On April 10, 2020, a pro-Islamic State (ISIS) Rocket.Chat channel shared a link to an article published by the Intercept, reporting that Zoom, a video chat service, is not as secure as it claims to be. According to the article, Zoom does not offer end-to-end encryption for audio and video content, and instead uses transport encryption, which is less secure.[1]
