Time for action – Man-in-the-Middle attack

Follow these instructions to get started:

1. To create the MITM attack setup, we will first create a soft access point called mitm on the hacker laptop using airbase-ng. We run the following command:

   airbase-ng --essid mitm -c 11 wlan0mon
   

   The output of the command is as follows:

   

2. It is important to note that airbase-ng, when run, creates an interface at0 (a tap interface). Think of this as the wired-side interface of our software-based access point mitm:

   

3. Let's now create a bridge on the hacker's laptop, consisting of the wired (eth0) and wireless interface (at0). The succession of commands used for this is as follows:

   • brctl addbr mitm-bridge

   • brctl addif mitm-bridge eth0

   • brctl addif mitm-bridge at0

   • ifconfig eth0 0.0.0.0 up

   • ifconfig at0 0.0.0.0 up

   

4. We can assign an IP address to this bridge and check the connectivity with the gateway. Please note that we can do this using DHCP as well. We can assign an IP address to the bridge interface with the following...
