What the HEC? Security implications of HDMI Ethernet Channel and other related protocols - Andy Davis
VGA is dead (or at least dying), long live HDMI! The VGA socket on the back out your PC is 25 years old and with new PCs and laptops we’re starting to see a change – to HDMI, but under the hood this brings many other capabilities than just displaying video.
At Black Hat Europe 2012 I discussed the security of the EDID protocol which allows displays to communicate their capabilities to hosts over interfaces such as HDMI and VGA. I also touched on a number of other, very new HDMI-based protocols: CEC (Consumer Electronics Control) and HEC (HDMI Ethernet Channel). In this talk I will focus on the security of these protocols, how they will affect consumer network security and also their implications in the corporate world. I will also demonstrate a CEC security testing tool called CECSTeR.
