Abstract
In this paper we propose the use of URLs as a covert channel to relay information between two or more parties. We render our technique practical, in terms of bandwidth, by employing URL-shortening services to form URL chains of hidden information. We discuss the security aspects of this technique and present proof-of-concept implementation details along with measurements that prove the feasibility of our approach.
