Communication using storage channels - Modify the storage location, for example, a hard drive, to communicate. Operation performed on timing channels that affects an observer's "real response time" reading.
What are the two main types of covert channel?
A covert channel is a timing channel or a storage channel that can be used for different purposes. The use of system resources will be modulated in a covert timing channel in order to relay information based on different timings.

re-routes communications into unintended routes or uses unintended programs. The Trojan can communicate with or "phone home" undetected through the covert channel, and hacker commands can be sent undetected to the client component.
What is a covert channel attack?
