Posted this quick guide so people who aren't technical at all can follow and use CAIN (like I was!) to sniff their network and grab passwords. Lets begin!

To install:

• 1) Download and install Cain & Abel from http://www.oxid.it/cain.html
• 2) Install software and WinPcap packet capture driver
• 3) Reboot computer.

Instructions to use CAIN (APR):  Before you try this, you must make sure that WinPcap is properly bound toyour NIC. Select Configure and make sure you see your a dapter ( s) listed. See illustration

At main screen, select Configure, then click your your network adapter, then Apply and Ok.

 



 

 

• Click to enable both Sniffer and APR (Left of the + ).
• Click on +, then Range. Range for your network (based on adapter you chose) is displayed. Click OK to start scanning.
• After 100% you will see IP address, MAC, and OUI fingerprint of devices in range.
• Now click on APR icon to enable it.
• Click on + and select IP address to poison, then OK
• Now you should see it change from Idle to Poisoning.   
• IP connections should appear from target and spoofing computer(your computer)
• So, what we have now, is all the packets are going through your network are being picked up by CAIN and sniffed.. Whats useful about this tool is the passwords page, once someone logs on when your sniffing, their ID and PW are shown their as long as you are configured to pick up that login and pw. Yay!

Good luck, hope this guide showed you the basics of using CAIN if you never used it before.
