What's Your Take on the Cyber Component of This Conflict?

CNN's John Defterios asked the former CIA director for his thoughts on cyber activity. He said he was surprised at the minimal level of cyber activity we've seen from the Russian side. The Russians have always used patriotic hackers, some of whom have left the country to go make money doing cyber work and information work outside of Russian places where they can earn a living,. But no, there has not been an internet of things attack on the air conditioning systems at the Pentagon, Saturday night at midnight in August. I think this is very alarming to both sides. There are things that could be done to the backbone of the internet.
