The coronavirus crisis has made Zoom one of the most widely used video conferencing services in the world, which has not escaped the eye of the beholder. Check Point Research has observed a significant increase in the number of domain names imitating that of Zoom in order to trap users. Fake Zoom apps are also in circulation. So you have to be extremely careful with the links you visit and the software you install.
The way you create your Zoom meeting is also important. In many cases, Zoom login links are simply shared online, accessible to everyone.
Our video call was just attacked by someone who kept sharing pornography + switching between different user accounts so we could not block them. Stay tuned for next steps. And I am sorry to everyone who experienced. We shut down as soon as we could.

According to the FBI, some bad pranksters take advantage of this to connect and pollute the meeting: they utter insults, shout neo-Nazi words or broadcast porn movies thanks to screen sharing.
This is what happened to our American colleague Jessica Lessin, from The Information. In the middle of a meeting, strangers connected and shared pornographic content. The intruders had foreseen things well since they had several accounts to avoid being totally banned from the meeting.
To avoid this kind of surprise, the American agency recommends, among other things, locking access to Zoom sessions with a password and limiting screen sharing to the organizer.
