LONDON/WASHINGTON (Reuters) -A cyberattack on a NATO member state could trigger Article 5, its collective defence clause, a NATO official said on Monday, amid concerns that chaos in cyberspace around Russia's invasion of Ukraine could spill over into other territories.
The military alliance has for years made clear that a serious cyberattack could trigger the clause, but such a scenario has so far been largely hypothetical.
