back to article Wondering how to whack Zoom's dodgy hidden web server on your Mac? No worries, Apple's done it for you

Apple has pushed a silent update to Macs, disabling the hidden web server installed by the popular Zoom web-conferencing software. A security researcher this week went public with his finding that the mechanism used to bypass a Safari prompt before entering a Zoom conference was a hidden local web server. Jonathan Leitschuh …

    So is the poor user experience due to Apple's API/security model or Zoom's inability to program? And is there a hidden webserver on Windows installs?

      Its to prevent Zoom users receiving a prompt for the website would like to use the microphone and camera.

      According to the previous news post there is no such web server on Windows and I think a commentor confirmed Linux users don't have the web server either.

        :-O Those prompts are there for a f*cking reason.

          Yes, trying to educate normal users to actually read the damn messages is hard sometimes (I have had a few times the "I have nothing to hide" response like its the police being given those priviledges and not some huge blood sucking corporate company).

            Are we sure users were even asked if they thought it was a "poor experience" or is this simply Zoom doing this so they have an advantage over the competition then claiming it's all for the good of the user?

    > Further, Zoom promised an update in a couple of days intending that users who select "Always turn off my video" on first use will have that preference saved automatically.

    Is it just me who feels that "Always" implies "Always" and not saving the preference rather conflicts with the description?

    I'd say I cannot believe people like this would be allowed near a computer, but clearly they have been. If you're actively coding round standard security practices, you are no better than malware writers.

      Which is probably why Apple treated it as malware

      And removed it from all Macs. Then users who installed it but rarely use it won't have a web server written by a company that doesn't understand security running on their computer, and users who want to keep using Zoom can simply reinstall the newer fixed version.

        Re: Which is probably why Apple treated it as malware

        they only removed the web server. Not the whole software suite. I agree with other posters. Stuff from that company is not getting onto any computer of mine for a good long while and possibly longer

    I've set up a virtual webcam with customised fake video, configured to always get picked before my actual webcam [1]. Anyone incautious enough to try cam-snooping on my machine is going to get a surprise!

    "Apple appears to have concluded that it is better to protect users by silently disabling this component than to respect the wishes of those who like to think they are in control of what gets installed and removed. Few would disagree."

    I understand that in the browser some local javascript to "localhost:<someport>" can make a POST to zoom's installed local (API) web server and execute some code locally; still not sure how that code (C, Swift, Objective-C, etc) can instruct the safari browser to enable the webcam. Is this possible with AppleTalk? Sounds hacky.

    Or is this web server / client connecting to the zoom conference server directly, effectively not really even using the browser once started... In that case, this is just another case of everyone over-utilising a web browser as just a shite GUI library.

    The whole thing sounds terrible. You wouldn't get this kind of mess in less popular software ;)

      <guess>I don't know the specifics. But my guess is this javascript using the media capture API. If a web site uses it, the browser prompts. But the localhost is probably exempt. So if you serve your page from a locally installed web server - there's no "annoying" prompt.</guess>

    Now that's a good unprompted user experience. Maybe Zoom could learn a thing or two from Apple.

    Companies like this need to go out of business.

    Security must not a an afterthought and these clowns clearly have no idea about security.

    1. gnasher729 Silver badge

      It is quite possible that a company has engineers that are competent and care about security and are overruled by management who has received complaints from customers. (Customers will complain because they _wanted_ a connection and didn’t think there should be another prompt, oblivious of the fact that this prompt protects against hackers).

    Almost a good thing

    Except I'm on a corporate box and refuse to provide my credit card number to Apple which means that Apple updates NEVER get to my machine...

      Re: Almost a good thing

      This **** is on the same level of retardation as "I don't do math".

      Just move to Linux if you honestly never want updates etc and stop wasting money on poor value for money hardware.

        Dude, if your company is making your pay for the box you work on, you ought to consider changing jobs.

      Why lie like that? You don't need to give Apple a credit card number to get updates.
