Wanna cry virus

[Daniel Moreira]

Hello,

About the wanna cry virus that triggered many problems around the world.
I have read that the vulnerability is the smb v1 protocol. Windows XP has used it, so XP guests may be in trouble sharing folders with its hosts. Is VirtualBox using smb to share folders? Is shared folders between guests and hosts immune to it?

Regards,
Daniel

XP guests may be in trouble sharing folders with its hosts

XP guests (or any other guest) does not share folders with the host; the host shares a folder with the guest. That's if you're talking about the VirtualBox shared folders. If you're talking about true network shared folders (SMB shares), that's another story.

Is VirtualBox using smb to share folders?

No. You can have no network card in your guest whatsoever and VirtualBox shared folders will work. They're not network related, even if they appear in the "Network" section.

Plus, Microsoft has released a hotfix for Windows XP. See: https://blogs.technet.microsoft.com/msr ... t-attacks/
