Firesheep HTTP Session Hijacking Tools

What is Session Hijacking

Every time you connected to the web application (usually a dynamic web application) you will have a unique ID called "session", this session will identifies you as a valid user and will always valid until you kill the session (log out process) or the session has expired. Some bad people trying to identifies or guessing the session ID value to gain privileges as a valid user in a web application.

Firesheep HTTP Session Hijacking

Firesheep is a firefox extension to do the session hijacking. I was very surprised that this tools can hijack Facebook, Twitter, WordPress, Amazon, etc from the valid user. The most important thing that this tools is very easy to configure and to launch an attack. Just a few step : 1. Download firesheep 2. Sit on a unencrypted wireless network 3. Turn on your wireless card(support promiscious mode, such as : atheros, orinocco, etc) and join the network 4. Start capturing with firesheep 5. Just waiting until some user authenticate at the facebook, twitter, etc.

Step by Step Firesheep Configuration

1. The picture below is the interface of firesheep and you can click the red circle for preferences 

2. In this picture you should choose which interface you want to capture the data. for example when you're in a wireless network, you should activate the wireless adapter. 

3. This picture below tells you which website session can hijacked handle by this addons,

4. Usually when capturing data, will use TCP port 80, because if it's 443 I think will be encrypted, but I still didn't try for another port  .

5. When you finish, click the "Start Capturing" and wait until someone authenticate some website on the website list.

That's it. I hope you can use this tutorials in a good way  if any question, you can contact me or drop some comment.
