|I have one web camera that I use for remote monitoring my home. It is configured to forward out port 8081 and my router is configured to do that. I can view it remotely just fine, and I use an Android AP on my phone to few the camera with my Android phone.|
My ISP uses dynamic IP and changes my IP address occasionally. I am using DDNS and access my camera using a host name, and I use their DNS servers. My router supports this particular DDNS service and seems to be working just fine. The Android AP uses naming and works just fine as well.
I get the typical port scans from China as just about everybody does. They focus on port 8081. My camera has a password, but it is only 7 characters.
The other internal LAN PCs are all protected with Antivirus and Malware programs. I have UPnP disabled on my router. The camera is on 24/7, but my other PCs only as required.
Since I have port 8081 forwarded, that “opens” the port to the Internet for anyone to try on that port. My only protection is the DDNS naming and 7 character password on the Web camera.
Given that I have port 8081 forwarded, am using DDNS, and the camera password is only 7 characters, is it possible for a persistent outsider to gain access to my camera?
Should they be successful, can an exploit be used to access my other internal LAN PCs?
