This is exactly why network segmentation is critical for IoT devices. I always recommend putting all smart cameras and IoT devices on a separate VLAN with no direct internet access - only local network access through a firewall with strict egress rules.
For anyone concerned about their TP-Link cameras, consider:
1. Disable UPnP on your router
2. Use VLANs to isolate IoT devices
3. Block all outbound traffic except specific required endpoints
4. Consider replacing stock firmware with open alternatives when available
5. Regularly check for firmware updates (though as this article shows, updates can be slow)
The hardcoded keys issue is particularly troubling because it means these vulnerabilities persist across the entire product line. Thanks for the detailed writeup - this kind of research is invaluable for the security community.
