I got a call this morning from somebody claiming to be from BT. They told me that my home network was on the public internet.
To be honest I thought it was a scam. He was very insistent and rang back after I hung up. He sent me an email. I checked the headers and it seem to come from BT. The number he rang from had warnings against it as being fraudulent.
I rang the proper BT number. They weren't aware of the call I'd received. They said everything looks fine.
Anyway, the question remains am I really at risk? The router and all devices have an IP starting 192. I haven't changed anything so are there any other checks I can do?
