How to Protect Facebook or Twitter from Firesheep Attack

If you have Facebook or Twitter account, then you should read this article to understand an easy way to steal Facebook or Twitter session and ways to protect it.

There is an easy way to use Firefox extension which is called Firesheep to sniff and steal unencrypted cookies of Facebook, Twitter or other major websites. This Firesheep extension works well on Firefox browser version 3.6.13 or 3.6.24, but might not compatible with latest version of Firefox web browser.

How it does the job? Well, after you have installed this extension in Firefox web browser, you just need to open the Firesheep sidebar and click Start Capturing. As many websites only encrypt the network traffic during login process, but then make use of unencrypted connection for user data communication, and so the unencrypted cookies will be easily captured by Firesheep and the session will be hijacked eventually. Once the session is hijacked, Firesheep shows captured credentials (Facebook, Twitter, etc) on a sidebar displayed in the browser, and allows you to instantly take over the hijacked session by double-clicking on the victim’s name.
