I'm going to be careful because we're not convening in camera. There are security levels that are required for me to discuss in open context that question.
I will say the following. If you look at the December 27 Department of Homeland Security-FBI JAR report, which provided specific details to Russia's involvement with the electoral process south of the border, which was spoken to earlier, that is direct evidence of the capability, sophistication, and pervasiveness of the Russian cyber-threat.
From a hybrid solution in these other jurisdictions, I can go back and we can revisit this, but we have a pretty clear indication of attribution in Russia in at least two or three of those arenas, one specifically with Sandworm, with the Ukraine outages that we saw in 2014 and 2016.
Again, there is some concern. In Estonia, I believe, they did not want to come and say outright that there was an attribution there. We're not sharing that information, which is unfortunate. It's hard to make that determination.
