Developer Eric Butler has has created a new Firefox extension called Firesheep that allows anyone to download and start eavesdropping on any open Wi-Fi network and capture users’ cookies. Then allowing you to login to their Facebook and Twitter accounts with ease.
Butler explains in his website 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.
Double-click on someone, and you’re instantly logged in as them.
Firesheep is free, open source, and is available now for Mac OS X and Windows. Linux support is on the way.
Butler explains :
Websites have a responsibility to protect the people who depend on their services. They’ve been ignoring this responsibility for too long, and it’s time for everyone to demand a more secure web. My hope is that Firesheep will help the users win.
