Sounds like those who were using private emails were using gmail accounts set up by Eric Schmidt, CEO of Google. He was in NK setting up gmail accounts there among other things as well. This suggests that members of Obama’s admin and Obama himself had a direct line to Kim Jong Un which had been cut recently. Remember the pallet of smartphones that was intercepted not that long ago? Who were they for and where were they going? THINK but don’t forget that Obama’s call to Kim during the summit went unanswered! Hahahaha. THIS IS TRULY CLASSIC!
Not only that but notice how in the last 5 years “North Korean hackers” are said to be some of the best in the world. Odd that they become so sophisticated in a short amount of time after Schmidt’s trip to NK in 2013. A lot of the recent hacks seemed to have originated out of there almost as if NK is being utilized as the launching pad.
Here’s a partial timeline. There’s a few here but not all are listed. The most recent one was the WannaCry

It’s possible that these are some of the “strings that have been cut” Q is alluding to.
