On the high seas of the Internet there is a thin line between pirates and state actors. There could even be "privateer" (https://en.wikipedia.org/wiki/Privateer) attackers who work for a nation and for profit at the same time.

From the victim's perspective it matters less who is attacking you or why they are attacking you and much more what the results of the attack are, how you can mitigate and recover from the damage, and what needs to be done to prevent future attacks.

For the case of DarkSide and Colonial Pipeline, the attackers did not claim to have a political motive, but the resulting fuel shortages and panic buying might as well have been a form of terrorism.
