I’ll hold my hands up and be totally honest, they probably got in because I am about as computer savvy as I am about Nuclear Physics, and considering I had trouble getting a grade D in CSE maths, that will give you a clue.
I didn’t know at the time that using admin access was a no no. I thought I was clever with the password but obviously not. I naively thought that buying a 2 bay NAS that what you put on one was automatically backed up to the other. I thought that was secure….but I now know it is not and I need another external drive to back up to.
Like you, I also sometimes access my music via a Sonos app on my phone to stream music around my house and I don’t know if that is done by UPnP or not… in fact, I didn’t and still don’t have a Scooby what UPnP is. People mention about port forwarding… they may as well be speaking Japanese to me as it means nowt.
I’m told don’t have the NAS connected to the internet… well all I know is that it is connected with a cable to my BT router… is that connected to the internet? I just don’t know.
So, as LMSC has suggested I have joined the SNB forum and will ask all my daft questions there and hope thay can guide me to a solution that means I can have it all back as it was, but also protected from the tw*ts who did this too me.
Sorry I couldn’t been more help…now, if you’d asked me about a good recipe for ginger cake… I’m your man.
