Tips on staying safe while using Zoom
"With the Coronavirus pandemic forcing millions of people to work, learn, and socialize from home, Zoom conferences are becoming a default method to connect. And with popularity comes abuse. Enter Zoom bombing, the phenomenon of trolls intruding into other people's meetings for the sole purpose of harassing attendees, usually by bombarding them with racist or sexually explicit images or statements."
The basics from the article are:
Make sure meetings are password-protected.
When possible, do not announce meetings on social media or other public outlets. But be aware that are automated malicious tools that try large numbers of random Zoom meeting IDs. So doing this by itself will not prevent incidents.
Carefully inspect the list of participants periodically.
Carefully control who can share their screens.
