Firesheep by Eric Butler has just been released to the world. This Firefox plugin does a few things that have already been fairly easy to do for a while, but rolled up in one easy to use package:
- Sniffs data on unencrypted Wireless Networks
- Looks for unencrypted login cookies sent to known popular insecure sites
- Allows you to login to that account with ‘One Click’
So what sites are impacted by default? Amazon.com, Basecamp, bit.ly, Cisco, CNET, Dropbox, Enom, Evernote, Facebook, Flickr, Github, Google, HackerNews, Harvest, Windows Live, NY Times, Pivotal Tracker, Slicehost, tumblr, Twitter, WordPress, Yahoo, and Yelp are among the few. A plugin system allows anyone to add their own sites (and cookie styles) to the plugin.
Yikes! It goes without saying that this is a major security problem for anyone who uses unencrypted wireless networks. Includes on this list are many universities and companies such as Starbucks.
