How they attack
Entry
Exploiting outdated business servers
Like entering through a back door whose lock hasn't been changed in years (unpatched business software).
Inside
Jumping from the office network to the cloud
Like finding the storage-unit key (the cloud) in the office key box and taking over the unit as an admin with no second check (no MFA).
Goal
Wiping the backups to extort
Like taking the documents, shredding the spare copies, and then demanding payment to restore them.
