Telegram and camera manufacturers have recently implemented several measures to address the unauthorized sharing of these feeds:

Instead of port forwarding, use a personal VPN to access your home network securely.

When a vulnerability is described as "patched," it means the manufacturers (such as Hikvision, Dahua, or generic Tuya-based brands) have released firmware updates to close the specific security hole. These patches typically involve:

: When a user scanned the malicious code using the Telegram app, it injected forged credentials, allowing the attacker to hijack the active session and view camera streams without needing a password or SMS verification.

From a broader cybersecurity perspective, this case highlights the "Internet of Things" (IoT) security gap. Many devices remain unpatched because users rarely update camera firmware, leaving millions of devices vulnerable to QR-based hijacking long after a official patch is released.
