    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.

    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.

    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
      @DezsikeDevil1 Месяц назад

      @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).

    That's really good explanation! Though it's funny that all of this is evaded with just Virtualbox 😅 and I think there are devices that can capture the monitor's HDMI output doing it on a hardware level. I know there are harder solutions like fingerprinting could be a good idea to add to your solution too.

    • @sudiptapandit4880

    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.

    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.

      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.

      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.

    how does firefox play drm video then, does it ask some OS layer software to do this ( is this the reason firefox does not play netflix in linux) because firefox is opensource right? also you did not cover the video recording part, how does the browser knows when the screen is getting recorded ?

    This is super interesting, I always wondered how this works.
    How does it detect if there’s a screen recorder running? I assume that’s some feature of the TEE being able to detect certain applications? I would expect that to need some kernel level code thought (that’s just a guess)

    • @playernoob1249
      @playernoob1249 Месяц назад +1

      It doesn't detect screen recording.
      content processing, cryptography, and control happens within the Trusted Execution Environment (TEE) of the processor which makes the media playback invisible to all the other processes including OS, That's why screen recorder sees it as black box

  • @shugyosha7924
    @shugyosha7924 Месяц назад +1

    All this effort they go to, but at the end of the day the content is playing on the screen - you just need a way to screen capture without being seen by the TEE. Kernel or hardware level interventions, VMs, physical cameras, it's impossible to block.

  • @Lalit-yw2tb
    @Lalit-yw2tb 2 месяца назад +1

    Wait, since information exchange happens with the widevine server, won't those calls be visible if we intercept them through wireguard? It doesn't matter if the decryption happens within the secure environment. Won't it be possible to intercept those requests and try to reverse-engineer/ see the payload returned by the widevine signing server?
    Right?

    • @playernoob1249
      @playernoob1249 Месяц назад +1

      It's possible for only L3, L2 and L1 keys are only usable in requesting device keybox(part of OEMCrypto) for that playback session only. In L1 and L2 not even CPU has access to decrypted clear keys. Widevine is nuts

  • @chrishamilton1728
    @chrishamilton1728 Месяц назад +3

    None of what you said explained why the screen is black when recording - that's probably just JS or CSS that can be easily disabled lol
    After TEE has done the decryption, they can't stop you from capturing it - it's there in your memory registers.

  • @namangupta86
    @namangupta86 Месяц назад

    But, you still didn't tell the reason why we can't record the video through video recording/capture software.
    Its fine that the vudeo is playing in a drm protected video player. But, what is stopping the screen capture utility to record that? Why aren't we able to make the drm software beleive that there is no screen recording software?
    What about passthrough HDMI capture devices? Is netflix able to block that too?

  • @frcl
    @frcl Месяц назад

    I once read on some OpenGL topic a feature where a buffer gets displayed so fast that it makes it "exclusive" to the main hardware display and there is no way a software can intercept the data
    and it said it was the feature perfectly fits for DRM technology to utilize, is this the hardware acceleration feature?
    i cant pinpoint the site but this is what I recall please enlight me if im wrong

    DRM is powerless against me recording the HDMI output of a media player ☺️ OK, so it's a real-time process, but as someone who grew up in the 70s/80s, that's how recording video always was, so it doesn't bother me!! FWIW, this isn't something I do very often, but once in a while there's something I need/want to record 🤷‍♂️ HDCP strippers are easy to find. Most HDMI splitters deal with the handshake and send out two "clean" HDMI signals.
