'BlackSheep' Sniffs Out Firesheep WiFi-Hacking

    A researcher today released a Firefox plug-in that serves as an early warning system of sorts for WiFi users whose Web sessions are either at risk or have been already hijacked by someone running the Firesheep sidejacking tool. The so-called BlackSheep tool is meant as a counter-punch to the new Firesheep plug-in for Firefox that makes it possible for anyone, technical or not, to easily hijack another user's HTML session cookies over a WiFi network. The Firesheep sidejacking tool, developed by Eric Butler, a Seattle-based Web application software developer and researcher, takes a new spin on an already known attack: it basically makes these types of attacks point-and-click.

    The tool shows a "Start Capturing" button, which when clicked, shows names and photos of Facebook users on their accounts on the WiFi network at the coffee shop or hotel. Firesheep has attracted hundreds of thousands of downloads since Butler unleashed it during Toorcon last month.
