A) It's got to find a victim (IP range scans or whatever), then try to infect it. WannaCry used a vulnerability in SMB (CIFS/Windows file sharing) to get the virus payload onto a new machine and get it to run.
B) Once a piece of ransomware is running on your computer, it can generate an encryption key and send that back to its controller machine, then start encrypting files on the computer.
"A" shouldn't be able to happen on its own on a properly firewalled network, I think. So the start of the spread might be someone clicking an e-mail link that they shouldn't, and the infection works to spread on its own once inside a network.
