[Samba] Does WannaCry Ransmonware affect Samba?




Hello,

Up till today I have only heard that it affects Windows clients and Servers. However I received this today that sparked my question

https://ics-cert.us-cert.gov/sites/default/files/FactSheets/ICS-CERT_FactSheet_WannaCry_Ransomware.pdf

This suggests blocking port 445 for Samba specifically. First wouldn't blocking port 445 break all file and printer sharing functionality? Second isn't this port needed even by Windows for SMB? I'm confused. Thanks.
