How to Avoid the Latest Trend — ZoomBombing

— Written By

With the sudden increase in Zoom use as people in every walk of life move their face-to-face events online, there has also been an uptick in bad actors taking over Zoom meetings and creating chaos. The phenomenon even has a name… ZoomBombing.

A quick browser search will reveal numerous recent stories on this. The main thing you need to know is how to prevent it from happening to you.

For starters, not making your meeting link public on social media will help. For even more security, check out this post on the Zoom blog that describes a number of settings you can use to increase the security of your public meetings.

3/29/20 Update

NC State University and Zoom have implemented changes to default settings to help you exclude trouble makers from your meetings.

To increase the security and privacy of Zoom meetings, webinars and recordings some adjustments to the default settings for the NC State Zoom service were implemented. Note these changes only apply to meetings, webinars and recordings made after they were in place. You can implement these restrictions on existing meetings, webinars or recordings; see the support links below.
On March 26 Zoom changed the default screen sharing setting for all Education accounts. The default is now “Host Only”. This setting can be adjusted within a Zoom meeting or a user can change their default setting to apply to all meetings they create. For more details see Zoom’s notice.
On March 27/28 DELTA adjusted the authentication profiles available for restricting access to Meetings, Webinars and Recordings.
When scheduling a meeting or webinar, if the user activates the “Only authenticated users can join” checkbox, they will now be able to choose either “NC State users only” (the user must be signed into Zoom with an email address) or “Sign in to Zoom” (which only guarantees that the user is signed in to a Zoom account and not necessarily one in our account).
Recordings will have the same options when selecting “only Only authenticated users can view cloud recordings.” Note the default for this setting is on and set to “NC State users only”, where it was previously “Publicly.”
Users can change these settings on individual meetings/recordings or they can adjust their individual defaults. For more information see these support articles.
