Changing programming access levels on 9100

Changing programming access levels on 9100

Changing programming access levels on 9100

(OP)
A colleague mentioned they recently had a system hacked. Customer was using port forwarding (changed port from default) and hackers got into the system using the NECII login name (password had been changed from default too).

The hackers got into the DID and call forwarding tables and routed calls overseas. They then went in a couple days later and changed it back. Colleague was able to see in the modification history what areas of programming they got into.

He has since wiped out all user login names to try to prevent it from happening but, is it possible to change the NECII account to "prohibited" user before logging out and then be able to set it back to "manufacturer" or once it is set to "prohibited", it won't have access to change it back?

Other option is the try to change the username NECII to something different. Don't like messing around with that account just in case we can then not get back in to correct it. Be something to play around with on a new system where it could just be factory reset.

RE: Changing programming access levels on 9100

Quit port forwarding on an open internet connection. Use the 9100 callout feature for PCPro. Restrict that port to a fixed IP address only. Of course change the passwords but no matter what you do if you port forward to ANY on the internet you are going to get hacked.

RE: Changing programming access levels on 9100

Changing passwords on an NEC is pretty much futile as they are numeric only and so easily hacked. Change the user names as they can be as complex as you want!
