What hack(s) are you concerned about? I've seen a legit concern about the way the installer elevates privileges on Mac, but other than that I don't believe there have been any serious security problems. A little bit of privacy concern, but not security / hackability. Do you know something I don't?
The main features that I see that are missing so far vs zoom
control the screen
only cloud recordings
I don't see a way to set the password for your personal meeting id (it's there for scheduled meetings)
I don't see a way to lock the meeting
Improvements over zoom
browser client is very full featured computer audio, video, screen share (like teams)
I did a little poking and while by default you will likely connect with a very strong encryption (ECDH RSA AES256) for the WebRTC connection it does look like the server supports some weak cipher suites that would not pass HIPPA compliance that they talk about in the
whitepaper (TLS_ECDHE_RSA_WITH_RC4_128_SHA,TLS_RSA_WITH_3DES_EDE_CBC_SHA, TLS_RSA_WITH_RC4_128_MD5, TLS_RSA_WITH_RC4_128_SHA). I would feel a lot better if all the cipher suites had pfs.
