Sidejacking. This is likely old news for many of you but I just learned of it today through my internet service provider monthly e-newsletter. Why on earth would Firefox provide a plugin to make it easier?

From the newsletter:

WARNING! - Sidejacking at Wi-Fi hotspots

Sidejacking is the term used to describe the malicious act of hijacking an engaged Web session of another user on the same Wi-Fi network. Although such attacks are not new, they used to require sophisticated technical expertise. But a popular new Firefox plugin named Firesheep has made sidejacking easier for amateurs.

For example, an intruder sitting nearby you at an airport could use Firesheep to silently take over your Facebook session, gain access to your sensitive data, and send viral messages and wall posts to all of your friends. Even your wireless home network could be subject to sidejacking if not securely configured, since drive-by hackers might be in the neighborhood.

As a precaution, try to avoid highly sensitive online activities while at a hotspot since security may be unreliable; your data (such as passwords) could be allowed to travel unencrypted within range of the wireless router. It is generally safe, however, to use public Wi-Fi for accessing sites with an address that starts with https; those sites provide end-to-end encryption. Password-protected hotspots are usually safe, too.

On your wireless home network, be aware that the old protocol known as Wired Equivalent Privacy (WEP) can be easily broken with readily available software. Only the stronger Wi-Fi Protected Access (WPA) will prevent local snoops from being able to decipher the dialog between your computer and the wireless router.

In the articles it says "Even your wireless home network could be subject to sidejacking if not securely configured". How does one go about doing that?
