Privacy & Security Concerns with Tips

"ZoomBombing" - Meeting Room Hijacking

There  have  been  many  cases  of  unwelcomed  individuals  joining  meeting  rooms  and sharing  inappropriate  material  via  chat  or  webcam.  This  has  become  known  as  “Zoom bombing,”  and  meetings  hosted  by  education  institutions  have  been  the  primary  target.

The  recommended  solutions  will  be  briefly  covered  and  a  link  will  be  provided  to  the relevant  Zoom  Support  article.


Recommendations to avoid "ZoomBombing"

General Guidelines

  • Use a unique Zoom  ID  for  each  meeting,  avoid using your  Personal  Meeting ID.
  • Do not post  meeting links  on social  media.
  • Do not share links  to  meetings  you are invited to join without  the host’s  approval.  The host  can send more invites  to the relevant  individuals  or  parties.


Manage Participants as the Host

As  of  April  6,  2020,  Zoom  has  enabled  waiting  rooms  and  meeting  passwords  by default  on  free  accounts,  education  accounts,  and  single-license  accounts.
