    Apply MS17-010. Disable SMBv1 entirely — there is no reason to run it in 2020+. Block 445/tcp at the perimeter. This is the WannaCry/NotPetya vector.

    Wormable pre-auth RCE in SMBv1. Still lights up honeypots years later because of unmanaged/OT devices. If SMBv1 is on, assume it's being probed.
