This is clearly Zoom's moment in the spotlight, as the public has embraced the videoconferencing provider's service during the coronavirus lockdown. However, security woes, privacy controversies, and trolling incidents have marred the company's star turn.

The big picture: When Zoom usage soared as Americans started working and studying from home, some worried whether it could handle the load. It did, but other problems cropped up as millions of consumers started using what had been an unsung piece of business software.

Driving the news: Over the past week, researchers have reported a variety of security flaws in Zoom.

Yes, but: Most software is insecure to some degree, and those flaws aren't detected unless usage becomes widespread enough to turn the program into a valuable target. Zoom is now in that unenviable position.

Previously, Zoom came under fire for the way its iOS app shared data with Facebook.

Meanwhile, users of Zoom holding classes and public meetings have found themselves targeted by "zoombombing" hecklers, who are interrupting conferences to introduce hate speech or porn.

Flashback: Last summer, Zoom incurred Apple's wrath because of the way its app installed a secret web server on Macs to save its users a click in the launch process.

Our thought bubble: The same design choices and default settings that made Zoom so easy to install and use are the ones that make it vulnerable. The level of trust that users within a large company assume as they work together breaks down among more heterogeneous groups in public environments.

The bottom line: Zoom's stock has soared recently thanks to its surge in usage, but that ride could turn bumpy.

Biden freezes U.S. arms deals with Saudi Arabia and UAE

The Biden administration has put on hold two big arms deals with Saudi Arabia and the United Arab Emirates which were approved in the final weeks of the Trump administration, a State Department official tells Axios.

Why it matters: The sales of F-35 jets and attack drones to the UAE and a large supply of munitions to Saudi Arabia will be paused pending a review. That signals a major policy shift from the Trump era, and may herald sharp tensions with both Gulf countries.

Robert Downey Jr. launches VC funds to help save the planet

Robert Downey Jr. on Wednesday announced the launch of two venture capital funds focused on startups in the sustainability sector, the latest evolution of a project he launched two years ago called Footprint Coalition.

Between the lines: This is a bit of life imitating art, as Downey Jr. spent 11 films portraying a character who sought to save the planet (or, in some cases, the universe).

The Department of Homeland Security on Wednesday issued an advisory warning of a "heightened threat environment" in the U.S. because of "ideologically-motivated violent extremists."

Why it matters: DHS believes the threat of violence will persist for "weeks" following President Biden's inauguration. The extremists include those who opposed the presidential transition, people spurred by "grievances fueled by false narratives" and "anger over COVID-19 restrictions ... and police use of force[.]"
