[Cryptography] NSA security guidelines for videoconferencing

[Peter Gutmann]

The thing with Zoom encryption is that in the current environment the threat
isn't Mossad doing Mossad things to you, it's preventing some random prankster
from inserting a dick pic into your conversation with your mother who's
worried about the fever your father is running.  It's the easiest - and given
that the alternatives are things like Microsoft's Skype, possibly only - way
for family members and the like to stay in touch via video during lockdown.
Zoom is addressing a usability issue, not a security issue.  If you need to
run sensitive conversations, don't use Zoom.

Peter.
