Detection

Detectable by Common Defenses (Yes/No/Partial): No

Explanation: Defender will not know at first use what is valid or hostile traffic without more context. It is possible, however, for defenders to see if the PTR record for an address is hosted by a known DDNS provider. There is potential to assign some level of risk based on this.

Difficulty for the Adversary

Easy for the Adversary (Yes/No): Yes

Explanation: Flexible and re-configurable command and control servers, along with deniable ownership and reduced cost of ownership.
