JavaScript DRMs Are Stupid and Useless

6 hours ago

HotAudio.net offers DRM for ASMRtists, but it's JavaScript-based and fundamentally vulnerable.
JavaScript DRM is flawed because the decrypted data must eventually be accessible to the browser, making it interceptable.
The article describes a cat-and-mouse game between the author and HotAudio's developer, involving various techniques to bypass and patch DRM.
Key vulnerabilities include the 'PCM boundary' where decrypted audio data must be handed to the browser, and the use of JavaScript hooks to intercept this data.
The author developed multiple versions of a browser extension to bypass HotAudio's DRM, each countered by the developer with new defenses.
The final version of the extension uses deep hooks into browser APIs to intercept audio data regardless of where it's played in the DOM.
The article argues that JavaScript DRM is inherently weak and cannot provide true protection, unlike hardware-backed DRM solutions like Widevine.
The author concludes that while DRM may offer some friction, it doesn't effectively protect content and may not serve creators well.
The article emphasizes the importance of open and accessible internet, while acknowledging the economic realities that drive DRM adoption.
