WannaCry Ransom Ware - It was Never About The Money

It was never about the money, only destruction.

Payments/Decrytion:
"“You’re really at the mercy of the human operator. Someone at the other end of the connection,” Hickey said.

The other problem is that WannaCry has no mechanism to determine who paid what and which computer should be released.

..But unlike most ransomware, WannaCry has no process to uniquely identify which ransom payment is tied to which computer, Horowitz said. Instead, users are left with a button on the displayed ransom note that says “check payment.”


Oh, and the encryption:
"But WannaCry does at least one thing well: Flawlessly encrypts all the files on an affected machine. Security sleuths are still studying the ransomware for ways to salvage already infected computers..."

"...The implementation of the encryption was pretty rock solid,” said Symantec’s Thakur. “There wasn’t any gap to jump in and get the files decrypted.”
