If the camera was a client, uploading images or a video stream to a
server (which has a properly secured user side) how could the camera
be attacked? It will be behind NAT, for a start.
1. Attack server.
2. Use the server as a relay to attack clients that connect to it.
Or:
1. Attack some network equipment.
2. Spoof the server.
3. Use the spoofed server to attack clients that connect to it.
