Not that it matters since the miner *is* infected, but where do you see that this is a NH owned address?
The miner won't connect if the address is not owned by NH.
The last time I checked you could just plug in your external address and it would work. Did not know they ever changed it.
Using the 3BjMWfED7RJvtBPPikJpweDT6A9xRW952x address you posted when you google it, it's everywhere.
Using the 35TVW8JXxnrPviwyZoRbtNfs2RD1vXNRu1 address the OP posted when you google it there is no discussion about it. I would think if it was part of a large number of compromised miners it would be posted / discussed all over.
