What is a Zoom-bomber?

Zoom is a synchronous (live) web conferencing tool that is fantastic for fostering meaningful instructor-student and student-student interactions. It is being used by many faculty to assist them with a smooth transition to temporary remote teaching and learning. 

However, in this time of disruption, there has been an increased likelihood that you may have uninvited attendees show up in your meetings and deliberately try to derail it. During the COVID-19 period, educators and businesses alike are reporting incidents of “Zoom-bombing” or “Zoom trolls.” The following tips are provided to help you continue with your synchronous instruction in Zoom without the burden of uninvited attendees.

Zoom Bombings are divided in to 3 main groups

Visual Attacks: These include inappropriate imagery via virtual backgrounds, screen sharing, annotation and camera.

Auditory Attacks: Including but not limited to, obscenities, hate speech and threats of violence.

Chat attacks: This includes the written equivalent of Group 2, but also could includes the usage of Zoom Chat's File transfer capability for distributing images, videos and executable files.

There are generally 2 types of Zoom Bombers

    Berserkers: Begins the attack immediately upon entering a meeting and continues until the meeting is stopped by the host or until they are removed from the meeting. Please note, because they were able to get into the                 meeting once, they will most likely attempt to do so again as quickly as possible.

    Ghosts: Attempts to portray themselves as an invited attendee of the meeting (commonly without a camera being shared). They will commonly change their displayed name to be the same as other participants or to be blank.         These attackers are normally more disruptive after the meeting has started going and they operate in short actions and then try to 'hide.'
