Have you used the popular Zoom platform for videoconferencing or screen sharing? We primarily don't, but recent security flaws uncovered on Zoom lead us to suggest that you uninstall it (instructions courtesy of BuzzFeed).

What to Do About It

Go to Zoom settings > Video, and under Meetings, enable “Turn off my video when joining a meeting.”

OR

Get rid of the Zoom desktop app entirely. If you want to get ahead of Zoom’s patch, which the company said will be released by midnight tonight, first you need to shut down the web server. Open the application called Terminal. Copy and paste this text: lsof -i :19421. Press enter. You’ll get a string of mumbo jumbo. Underneath the text “PID,” copy the string of numbers. Then type “kill -9” (without the quotes), add a space after -9, and paste the PID string of numbers. Press enter. The server has been killed.

Drag the Zoom app, along with a folder titled “.zoomus,” to the trash can. Then hover over the trash can, and press CONTROL and click your mouse simultaneously. Empty the trash can. Boom.
