Zoom Bombing

As our use with Zoom increases each day, we have found an issue where uninvited guests can access your meeting—this is called “zoom bombing." Individuals have figured out that they can generate codes that are in the Zoom sequence. When they do this, they are randomly connecting to a zoom session.

How to prevent zoom bombing

  1. Generate a Random Meeting ID, rather than using your Personal Meeting ID.
    Avoid using your Personal Meeting ID (PMI) for meetings. Your PMI is essentially one continuous meeting and people can pop in and out all the time. Learn about meeting IDs and how to generate a random meeting ID (at the 0:27 mark) in this video tutorial.

  2. Set a Meeting Password
    This is the most critical component as no one can join without knowing this password. When scheduling a meeting, this option is available within the meeting settings that automatically pop open.

    If you use the New Meeting option to begin an instant meeting, you will need to sign into the Zoom Portal, select settings and verify they are set to require a password for instant meetings.

  3. Use a Waiting Room for Meetings
    The Waiting Room is a virtual staging area that stops your guests from joining until you’re ready for them. The waiting room is a great way to screen who’s trying to enter your meeting and keep unwanted guests out. Meeting hosts can customize Waiting Room settings for additional control, and can even personalize the message people see when they hit the Waiting Room so they know they’re in the right spot. This can be set within the meeting settings when scheduling a meeting, under advanced options.

    This Waiting Room video tutorial also walks through how to use the waiting room features.

  4. Manage Screen Sharing
    Don’t give up control of your screen, especially if you are hosting a public event. You can control this either before or during the meeting in the host control bar settings. 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.

    Settings are also available within the Zoom Portal. Select settings and select Host Only under Who Can Share?

  5. Additional Settings to Increase Host Meeting Control

  • Lock the meeting: When you lock a Zoom Meeting after it has started, no new participants can join, even if they have the meeting ID and password (if you have required one). In the meeting, click Participants at the bottom of your Zoom window. In the Participants pop-up, click the button that says Lock Meeting.
  • Set up your own two-factor authentication: You don’t have to share the actual meeting link. Generate a random Meeting ID when scheduling your event and require a password to join. Then you can share that Meeting ID through a public setting/social media and only send the password to join by email or direct message.
  • Remove unwanted or disruptive participants: From the Participants menu, you can hover over a participant’s name, and several options will appear, including Remove.
  • Allow removed participants to rejoin: When you do remove someone, they can’t rejoin the meeting. But you can toggle your settings to allow removed participants to rejoin, in case you remove the wrong person.
  • Put them on hold: You can put each participant on a temporary hold, including the attendees’ video and audio connections. Click on someone’s video thumbnail and select Start Attendee On Hold to activate this feature. Click Take Off Hold in the Participants list if/when you’re ready to have them back.
  • Disable video: Hosts can turn someone’s video off. This will allow hosts to block unwanted, distracting or inappropriate gestures on video.
  • Mute participants: Hosts can mute/unmute individual participants or all of them at once. Hosts can block unwanted, distracting, or inappropriate noise from other participants. You can also enable Mute Upon Entry in your settings to keep the noise down in large meetings.
  • Turn off file transfer: In-meeting file transfer allows people to share files through the in-meeting chat. Turn this off to keep the chat from getting unwanted content.
  • Turn off annotation: You and your attendees can doodle and mark up content together using annotations during screen share. You can disable the annotation feature in your Zoom settings to prevent people from using it.
  • Disable private chat: Zoom has in-meeting chat for everyone or participants can message each other privately. Restrict participants’ ability to chat with each other during your meeting. This prevents anyone from getting messages during the meeting.

All information is also available on the Technology Services Zoom Support site.

All district Zoom accounts must be made using your highlineschools.org email address.
