Consider wikipedia's take on the subject of self published sources:
" Self-published expert sources may be considered reliable when produced by an established subject-matter expert, whose work *in the relevant field* has previously been published by reliable, independent publications."

Of thr people mentioned here, we have one of the world's foremost security experts, and a fox news host making a decision about cyber security. There is no evidence that the fox news host's experience is more relevant to this domain.
That was just a low shot.
I get that cybersecurity is his domain. But this is about national defense and international politics no? He is taking a jab at a different (bigger) topic based on his domain.
In my experience when people do this, it doesn't play out, people get overconfident and explore the limits of their competence. But he might be on to something, who knows, time will tell. It's just not statistically likely for me
And in Krebs defense, the topics are interrelated, it's not like he just gave his opinion on a completely unrelated manner like covid (remember when everyone had an opinion on that?)
