This article is kind of silly. It has a short description of an attack that has been attributed to North Korea, but there are serious doubts about whether they actually had any part in it and then includes a very vague description of a possible cyber attack. The title is attention-grabbing, but their only support for it is North Korea getting angry about something that is decidedly /not/ negotiations (sanctions).

Seems like someone just took the opportunity to fear-monger, which really isn't what we need.
