What is Zoom-Bombing and how can I prevent it?

“Zoom-Bombing” is the unfortunate act of uninvited people coming into a Zoom Meeting and sharing unwanted content through various Zoom tools. Zoom-Bombing is a potential issue for all Zoom users, not just the Divison of Extension.

Here are the best practices for hosting Zoom Meetings which are open to the public.

Do all of the people included in my regularly scheduled meetings need pro accounts?

No. Only one person needs a Pro Account in each Zoom Meeting or Zoom Webinar.

Where can I find these Cheat Sheets I've been hearing about?

My camera has a microphone so do I need a headset?

We are asking that you use the headset. If you use the mic on your camera in a Zoom Meeting or Webinar with 2-3 people, you will likely not have any issues. However, with more people comes more potential for issues and feedback that can ruin the presentation for you and for others. The chances of feedback and garbled audio increased with each user. Sometimes even one person without a headset will unintentionally cause audio chaos. Don’t be that person.

Where do the green and pink plugs go?

If you have a headset with two plugs (one green and one pink) we recommend disposal. They served us well, but USB headsets are going to do a much better job. If you just can’t bear to dispose of technology, 3.5 to USB adapters cost about $7.

What if there’s audio feedback?

Have everyone put their headset on. Feedback is caused by a sound loop. The sound comes out of your speakers and then your microphone “hears” the sound from the speakers then sends it through to the other end. That happens again and again and again causing an echo sound or high pitched noise. If you separate the two sounds (say with a headset where the sound is going directly into your headphones) the feedback will stop. You avoid feedback in a conference room or group setting by using quality equipment that is designed to separate incoming and outgoing audio.

What is the difference between a Meeting and a Webinar?

In a nutshell, Zoom Meetings are designed for up to 100 people to have two-way communication. Everyone’s camera can be on and everyone can participate to their level of comfort. Webinars are designed for up to 500 people using mostly one-way communication. The host and presenters have active cameras and microphones; everyone else can only use the chatbox to communicate.

How do I set up a Zoom Meeting or Webinar from a conference room?

Your set-up for a Zoom just like any other video conferencing session.

Zoom Meeting Hardware:

  • A projector and flat surface/smart tv/Mondo Pad…you get the idea; you need to have a way to get the video from your computer to a bigger surface so everyone can see.
  • Computer- to run the Meeting
  • Camera- Zoom Meetings include two-way communication, so you need a camera to capture what’s going on in your conference room.  This is usually the element that makes or breaks the potential for good interactive meetings.
  • Microphone/speakers- for your incoming and outgoing sound. This could work with your conference calling phone system (the one use likely have for group Wislines), or be part of the computer set-up.

Zoom Webinar Hardware:

  • A projector and flat surface/smart tv/Mondo Pad…you get the idea; you need to have a way to get the video you are watching on to a bigger surface so everyone can see.
  • Computer- to run the Meeting
  • Speakers- so you can all hear what the presenters are saying

This seems like a lot of stuff. It can be, or it can be as few as 1 thing. There are lots of different set-ups that are going to get the job done for lots of different budgets. Most offices have a projector and a laptop computer. 

I need to call in from a conference room, what’s the phone number?

The phone number for a Zoom Meeting or Webinar should be included in the email you received telling you about the session. If it is not, please contact the organizer of the meeting. The organizer can find that info by going to zoom.us, logging in to their account and copying out the invitation for the specific session.  There will be 2 phone numbers on the invitation. You may use either number.

Is there an 800 number?

No. We will no longer be supporting 800 numbers.

How do I find my recording?


If you were the person to hit the record button, your recording is located somewhere on your computer as we are not using cloud-based recording at this time. Please check out this quick video to find recordings on your computer.

Accessing Local Recording Files

By default, all recordings will be placed in a Zoom folder found in the following file path on these devices:

  • PC: C:\Users\User Name\Documents\Zoom
  • Mac: /Users/User Name/Documents/Zoom

To access recording files:

  1. Open the Zoom desktop client and click Meetings.
  2. Click the Recorded tab and select the meeting with a local recording.
    Meeting recording settingUW Madison has very specific Recording Settings. Local, cloud, and automatic recording options are turned off by default. In a physical classroom, there is an expectation that people in the classroom are not being recorded. In virtual classrooms, this same expectation exists, and because it is not obvious when a meeting is being recorded there is a mandatory opt in feature that is in place for all recorded meetings. See https://kb.wisc.edu/105646 for more information.
