Security Advisory: ZoomBombing

The Olathe Public Schools like most school districts in America at this time is utilizing online meeting services such as Zoom.  Like all social media enhanced applications it’s very important to properly configure the service to avoid embarrassing situations.

Zoom Bombing is when you host an open zoom meeting and a guest connects and shares their screen containing questionable/vulgar content:

To prevent this :

You can either change this in your pre-meeting Settings or in the in-call admin settings for Share Screen -> Advanced Sharing Settings.

Anyone publicly sharing Zoom links where they could be discovered by trolls, like on Twitter, should be sure to change screensharing to “Host Only” before a call starts or as soon as they see the feature being abused.

  • Disable “Join Before Host” so people can’t cause trouble before you arrive.
  • Enabling “Co-Host” so you can assign others to help moderate.
  • Disable “File Transfer” so there’s no digital virus sharing.
  • Disable “Allow Removed Participants to Rejoin” so booted attendees can’t slip back in.
