Hey, I finally learned how to break widevine and managed to get some drm content decrypted. I did this woth tubi which was relatively easy. So, Next I would like to embark on the adventure of decrypting some paid streamings, esp. D1sn3y and H8O M1X. any tutorials on that? From what I tried, the process is not as simple as with tubi (maybe because tubi is mkre straightforwaed and free?). Anyway, Im eager to learn and would be grateful of any good guide on that. 🏴‍☠️

Edit: Okay, since I grasped bascics, now its getting easier and I managed to download some content from D1sn3y using N_m3u8DL-RE but only in 720p. Is it possible to get it in 1080p?

To decrypt 1080p content I would need L1 keys? L3 would not work? Technically, could I extract L1 cmds from browser and use those?

AFAIK, L1 are hardware backed using Trusted Execution Environment like ARM TrustZone. Unless you can find an exploit to exfil the key from the chip, you have no luck. It was done before and published, but I believe it is patched already. Anyone holding such exploit would keep close to their chest to avoid it beimg patched.

How would knowledge like this get shared in the scene? I'd imagine it would need to be passed somehow between teams, no?

Maybe. I'm not in the loop but I believe you would need to gain some solid trust from the core team to get that access. It won't be a knowledge just flows in the scene up for any newly join members to grab.

Oh for sure not. That would be so suscepticle to DRM-moles ;D

Yes, it won't work with L3 keys. As far as I know, L1 is different, you cannot just extract it without hacking it.

I never heard of L2 too so no idea. And yeah, you need physical device for L1. In some cases, you don't actually need the device, but the keys to decrypt the video.
