-time 60;
max-lease-time 72;

ddns-update-style none;

authoritative;

log-facility local7;

subnet 10.0.0.0 netmask 255.255.255.0 {
  range 10.0.0.100 10.0.0.254;
  option routers 10.0.0.1;
  option domain-name-servers 10.0.0.1;
}

Then we need to install a couple of requirements.

root@kali:~# gem install activerecord sqlite3-ruby

Now we are ready to go. First off, we need to restart our wireless adapter in monitor mode. To do so, we first stop the interface, then use airmon-ng to restart it in monitor mode. Then, we utilize airbase-ng to start a new network.

root@kali:~# airmon-ng

wifi0        Atheros        madwifi-ng

root@kali:~# airmon-ng stop ath0

root@kali:~# airmon-ng start wifi0


Found 3 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!

Airbase-ng has created a new interface for us, at0. This is the interface we will now utilize. We will now assign ourselves an IP address and start up our DHCP server listening on our new interface.

root@kali:~# ifconfig at0 up 10.0.0.1 netmask 255.255.255.0
