Re: XP compatablity
"not *THAT* insecure"
Well, anyone on the same network can access all of your files, and run arbitrary code on the machines hosting. I'm not sure how much more insecure it could get.
The flaws are the protocol level, so Samba was affected as well.
Basically running SMB1 is the equivalent of enabling remote desktop with no password, you should only do it on a completely air-gapped network, and you should think twice before you do even that.
