Parse Server & Parse Dashboard Security

[dhavalyours]

Hi,

Our parse hosted mongo setup was hacked similar to bug #3334

This hack was a type of extortion. The entire db was deleted and following message was there in the error logs

insert PLEASE_READ.PLEASE_READ query: { _id: ObjectId('587026363592359314ee86fc'), Info: "Your DB is Backed up at our servers, to restore send 0.1 BTC to the Bitcoin Address then send an email with your server ip", Bitcoin Address: "1J5ADzFv1gx3fsUPUY1AWktuJ6DF9P6hiF", Email: "kraken0@india.com" } ninserted:1 keyUpdates:0 writeConflicts:0 numYields:0 locks:{ Global: { acquireCount: { r: 2, w: 2 } }, MMAPV1Journal: { acquireCount: { w: 8 }, acquireWaitCount: { w: 2 }, timeAcquiringMicros: { w: 81 } }, Database: { acquireCount: { w: 1, W: 1 } }, Collection: { acquireCount: { W: 1 } }, Metadata: { acquireCount: { W: 4 } } } 447ms

This is a serious issue

Since then we have take following security actions on our hosted instance server

1. Running mongo on different port rather than default port.
2. Closing public port to access db.
3. Separate read/write credentials to parse application to use db.
4. binding mongodb to localhost only.

Is there anything else we can do to secure our mongo instance ?

The current parse setup runs with master key & api key.

If someone might get hold of it they can manipulate the db using parse Apis. Is there any way we can implement additional security to our hosted parse instance ?

Look into class level permissions and ACL they are utterly important to prevent unlawful read and writes. Your master key should be private, don't hesitate to rotate it regularly if you believe there was an issue.

After that, all security best practices apply. We recently added password validation etc... to parse-server, you may wanna look into it for securing your private data.

I don't see any mention of auth or TLS in the actions you took. This is definitely something you should consider. Also, have a look at the blog post from Mongo on how to deal with this situation https://www.mongodb.com/blog/post/how-to-avoid-a-malicious-attack-that-ransoms-your-data

One thought I had about the data, maybe the hackers didn't drop the oplog? If it's the case, you might be able to get some data back. Have a look in local.oplog.rs...
Even if the oplog hasn't been cleared, it won't be easy to recover from it (it's pretty technical and I can't help with that) but at least it's something that might be useful...
