Exact motive for hack attack will likely remain speculation.
Here’s what’s known via latest update from Krebs:
https://krebsonsecurity.com/2017/06/petya-ransomware-outbreak-goes-global/#more-39734
The latest information about update:
1. It’s not Petya, although it may be by the author of Petya. It’s even being called “NotPetya”.
2. There is no kill switch, but the program checks for the presence of a file called “perfc” in c:windows. If the file is present, the ransomware at least does not run.
3. Posteo in Germany have closed the email account that was the sole point of contact for those infected. So now victims don’t have any hope of getting their files back unless they have a complete backup.
4. As well as ETERNALBLUE the authors are using a second NSA exploit, ETERNALROMANCE.
The panic is somewhat overdone unless of course you’re working for a large organisation with thousands of endpoints. The infection phase is almost certainly over now and it won’t spread outside infected networks.

“Here’s what’s known via latest update from Krebs:”
So Maynard got into computer science? Work?
I work for a very large corporation.
There were a few clusters of un-patched systems that got clobbered.
But most machines were never infected by WannaCry.
It’s time to SUE those corporations that do not patch their systems to current standards and have inadequate perimeter security and procedures...if they end up denying paid-for services.
The hackers will always be there. The REAL problem is lax security on the part of corporate networks.
