A UK software developer has released a tool that can hijack Twitter sessions. The tool, dubbed Idiocy, monitors unencrypted wifi traffic, extracts cookie headers for domains (like Twitter.com) that its interested in. It then uses cookies to send requests to send HTTP requests to the user s Twitter account that tweet a message and link to an explanatory Web page set up on developer Jonty Wareing’s blog. Unlike Firesheep, the tool is built to run on Linux and OSX, but does not have out of the box support for Windows.
