DRM explained - How Netflix prevents you from downloading videos?

[@ashishkashyap8231]

If anyone wonders how Netflix, Prime, or any platform's videos are still pirated: 1. Recording playback by tweaking the source code of the website, using certain extensions, or rooting Android devices to manipulate the "FLAG_SECURE" setting. However, this method results in low-quality video. 2. Recording decrypted HDMI output using HDMI capture devices like Elgato, which can be connected between a media player and a display/TV to record the output. This method provides high-quality video, even up to 4K. 3. There are different security levels (L1, L2, L3) in Content Decryption Modules (CDMs), as mentioned in the video. L3 doesn't run in Trusted Execution Environments (TEE), making it easier to extract from Android devices. With this method, users can download playback content in up to 1080p or 720p. 4. For some Android devices, the TEE has been exploited, allowing L1 CDMs to be extracted. Pirates may purchase these exploited devices to obtain L1 CDMs, which are then used to download 4K-quality content. 5. It is believed that some people have reverse-engineered the Chrome CDM but have kept it secret. In the past, there have been instances of Chrome CDM being reverse-engineered. For example, you can search for "GitHub tomer007 reversing widevine" to find a write-up on how the Chrome CDM was reverse-engineered. There are other methods as well, but the ones listed above are the most prominent and easiest to use.

[@crimsoncad3230]

DRMs cannot protect from virtualization and screen recording. Create a Virtual Machine, add your streaming service in it, record your screen from the main machine.

[@neerajbhale]

but playing the video on virtual machine itself will be limited to 480p as there is no hardware acceleration available with vm.

[@ultramondal]

I'm confused. What is VMGL?

[@sudiptapandit4880]

It can, there is no virtualization for TEE

[@ashwinsnmv]

​@@neerajbhale Hardware acceleration is available is many VMs now and its not limited to 480p. You can play upto 4k if you have a powerful system

[@NileshAkhade]

Are you sure? The DRM video cant be played inside VM. it stucks indefinitely. Even if it plays, recorded video wont show the DRM video, and the frame where video was playing will be shown as black box(similar to the example in this video). PS: I tried this with primevideo on windows10 vm hosted by Ubuntu.

There’s some hardcore engineering going on in the world, and folks here in India are chatting about DSA vs. dev! 🤦‍♂ Edit: Quite a few people in the replies clearly lack basic common sense and are getting triggered just because I mentioned DSA. They seem to think I’m saying DSA is useless, which I never said. By that logic, you could also infer that I’m saying dev is useless. What I’m really addressing is this absurd, baseless debate of 'either DSA or Dev.' If you’re pursuing computer science, DSA is a must-it's not optional. There shouldn't even be a debate about this.

[@DezsikeDevil1]

It's very easy if you're experienced enough. No matter how securely the file was encrypted, to play it back it must be decrypted. So the decrypted content and the key must be somewhere in the system memory. Software might not be able to access it, but if you tap into the data line of the memory chip, the key will eventually appear so you can grab it and decrypt the video yourself. Or the decrypted video will also appear. It's a time consuming progress to put it together from the pieces, but it's not impossible.

[@ronikagrwal]

Hey , can you do it for me please , i have purchased 1 batch's course but due to internet issues i can't stream it at my home , and it doesn't allow download , like it has in app downloads but has some glitch in it.. so it saves the file in a bin or maybe it's an encrypted format , so i want it in a video format . Can you?please!

[@DezsikeDevil1]

@ronikagrwal Unless it's a Netflix like thing it might not be as secure so you can do it in an easier way. You can check if you can catch the delivery of the key by pressing F12 on the page that plays back the video and reload. You'll see a bunch of things but one is the video link that should end in either m3u8, mp4 or ts extension and most probably will have a bunch of URL parameters. Or it could be an xml, manifest or something like that. If you inspect this you'll either find the key in there or a link to the license server that will serve the key. Don't try to open the link, it won't work! Instead, start the video and you should see the file in the link appear. Inspect it and it should contain the key. Use this key with a decryption tool like OpenSSL to decrypt the video file. The bin file might not the video you're looking for but the manifest file you've inspected earlier should contain the name of the video files or pieces of it. You can download these and use the key to decrypt them. Each video will have its own key but if one video is in pieces, the same key will work with all of them. I use this method to decrypt sport content from the government broadcaster (which is free so I'm not sure why they encrypted the video, but they did).

[@-din]

Of course, it's very easy to take a DDR stick and inspect every byte while it's still hot (data disappears shortly after it's disconnected from PC)

[@BennyJosephPerepogu]

[@its_mrad]

How to bypass drm protection very very easily : grab a firestick or any device with hdmi output, use a cheap hdmi to usb capture card 10 to 15 usd, plug into pc, open obs and record whatever you want

This wont work because TEE knows the HDMI device connected is not trusted.

[@czypherth]

​@@NileshAkhade it will work if you change it from firestick to a chrome based streaming service because its only L3 TEE

I know there are harder solutions like fingerprinting could be a good idea to add to your solution too.

[@sudiptapandit4880]

Virtualbox cannot talk to the hardware chip based TEE, and for HDMI there is HDCP , for widevine L1 both are required. You can capture only L3 at max

Back in 2014, I once downloaded a movie using Showbox on my Android device. While going through the files, I noticed that it had downloaded all the frames, each as a tiny file of just a few kilobytes. had to stitch them all together, but there were thousands of files, and I eventually gave up halfway. not sure if Netflix on Android still does that.

[@chetankumar9463]

Maybe you recorded HLS file. This format is used for streaming videos.

[@lekipising]

This is good. Been looking for this content on DRM

[@lucaciandrei]

with this, you can also get an undesired bug on macs running the m chips, and which make use of docking stations with displaylink technologies. since mac treats the extensions of screens on displaylink technology as "your screen is being observed", meaning the flag is triggered, if you wan to play netflix on your secondary screen, it will play it blank. pull out the docking station and the video will play as expected... so this thing is tricky altogether.

Correct me if I am wrong but doesn't this become redundant if you have a capture card connected to your display driver. So you let the DRM do the decryption and just consume the audio and video streams directly.

[@cloudstrife9204]

Yea even I thought this was a work around . You could also read from a HDMI port like on a tv and reconstruct the video , I think this is called webrip format in the torrent world. Atleast this method helps that video is not torrentable before a legitimate user is able to watch it, just saves some time. I still think some people still able bypass it

[@thanatosjamie7663]

This doesn't work because the TV manufacturers also implement DRM. Look up HDCP. HDCP prevent other devices from copying the video stream. Of course workarounds exist, but most people are not aware of them.

[@ArtVorobyov]

[@InsipidTawfiiq]

You explained a complex topic very simply. Kudos!

[@angshulsana]

You said how it manages to play, but WHY it gets BLANK WHEN WE RECORD IT?? And You're correct that Chrome's DRM (Digital Rights Management) typically limits Netflix playback to 720p. However, Netflix uses additional technologies to enable higher resolutions: Netflix's 4K playback requirements: 1. Widevine DRM L1: Required for 4K playback. Widevine L1 is a more secure DRM level. 2. HTML5 Premium: Netflix uses HTML5 Premium to deliver 4K content. 3. Google's Encrypted Media Extensions (EME): Enables DRM-protected content playback.

[@ArtVorobyov]

If I get what you asked, TEE see some traces of video recording software through metadata it consumes and returns grey picture frame instead of decrypted one. But as far as I've got, you are better with this kind stuff, so you already know the answer.

[@playernoob1249]

Only 480p playback is visible to user processes which is decrypted by L3 as software plugins. L2 and L1 which is 720p and above are decrypted in OEMCrypto module in TEE which makes the rendered stream invisible to all user processes which includes recorders, L1 goes one step further makes it invisible to OS itself.
