Nation states
National governments - countries. (e.g., France) (e.g., India) (e.g., Ukraine)
Complexity: When countries decide to attack other countries in the information arena, they often use stealth to try to provide for plausible deniability, however this is not always the case, and they often fail to achieve true anonymity. Responses may lead to escalation - and in some cases - escalation can lead to full-scale war.
