That bulletin is for March.... this is a new variation which has been hitting over 40 countries now.
My brother and I were discussing it this afternoon fro his work place....it’s coming in on e-mail.....so people should watch what they are clicking open carefully. They should do that anyway.....
Due to NDAs with Microsoft, I can’t directly reference the bulletin we received from them, but they’re assuring customers that patching with MS17-010 will mitigate this vulnerability.
It’s also HIGHLY recommended you disable SMB1.0 since that’s the easiest mechanism for the malware to spread.
