The initial attack was via email, through spam. These messages are typically fake invoices, job offers and other lures which are sent to random email addresses. Within the email is a .zip file and once clicked, that initiates the WannaCry infection.

The attack is then spread on internal networks with a worm which abuses SMB, a network file sharing protocol. Other aspects of the malware leverage file-less exploitation techniques, and the malware is morphing rapidly in the wild with over a dozen variants seen thus far.
