Explore security vulnerabilities in DVB-C networks during this Ekoparty 2014 conference talk. Delve into the intricacies of Digital Video Broadcasting - Cable systems, including MPEG-2/MPEG-4 stream transmission and QAM modulation. Examine potential attacks on DVB-C infrastructure, covering topics such as hijacking TV streams through middleware server vulnerabilities, exploiting implementation bugs in network protocols for man-in-the-middle attacks, and fuzzing setup boxes via MPEG streams. Witness a demonstration of taking over Cable TV broadcasting and gain insights into both analog and digital network architectures. Learn about QAM modulation, frequency collision avoidance, setup box management, and the role of middleware servers in remote device control. Understand the concept of transport streams and investigate firmware update processes in the context of DVB-C security.
