In a memo to employees obtained by Reuters and posted on Wednesday, SpaceX officials said Zoom suffers from "significant privacy and security concerns" that make it an unsuitable choice for the space-focused company.

On Wednesday, however, security researcher Patrick Wardle said that he had discovered two security holes in Zoom that would allow hackers with local access to a user's machine to control the computer, as well as its microphone and webcam. .

A transparency report will help users see security problems and a revised bug bounty program will boost Zoom's ability to spot and squash security holes.

With 200 million users, managing Zoom and improving security in such a short time won't be easy.
