Information theft through covert channel by exploiting HTTP post method

Abstract

Covert channel is a known vulnerability in most of the network protocols that makes it possible for peers to communicate non-legitimately using known channels. This papers aims at demonstrating information theft scenario by means of covert channel in which it is used as a carrier for transmitting information that is stolen by exploiting HTTP Post method. The paper describes and demonstrates a mechanism of information theft through covert channel exploitation. Some potential countermeasure techniques are suggested on the basis of observed covert channels which is part of our future work.
