Abstract
JavaScript on webpages linked to by URLs in messages is identified and the JavaScript is extracted. The JavaScript is then subjected to a JavaScript execution and analysis process whereby the JavaScript is executed in the context of a simulated web browser. The behavior of the JavaScript is then analyzed to identify one or more of: any URLs to be redirected to; any further executable JavaScript; and any content dynamically written to the webpage. The results are then either recursed into or are recorded and used to aid in the identification of spam messages.
