Now anyone can have L33t HaX0r skilz.
Firesheep, though, has an easy-to-use interface and, perhaps most importantly, a cute name. Surely this can’t be a “cracking tool”? It wasn’t released by someone going by a name like ‘dEvILSp0RN42’. It doesn’t feature white text on a black background. It has well-thought-out and literate documentation. To use it, you simply install it into Firefox and click a few buttons. One minor additional step, installing WinPcap, is required for Windows users.
You can watch a demo on YouTube (I was unable to embed the video).
