LONDON/WASHINGTON, Feb 28 (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.
"Allies also recognise that the impact of significant malicious cumulative cyber activities might, in certain circumstances, be considered as an armed attack," the official told Reuters.
