FYI to anyone who might be affected, there's a somewhat palatable "workaround" to prevent this from completely consuming your data:

Synology disk HACKED (Synolock)

If you remove your disks from the NAS, boot to an empty/clean single disk, install DSM to that disk, shutdown, and replace the old disks, it can update the firmware without corrupting your personal data.

That being said, it appears the Synolocker loads into a local Linux module, sits in memory, and blocks access to the admin page. If you get the message on your admin page, you shutdown the NAS and your data might be safe. It appears that accessing the data via UNC despite the admin page message proves the data is not immediately affected.

Thanks for the tip.
