The big news of the week, emanating from Toorcon 12, is the release of Firesheep. This tool makes SideJacking – that is, “hijacking an engaged Web session with a remote service by intercepting and using the credentials that identified the user/victim to that specific server” – painfully simple for anybody to use. How easy? Well, let’s see… you download and install Firefox… and then you download and install the Firesheep extension to Firefox… and then you restart Firefox and run the tool to start hijacking sessions… that’s it!

I can easily throw myself onto that band wagon, but there is one feature that has been causing a little commotion, and I again can easily agree with the commotion. Firefox 3 (FF3) limits usable, encrypted (SSL) web sites to those that have an approved digital certificate from an authorized vendor of Mozilla’s choosing, making it so you have to pay to be recognized. What’s the big deal? When you visit an encrypted site in FF3, and that site uses a self-signed or simply unapproved certificate, FF3 doesn’t immediately show the page.
