Fresh hacks every day
There’s two really useful parts to this hack which involves sniffing the HDMI protocol’s HDCP security keys. The first is just getting at the signals without disrupting communications between two HDCP capable devices. To do so [Adam Laurie] started by building an HDMI breakout cable that also serves as a pass-through. The board seen above is known as an … Read the rest
[bunnie] is up to his old tricks again. He successfully implemented a man-in-the-middle attack on HDCP-secured connections to overlay video in any HDMI video stream. There’s a bonus, too: his hack doesn’t use the HDCP master-key. It doesn’t violate the DMCA at all.
HDCP is the awful encryption scheme that goes into HDMI-compatable devices. Before HDCP, injecting video overlays … Read the rest
It’s been a little while since we talked about HDCP around here, but recent developments in the area of digital content protection are proving very interesting.
You might remember that the Master Key for HDCP encryption was leaked last year, just a short while after Intel said that the protection had been cracked. While Intel admitted that HDCP had been … Read the rest
Pastebin has the HDCP master key that we talked about in a post last week. This is the encryption protocol used for HDMI content protection on media such as Blu-Ray and High Definition cable television.
The master key array is a 40×40 set of 56-bit hex used to generate the key sets. You get one brief paragraph at the … Read the rest
Intel says that HDCP has been cracked, but they also say that it’s unlikely this information will be used to unlock the copying of anything. Their reasoning for the second statement is that for someone to make this work they would need to produce a computer chip, not something that is worth the effort.
We question that logic. Not … Read the rest
Reader [GRitchie] wrote in with an interesting find in his new TV set: with just some minor soldering it was possible to tap into an unencrypted hi-def video stream.
HDCP (High-bandwidth Digital Content Protection), used by Blu-Ray players and cable or satellite receivers, normally ensures a DRM-protected link between the device and a compatible display. Any properly-licensed device that … Read the rest
