The Zoom video meeting service has found several security flaws in its system. The company asks its users to update their applications to the latest version, both on mobile and desktop, to avoid cyber attacks.

The other two bugs reported by the company, in this case considered “medium” in severity, mean that “a malicious actor can join a meeting that he is authorized to enter without appearing to the other participants.”

The holes have been found by Zoom’s own Offensive Security team. These types of professionals are dedicated to trying to hack their own applications in search of failures.

To do this, access the download center of Zoom, and download and install the latest version available”, they recommend to users. Incibe has also classified its alert as a “high” priority.
