On-prem ransomware is a crowded business: lots of competition, and when defenders do things right, backups are hard to kill. That pushes attackers to look for easier wins — and Microsoft 365 is an appealing target. Many organizations still rely mainly on “on-prem era” security technologies like AV/EDR, NGFW, sandboxes, or network-based IPS. Those tools can be great for endpoints and networks, but they don’t cover cloud services — which creates a blind spot. And it’s not a small one: Microsoft 365 isn’t a marginal service anymore, it’s a core part of the infrastructure for a majority of organizations.
