Hi,
after seeing the IP address of your server in the first email (which by the
way was sent out to all subscribers of this Google Group), it looks like
you have (well, had) an unsecured MongoDB instance running which has been
wiped by a third party.
$ mongo "${YOUR_IP_ADDRESS}:27017"
MongoDB shell version v3.4.0
connecting to: mongodb://${YOUR_IP_ADDRESS}:27017
MongoDB server version: 3.2.5

I'm afraid your only chance is to restore a backup of the configuration,
which you hopefully have, and secure the MongoDB database properly.
Please
read
https://www.bleepingcomputer.com/news/security/mongodb-apocalypse-is-here-as-ransom-attacks-hit-10-000-servers/
and
https://www.mongodb.com/blog/post/how-to-avoid-a-malicious-attack-that-ransoms-your-data
to understand the issue at hand.
Cheers,
Jochen
