Ettercap Usage Example
Start Ettercap with GUI (-G):
sudo ettercap -G
Select Sniff -> Unified -> select Iface:
Now selext Hosts -> Scan for hosts -> Hosts list:
As Target 1 select Router (Add to Target 1), As Target 2 select a device for attack (Add to Target 2).
Mitm -> ARP poisoning… Select Sniff remote connections.
Sniff -> Start sniffing.
Start urlsnarf:
urlsnarf -i eth0
or driftnet:
driftnet -i eth0
