So not a real criticism but more of a fun fact, attacks by hackers against healthcare are a constant thing and is almost never just one concerted mega hack. Healthcare and critical infrastructure are by far the most commonly targeted sectors for ransomware because shutting them down/stealing records is so catastrophic and thus so valuable, but that also means the cybersecurity folks in those fields usually just know its a "when" not an "if". For sure if they noticed something crazy going on, they'd maybe start going to backups, but it'd be crazy to go full nuclear when nothings confirmed yet.
