Yeah, but pirate groups are getting the original streaming service's compression without re-encoding (so-called "WEB-DL"), even of 4k content. There's a weaker link somewhere.

WV L1 Keys/ PR SL 3000 keys require breaking into the TEE to steal those decryption keys.

Ever wondered why netflix 4k web-dls take a while for less popular shows?

Netfliy monitors these more tightly apparently and blacklist keys that are used to download. Then the group needs to buy some new device, the old one is burned.

It's true that known-compromised keys get revoked, but it's possible to avoid them knowing you've compromised a particular device.

I think there's some kind of watermarking going on, so once a rip is released to the public they can trace it back to which device keys were used to decrypt it.

Interesting, I hadn't heard about that. But this knowledge is obscure by design I suppose.
