There are no such things as coincidences.
These "coincidences" are happening, what ever they may be, are occurring with peculiar regularity now.
Not a coincidence. Basically, ten years ago, cybersecurity was, "buy a multimillion dollar tool, let it run." Strong wall, no back court game.
With more people getting into cyber, and red teamers, both normal groups and nationstates, improving their professionalism and development skills, there's been an explosion of novel and mutating malware. It used to be that the big stuff was rare, because it took a lot of work to make the malware for it. Now, teams can focus on just the big stuff that hurts
Add to that that critical infrastructure, you don't see "patch Tuesday," you see "patch September," it's the perfect storm of rapidly escalating offensive skills, defenders playing catchup, and ics stuff being, by design, outdated.
This is gonna keep happening, until defense catches up to offense. No need to look for a conspiracy theory, the truth is a lot more frightening.
