It's shameful that the government has to conduct this kind of awareness campaign with one hand tied behind its back. Who are the think tanks? State it publicly.
The problem is the attack and reading between the lines of the report the problem is probably a mix of blackmail and trying to gain access to whatever the think-tank knows or is debating (maybe to prepare in advance should their ideas become mainstream) since these are the sorts of people who probably won't have trouble trying to prove who they are after the initial compromise.

Plot-twist: They don't want awareness because western cyber capabilities are far and beyond the best the in the world. We hack ourselves and each other constantly. Most are aware of China/NK/Russia/Iran actors doing X action. You'll have a rough time finding anyone in the five eyes with common knowledge of their offensive capabilites. Perhaps Stuxnet but by all accounts that was all due gungho Israeli's going full-tilt rather than US allies.
