Pirates cracked Widevine (and possibly other schemes). They have a drop-in replacement DLL (which they keep secret) that dumps the original content of the stream (not a screen / HDMI capture, like the other two comments said). This is called a WEB-DL, while capturing and encoding the stream is usually called a WEBrip.
- tbodt 7y agoThis doesn't work for Widevine L1, as L1 is handled in hardware. Windows has some interface to the Intel Management Engine used for this, Android OEMs write drivers and ship devices with keys, other platforms are out of luck.
- bscphil 7y agoThat's correct. Anything actually protected by Widevine L1 (meaning no workaround to get L3 instead) would require a different approach than just cracking the library.
- mrb 7y agoWidevine L1 has been cracked. Pirates gain code execution in the ARM TrustZone¹ and peek into the decryption keys of the widevine module. That's how 4k WEB-DL Netflix content gets pirated. ¹ For example: http://bits-please.blogspot.com/2016/04/exploring-qualcomms-secure-execution.html?m=1 http://bits-please.blogspot.com/2016/04/exploring-qualcomms-...
- baybal2 7y agoIf 4k netflix is what protected by their best hardware DRM, then... somebody managed to either exfiltrate the key, or drill the chip and get it extracted physically.
