Covert Channels can be used for enabling hidden communication mechanisms that can facilitate secret message transfer. This paper presents a new covert channel based on the HTML source of a webpage. The new covert channel while featuring high bandwidth also demonstrates high imperceptibility as it doesn’t involve any modifications to the source or the visibility of the webpage and is independent of timing of page requests. The availability of page source for a webpage on the Internet makes this covert channel easy to implement and effective.
