Hi Guys,
A courtesy post to say a final thank you.
- UPnP proven as the cause
- UPnP disabled on both router and NAS (I don't need media streaming internally - it's a backup device)
- Manually initiated Shields Up attack on my own external I.P. address revealed no weaknesses
- Both disks in the NAS "reformatted" to destroy all data (albeit by switching from RAID 1 to RAID 0 and back to RAID 1)
- Wire Shark installed and which confirms nothing trying to report back to base or any other kind of suspicious network activity
- MioNet remote access service now disabled (Not the cause of my troubles but a potential future weak link removed)
- NAS loaded with non-personal files and left running all night; this morning it was in standby mode and the logs show no activity overnight (they can be scrubbed, yes, but given the above I trust them)
So, other than a small number of files (I reacted quickly) which *may* have escaped from my network and which there is no point worrying about (all files were in a private secure area that would have needed hacking in to, it's too late now, and I don't know if the hack actually did anything anyway) I don't think any damage was done.
Time to move on.
Fresh backup to NAS running as I write this.
"Cheers Guys"
