NASHVILLE, Tenn (CLARKSVILLENOW) – As the COVID-19 pandemic continues, more people are using web-based teleconferencing applications for work, school and socializing. Zoom has become particularly popular; however, the Better Business Bureau has warned users of a new trend called “Zoom-Bombing,” in which hijackers access their Zoom Session.

How does Zoom-Bombing’ work?

Zoom allows users to host audio and video conference calls on a public channel which users can join by using a unique session URL or meeting ID. Potential hijackers will attempt to guess these codes until they have gained access to a live feed.

The FBI’s Boston office reported two incidents in March, 2020. In the first incident, a Massachusetts high school teacher was holding class using Zoom when an unknown person(s) entered the session. The hijacker(s) shouted obscenities as well as the teacher’s home address.

Another incident in Massachusetts involved a teacher’s lesson being hijacked, this time with the individual appearing on video and displaying swastika tattoos.

How to avoid video hijacking

The BBB and FBI have shared techniques and strategies users can implement to protect the privacy of their online communications. When using video-conferencing apps such as Zoom:

  • Avoid public meeting when possible. Private conferences and calls require a password to enter and are more secure than public calls.
  • Use a one-time code rather than Personal Meeting ID (PMI) when hosting a public Zoom session with multiple members.
  • Set meetings to require a password.
  • Never share your account’s Personal Meeting ID publicly. This number is directly tied to your account and should only be shared with trusted individuals.
  • Only allow hosts to screen share. Zoom allows users to share what is on their screen with other people in the session. Setting this function to host only prevents hijackers from sharing graphic and/or unwelcome content.
  • Create waiting rooms for public calls. Doing so allows the host to screen and approved users before they enter the general call.
  • Set Meetings to invite only.
  • Limit or disable file transfer. Zoom’s settings allows the host to limit other user’s ability to share files with other people in the call.
  • Keep your applications up to date to ensure the best possible security features.

If you are a victim of ‘Zoom Bombing’ or any other form of teleconference hijacking, complaints can filed with the FBI’s Internet Crime Complaint Center (IC3) here.
