Soooo this was written before the explosion of Zoom use…and subsequent bad pr over the security issues…yet they haven’t really made the switch?

Your article has confirmed for me that I want to keep my Chromebook..I’ve loved them for nearly a decade but was super frustrated by the limited ability to use Zoom. It is for my own good!

Great post, thanks for sharing. From my understanding and research, Zoom are using H.264 SVC as their codec.

John,

That’s one definition of hacking, which is mostly related to security breaching and not money – at least not directly.

Hacking is about finding your way into a software system in ways that aren’t documented, expected or supported. It is at least what I meant in that use of the word in this article.

Hacking is about making money, where’s the money to be made with having someone join a video meeting

In reply to Göran.

Well… they didn’t intentionally create zero-day vulnerability. They created a feature that could only work architecturally if they hacked they way through Apple’s Safari sandbox. That, in turn, was implemented in a way that was vulnerable to different types of attacks.

The publicity of this, along with the potential security risk, led Apple to remove the app remotely.

This sounds really fishy and strange. Zoom actually created their own zero-day vulnerability, which now Apple remotely removes from users computers, how is that possible?

Mind you that after muting your own camera in a webrtc app, the app has the ability to unmute it without needing confirmation (i.e. a button click) from the user.

Could a WebRTC app implement a remote unmute feature? Totally…
