: More recently, critical vulnerabilities (like ZDI-CAN-30207 ) have been identified that could allow remote code execution via animated stickers or videos sent through the app. These are particularly dangerous as they require no user interaction beyond receiving the message. How to Ensure Your System is Patched

: Some IP cameras use QR codes for initial setup or network provisioning. Researchers have discovered vulnerabilities (such as those in certain Yi Home Camera models ) where a specially crafted QR code can cause a buffer overflow . If an attacker shows a malicious QR code to your camera, they could potentially execute code remotely and take over the device.

: If you use a DIY bot (like those for Raspberry Pi or ESP32-CAM ), ensure your code uses updated libraries. Developers frequently push security fixes to GitHub repositories to address API-related flaws. Best Practices for Secure Monitoring

Security risks associated with these technologies generally fall into two categories: exploits targeting the and those targeting the Telegram authentication process .

: In Telegram, set up a cloud password. Even if an attacker hijacks your QR session, they cannot access your account without this second password.

: Keep your IP cameras on a separate Wi-Fi network from your main devices. If a camera is compromised via a QR exploit, the attacker’s access to your personal data will be restricted. Talos Vulnerability Report

To secure your surveillance setup, you must apply patches at both the hardware and software levels:

: Never scan a QR code sent by an unknown bot or displayed on an untrusted website to "verify" your identity.
