Informational war is not a espionage, nor sabotage. It similar to sabotage, but, unlike sabotage, it's done from withing territory of attacker. If someone will destroy a factory behind enemy line, then it's sabotage. If someone will launch a rocket from their country to factory in another country, then it's not.
If it done by state military agency, then it's act of war.
If it done by civilians without support of and not directed by state, then it's terrorism.
If it done by civilians, with support of or directed by state, then it's state sponsored terrorism, a war crime.
There is no excuse for not wearing of uniform for warriors at their own country.
It's my opinion. If(when) I will catch Russian informational warriors, masqueraded as civilian journalists, I will treat them as spies, because they are not wearing uniform when doing war, even if they are doing their attack from their own country.
