NATO can trigger Article 5 in case of Russian cyberattacks, NATO leader Jens Stoltenberg said in an interview to Axios. 

According to the Secretary General, the decision on a joint NATO response would not be taken automatically.

"Not automatically. It depends on the character of the cyberattack. We will never be specific on when we trigger Article 5,” he added.

According to NATO Article 5, “collective defense means that an attack against one Ally is considered as an attack against all Allies.”
