      Zoom uses the SILK codec, Constant Bit Rate (after some bandwidth negotiation); as others have pointed out audio and video noise both fight ECBs weaknesses. It’s actually more secure on the wire than many conferencing systems I’ve looked at.https://twitter.com/colmmacc/status/1246160773379796994 …

      Folks are hating on Zoom for using ECB encryption, but has anyone checked if it uses variable bit rate audio, or silence suppression? Both make it trivial to decipher spoken words, using very boring traffic analysis. I've seen many VOIPs and VideoConfs make this mistake. https://twitter.com/AaronToponce/status/1246153323649970176 …

      “more secure than many” doesn’t feel like the bar Zoom should be shooting for? Vs eg “secure” or “transparent about the tradeoffs it makes”, etc?

      I'll put it this way: if someone were tapping my Internet connection, I wouldn't be so worried about them able to decrypt a Zoom call. Meanwhile there are solutions out there where it could be an undergrad project.

      This is an interesting and valuable viewpoint. Imho It is unfortunate that Zoom didn’t put out docs describing this or similar perspectives (eg, positive evidence of the end-to-end security of their approach) months/years ago.

      Similarly to how if Amazon-the-web-store had put serious dollars into lobbying for universal sick pay in previous years maybe the current warehouse situation (both ground truth and press) would be less bad?

      More aspiration-ally, I'd say similar to how much better we'd all be here if the US were a credible and legitimate democracy that didn't foster that kind of corrupt lobbying or outsize influence of corporations.
