Most of the affected users won’t be able to uninstall the Zoom client in a clean way:

I could not get rid of the client in my process list for weeks and regretted installing it.

I will try the fix mentioned at the end of the article now (first killing the webserver).

They will have a hard time regaining users trust.

Just this morning we were on a Skype for Business call which, predictably, was a hot mess. We mentioned Zoom. I was on their home page. I was this close [ ... ] to installing it.

Now? I hope you're reading, Zoom. No chance now.

The sad thing is that Zoom will probably get away with not fixing this, or fixing it much later than they should.

If you look on Twitter, anyone that has complained about this (huge) vulnerability is being redirected back to their blog post.

To make things worse, most non-technical users that have caught onto these posts are replying to say "thanks for sorting it out!"

This wouldn't be the first time a company sweeps a data leak or vulnerability under the rug. I remember when the Panera Bread stuff kicked off, and all they had to do was bury their head in the sand and wait for the storm to pass. There's currently a lawsuit in progress, but will that happen for a vulnerability like this?

No amount of security features can rival a small piece of black tape over the camera. It also makes crypto-phishing (you've been recorded doing X, pay Y BTC) much harder to fall for. Where software could (and eventually will) be compromised, the attacker would have to physically access the machine to remove that tape.

One assumes that this activates the green camera light? It's not perfect but I can't imagine not noticing that it had come on.

Not that it helps if you're, ahem, in the middle of something when the nefarious 3rd party opens the line.

Why isn't the Windows client vulnerable? What have they/Microsoft done differently?

Safari asks you if you want to open an app that owns a URL scheme to prevent webpages from automatically triggering behavior you might not want. Zoom decided they know better than the Safari team and decided to install this local webserver specifically to bypass the operating system's security policies, supposedly because "it is their key differentiator" or whatever. Basically their product managers decided they want…

Those little tricks to make things easier is why it's popular and why they're currently valued at $25,000,000,000 (though that should go down quite a bit tomorrow, still just an insane number for a company with $8m in annual profits).

HIPAA provides an effective strategy for holding Zoom’s feet to the fire in cases like this. Since the company markets compliant video conferencing for healthcare professionals, they are classified as a Business Associate. It is quite likely that a well-written complaint on the HHS Office of Civil Rights site would result in further investigation and regulatory action.

Does anyone know of any working alternatives? We use Zoom a lot, it has the most hideous UI and the worst UX but so far it's been the only video platform that reliably works with tens and hundreds of attendees.

appear.in has worked well for me in the past.

Am I the only one seeing the pattern here. Most security loop holes I have witness have existed at the cost of providing a better user experience.

This is the security - usability tradeoff and is as old as the hills.

The fun thing is users mistakenly recognise the tradeoff as a sign of the security. If it was annoying it must be secure. Why would somebody waste my time for no purpose? See also placebo effect - of course I feel better, you gave me pills and I took them, duh, it's medicine.

Stock markets very rarely care about security, unless it's somehow front page news.

Investors would care if they thought Zoom’s customers cared enough to switch. I personally think this is terrible, but investors don’t seem to think Zoom’s customers care enough to change to a competitor, which makes me second guess whether or not this is actually a big deal to large customers.

my guess is this is of 0 importance to the stock market and large customers.

almost all video communications software works similarly to zoom, so that's that.

How do you recommend uninstalling this?

From the article: > To shut down the web server, run lsof -i :19421 to get the PID of the process, then do kill -9 [process number]. Then you can delete the ~/.zoomus directory to remove the web server application files. > To prevent this server from being restored after updates you can execute the following in your terminal: rm -rf ~/.zoomus touch ~/.zoomus

I did this: 1. killed by process name, and zoom app will 2. fail to start its opener and 3. fail to reinstall it:

  killall ZoomOpener
  chmod -x .zoomus/ZoomOpener.app/Contents/MacOS/ZoomOpener
  sudo chown -R nobody:nobody .zoomus/ZoomOpener.app
