Zoom Video Communications has seen a huge surge in attacks recently due to the demand in remote work and online meeting sessions. Besides worrying about privacy data sharing with certain companies such as Facebook, zoom bombings classrooms, and malware injection, researchers have uncovered 2 new zero day exploits on Mac OS that could give hackers privileged root access. This would allow them to access the user’s microphone and camera. As of Thursday, the two vulnerabilites have been patched, and it’s important to keep with your systems application updates and turn them to automatic.
Other security measures to know when using Zoom is to not post the links publicly, and to not click on any links within Zoom chat meetings. Hosts could also disabled comments in the chatbox, as well as lock new participants from joining once the session is underway. Kicking out selected participants, as well as have a holding room before new participants could join will prevent zoom bombings. Of course, it may be difficult to manage if the class size is too large to keep track of incoming and outgoing students.
