I do not understand why hackers trying to hack my website since this website is for educational purposes and no commercial value.

Even website like mine draw their attention, what more if you are running your PBX in the cloud. You could be VoIP hacked and lost up to millions of dollars (ringgit). Well, if your SIP trunk runs on the cloud and does not go through a proper VPN, you are at risk. I know quite a number of organizations’ phone lines been hacked and they will need to pay hundreds of thousands to their line providers. These organizations are keeping quiet with the phone vendors because it is so shame.

There is certainly a lot to find out about this subject.
I love all the points you made.
