Paranoid at the Airport about yet another security issue

By listening to and storing radio signals from the airwaves with any laptop, an attacker can harvest cookies from multiple users and go in to their Web 2.0 application.  Even though the password wasn’t actually cracked or stolen, possession of the cookies acts as a temporary key to gain access to Web 2.0 applications such as Gmail, Hotmail, and Yahoo.  The attacker can even find out what books you ordered on Amazon, where you live from Google maps, acquire digital certificates with your email account in the subject line, and much more.
