Dear user,

So it looks as though someone is trying to hack into my network/NAS. Initially I thought I may have left port forwarding set up in my BT Smart Hub to direct SSH to my NAS, but I do not and currently have no port forwarding configured. So the question is, how can people be connecting to my NAS in the first place? And if this is happening, what other attacks might be going on?
My other thought is that this may be some nonsensical message being sent from my NAS, which does update itself fairly regularly.
