Zoom-Bombing Prevention

If you are hosting a Zoom call with an Emory-sponsored Zoom account and the call gets Zoom bombed, please report the incident to the Emory Police Department by calling 404.727.6111 (TDD/TTY 404.320.1024) or by reporting the incident via LiveSafe.

What is Zoom-bombing?

Zoom-bombing is the term for when individuals “gate-crash” Zoom meetings. These uninvited guests share their screens to bombard real attendees with disturbing pornographic and/or violent imagery. Most of these are perpetrated via publicly available Zoom links; however, not all depending on your settings. Here are ways to protect you and your guest from falling victim.

Reminders on using Zoom to host public events:

When you share your meeting link on social media or other public forums, anyone with a link can join your meeting.

  • Avoid using your Personal Meeting ID (PMI) to host public events. Your PMI is basically one continuous meeting and people can enter and leave whenever they want. Learn about meeting IDs and how to generate a random meeting ID (at the 0:27 mark) in this video tutorial.
  • Familiarize yourself with Zoom’s settings and features so you understand how to protect your virtual space when you need to. For example, the Waiting Room is an unbelievably helpful feature for hosts to control who comes and goes.

Manage screen sharing

The first rule of Zoom: Do not give up control of your screen.

You do not want random people in your public event taking control of the screen and sharing unwanted content with the group. You can restrict this — before the meeting and during the meeting in the host control bar — so that you’re the only one who can screen-share.

To prevent participants from screen sharing during a call, using the host controls at the bottom, click the arrow next to Share Screen and then Advanced Sharing Options.

Manage your participants

Try the Waiting Room

One of the best ways to use Zoom for public events is to enable the Waiting Room feature. Just like it sounds, the Waiting Room is a virtual staging area that stops your guests from joining until you’re ready for them.

Meeting hosts can customize Waiting Room settings for additional control, and you can even personalize the message people see when they hit the Waiting Room so they know they’re in the right spot. This message is really a great spot to post any rules or guidelines for your event.
