The "remote attack" is to connect to the node and request to download the blockchain. Sounds like the protocol working as advertised.
in a way that isn't sensibly rate limited and can cost thousands in upstream overage fees - which is why dogecoin is preparing a fix..
It already has the "fix" inherited from the Bitcoin code they reuse. Though you shouldn't count on that feature to not have bugs: the Dogecoin codebase is old and poorly maintained. If you run it on a cloud service, always turn on billing limits. https://github.com/dogecoin/dogecoin/blob/master/doc/reduce-...
