Developer Eric Butler has exposed the soft underbelly of the web with his new Firefox extension, Firesheep, which will let you essentially eavesdrop on any open Wi-Fi network and capture users’ cookies.
As Butler explains in his post, “As soon as anyone on the network visits an insecure website known to Firesheep, their name and photo will be displayed” in the window. All you have to do is double click on their name and open sesame, you will be able to log into that user’s site with their credentials.
One word: wow.
It’s not hard to comprehend the far-reaching ramifications of this tool. Anytime you’re using an open Wi-Fi connection, anyone can swiftly access some of your most private, personal information and correspondence (i.e. direct messages, Facebook mail/chat)— at the click of a button. And you will have no idea.
