Very. Honestly, they're often not that stealthy (especially N. Korea and Iran) because they have the mantle of an evil regime behind which they can hide. China and Russia barely moreso. Companies with whom I work have been ransomed by these actors, and the FBI has almost always said they know who did it and can do nothing. Policy set higher than them.
