Chapter 8: Network Infrastructure
ARP poisoning can be hazardous to your network’s hardware and health,
causing downtime and more. So be careful!
Perform the following steps to use Cain & Abel for ARP poisoning:
1. Load Cain & Abel and then click the Sniffer tab to enter the network
analyzer mode.
The Hosts page opens by default.
2. Click the Start/Stop APR icon (the yellow and black circle).
The ARP poison routing (how Cain & Abel refers to ARP poisoning) process
starts and enables the built-in sniffer.
3. If prompted, select the network adapter in the window that appears
and then click OK.
4. Click the blue + icon to add hosts to perform ARP poisoning on.
5. In the MAC Address Scanner window that appears, ensure the All
Hosts in My Subnet option is selected and then click OK.
6. Click the APR tab (the one with the yellow-and-black circle icon) to
load the APR page.
7. Click the white space under the uppermost Status column heading
(just under the Sniffer tab).
This re-enables the blue + icon.
8. Click the blue + icon and the New ARP Poison Routing window shows
the hosts discovered in Step 3.
9. Select your default route (in my case, 10.11.12.1).
The right-hand column fills with all the remaining hosts, as shown in
Figure 8-12.
