Using WebGL while browsing with Tor? What could go wrong!

• coldtea 10y ago
  Nothing much. What do you think could go wrong?

    You get tracked, that's all. And perhaps linked to browsing on your default browser, without Tor. But maybe that doesn't concern you :)

    Letting a browser access video graphics processor is a terrible idea.
    • coldtea 10y ago
      It's also a useful idea if you want to have fast 3D graphics in your webapps. And the way you interact with the GPU is sandboxed anyway, and protected with various tactics (e.g. not enabled on known buggy cards etc). So? Not having access to the video graphics processor would be an even more terrible idea. And Tor is probably the most "privacy-theater" concept.

    I don't know, maybe massive pwnage? I'm sure you know that and are just being difficult. Its because OpenGL/DirectX drivers run a large compiler in the kernel and then send the compiled code to the GPU. None of that code is inspectable. Drivers routinely have special hacks to tweak the performance of particular games or matching patterns of use that tweak special paths, making thorough testing particularly hard. https://medium.com/@afd_icl/hey-a-web-page-just-restarted-my-phone-c06d3db76542 https://medium.com/@afd_icl/hey-a-web-page-just-restarted-my... https://twitter.com/alexstamos/status/829124727289544704 https://twitter.com/alexstamos/status/829124727289544704

      >I don't know, maybe massive pwnage? Any real examples besides proofs of concept and academic concerns? As in, examples that affect the average user, not some specifically targeted person?
