As many turn to video-teleconferencing (VTC) amidst the COVID-19 crisis, reports of VTC hijacking have emerged nationwide.
The US Federal Bureau of Investigation (FBI) has warned the public of VTC hijackers (also known as Zoom-bombing), whereby hijackers join Zoom video conferences for malicious purposes.
In turn the FBI “has received multiple reports of conferences being disrupted by pornographic and/or hate images and threatening language,” read the warning.
According to the warning, two schools in Massachusetts, within the FBI Boston Division’s area of responsibility (AOR) have reported two incidents involving Zoom-bombing.
In late March 2020, a Massachusetts-based high school reported that whilst a teacher was conducting an online class using Zoom, an unknown individual dialed into the conference, yelled profanity and then disclosed the teacher’s home address.
A second Massachusetts-based school reported a Zoom meeting being accessed by an unknown individual. The hijacker was visible on the video camera and had been displaying swastika tattoos.
“As individuals continue the transition to online lessons and meetings, the FBI recommends exercising due diligence and caution in your cybersecurity efforts.”
The FBI has advised users to:
- Do not make meetings or classrooms public.
- Do not Zoom conference links on public social media.
- Manage screen sharing options.
- Ensure users keep their Zoom clients up to date.
- Ensure that the organization’s telework policy or guide addresses requirements for physical and information security.
