If you have got a Huawei 633 "super router", its nowhere near as bad as many reports make out, though I intend to replace it with a tp-link for a bit more flexibility.
I've had a non-stop hacking attack for a while, every 10 minutes something/someone has a go at port 23 (telnet) and now and then it does a few other bits and pieces.
You'd think that after a month or two they would realise my port 23 is closed, I have a cctv
server which is what they are trying to hack into. The only inconvenience to me is the logs filling up.
I guess the source IP is spoofed, it alternates between Armenia and China ..... so its probably the next door neighbours
