Your Backup Server Is a Domain-Admin Factory: The Kill Chain Ransomware Operators Have Automated
The backup server is the highest-privilege machine in most environments and the least-hardened. Ransomware operators have known this for years and built repeatable kill chains around it. This is how they work and what it takes to stop them.
