SmartTV StegoExfiltration: Hidden Data Transfer via Visual Steganography 🔍

This video demonstrates the Proof of Concept (PoC) for covert data exfiltration using visual steganography on Smart TVs. Developed as part of a Master's thesis in Cybersecurity at Universidad Católica de Murcia (UCAM), this project showcases how sensitive information can be hidden within a Smart TV's display and transmitted undetected to a variety of camera-equipped devices, such as tablets, Google Nest Hub, Amazon Echo Show, or security systems.

Key Features:
- Android TV app acting as the data transmitter.
- Cross-platform receiver application built with Flutter.
- Demonstration of data transmission using subtle changes in saturation that are imperceptible to the human eye but detectable by cameras.
