Introduction
In this post, you will learn what is arpspoof and how does it work and also you will learn how to use the tool.

What is arpspoof ❓
ARP stands for “Address resolution protocol” table on the router and the target system.
The ARP tables tell a system what physical MAC address an IP address is actually located at.
So we tell the Target machine that we are the internet router and tell the router that we are the target system.
We can modify ARP tables easily with the “arpspoof” program. But first, we need to turn on
IP forwarding by running the following command:
echo 1 > /proc/sys/net/ipv4/ip_forward
Commands in arpspoof
There are only few commands in arp-spoof they are;
- -i: interface
- -c: own|host|both
- -t: target
- -r: Poison both hosts
- host: Specify the host
Creating MIMT (Man in middle attack using arp-spoof)
Firstly we should do IP forwarding just enter the below command to forward IP’s. You should have root access to use this command.
echo 1 > /proc/sys/net/ipv4/ip_forward
Now we need to run the arpspoof command. To do so, we need to provide the network
interface (-i), the target system (-t) and the router address as below:
arpspoof -i eth0 -t 192.168.198.132 192.168.198.2
arpspoof -i <Network> -t <Victim> <Router>
-i: Interface
-t: Target
(You may or may not have to re-run the command reversing the IP addresses to set up the reverse connection. Reversing did not seem to work on a VMWare host, but I was able to capture all the traffic by just using the one-way command above)
Arpspoof should then start sending out the modified MAC addresses.
Now let’s see what we can capture from the target system.
Now, you can use tools such as driftnet and urlsnarf to listen to the target. I have already written a blog post on driftnet and urlsnarf [Click here] to read.
Conclusion
Arpspoof is a great tool for MIMT attacks and by just using arpspoof you can’t gather much information about the target. Still, you should depend on other tools to get quality information.
