Attacking HDMI distribution networks: poster
Proceedings of the 12th Conference on Security and Privacy in Wireless and Mobile Networks(2019)
摘要
The High Definition Multimedia Interface or HDMI is the core and primary standard for Audio/Video communication in various media devices. HDMI allows flexible interaction between devices within HDMI distribution networks. Existing security standards and mechanism only protect traditional networking components. A user may mistakenly believe that a device is secure and an adversary may prove them otherwise. In this ongoing work, we show that by leveraging CEC to an attackers advantage. It is feasible for an attacker to reach devices which were formerly unreachable, and gain arbitrary control of HDMI devices. Specifically, we demonstrate it is possible to execute malicious device analysis, eavesdrop, and perform targeted Denial-of-Service attacks.
