How to check packets on Not Attached Wireshark

I am currently running Windows 7 VirtualBox on my Windows 10 host. However, I do not want to connect them to each other since I need to check the packages being transferred when WannaCry is running. So, is there any way of safely attaching my computer to any of the options without WannaCry sending packages outside of the VirtualBox?
