When using platforms like Zoom, the FBI recommends exercising due diligence and caution in your cybersecurity efforts. Investigators say to follow these steps to mitigate teleconference hijacking threats:
• Do not make meetings or classrooms public. In Zoom, there are two options to make a meeting private: require a meeting password or use the waiting room feature and control the admittance of guests.
• Do not share a link to a teleconference or classroom on an unrestricted publicly available social media post. Provide the link directly to specific people.
• Manage screen sharing options. In Zoom, change screen sharing to, “Host Only.”
• Ensure users are using the updated version of remote access/meeting applications. In January 2020, Zoom updated its software. In the security update, the teleconference software provider added passwords by default for meetings and disabled the ability to randomly scan for meetings to join.
• Lastly, ensure that your organization’s telework policy or guide addresses requirements for physical and information security.
If you were a victim of a teleconference hijacking or any cyber-crime, report it to the FBI’s Internet Crime Complaint Center at ic3.gov.
Additionally, if you receive a specific threat during a teleconference, please report it at tips.fbi.gov or call the FBI Boston Division at (857) 386-2000.
