I just wrote a new paper about a way to realize covert channels I call
"protocol hopping covert channels". I also wrote a simple PoC code.

Protocol Hopping Covert Channels (PHCC) are a way to realize covert
channels that switch between different protocols while a covert channel
is established. PHCCs even can use a randomized protocol order and a
mixed packet order to transfer packets what makes them hard to

The paper and the PoC code is available here:
