Any resources on Level 1 decryption?
- m-p-3 6y agoIt's probably kept under wraps by large scene groups, they don't want to show their methods and have them patched out.
- gruez 6y agoOne method appears to be playing back on a legitimate player, then using HDCP strippers on hdmi/displayport outputs[1]. I've seen some 4k releases that clearly show the streaming site's playback controls, for instance. [1] search for "hdcp bypass" on ebay
- mmm_grayons 6y agoI remember cheap chinese hdmi splitters used to inadvertently strip hdcp; is that still current?
- dannyw 6y agoYes, but you could just explicitly search for a hdcp stripper and it'll work.
- bawolff 6y agoThere have been a bunch of papers recently about using undervolting to break secure enclaves. No idea about how applicable that is, but that might be a possible attack vector.
- snvzz 6y agoCapture HDMI. Strip DHCP. Refer to the perfectly legal NeTV2 + trivial modification if you understand the HDL.
- Thorrez 6y agoIs that considered decryption? Wouldn't that both decrypt and decompress? What if someone wants the original compressed stream so the video doesn't need to be re-compressed?
- bscphil 6y agoThat can't be done without hardware hacks, which can (often) be traced to isolated hardware which the manufacturers will then lock out or force a software upgrade for, making it impossible to use in the future. That's why most 4k pirate releases are re-encoded from HDMI, not lossless rips of the original stream as they are for 720p and 1080p.
