Man in the Middle Attack [Network Spy]

Requirements:

1. Arpspoof

2. Driftnet

3. Urlsnarf

Step by step Kali Linux Man in the Middle Attack :

1. Open your terminal (CTRL + ALT + T kali shortcut) and configure our Kali Linux machine to allow packet forwarding, because act as man in the middle attacker, Kali Linux must act as router between "real router" and the victim. Read the tutorial here how to set up packet forwarding in linux.

2. You can change your terminal interface to make the view much more friendly and easy to monitor by splitting kali linux terminal window.

3. The next step is setting up arpspoof between victim and router.

arpspoof -i eth0 -t 192.168.8.90 192.168.8.8

4. And then setting up arpspoof from to capture all packet from router to victim.

arpspoof -i eth0 192.168.8.8 192.168.8.90

5. After step three and four, now all the packet sent or received by victim should be going through attacker machine.

6. Now we can try to use driftnet to monitor all victim image traffic. According to its website,

Driftnet is a program which listens to network traffic and picks out images from TCP streams it observes. Fun to run on a host which sees lots of web traffic.

7. To run driftnet, we just run this

driftnet -i eth0

When victim browse a website with image, driftnet will capture all image traffic as shown in the screenshot below.

To stop driftnet, just close the driftnet window or press CTRL + C in the terminal

8. For the next step we will try to capture the website information/data by using urlsnarf. To use urlsnarf, just run this code

urlsnarf -i eth0

and urlsnarf will start capturing all website address visited by victim machine.

9. When victim browse a website, attacker will know the address victim visited.

Here is the video in case you can't get the text explanations above.

Conclusion:

1. To change or spoof the attacker MAC address, you can view the tutorial about how to change kali linux MAC address.

2. Driftnet or Urlsnarf was hard to detect, but you can try to find the device in your network with promiscious mode which have possibliity to sniff the network traffic.

Hope you found it useful
