Zoom: Rush of WFH Users Exposed Security, Privacy Flaws We Plan to Fix

Growing from 10 million to 200 million users in a matter of months caught Zoom off guard, so it's temporarily freezing development on new features to focus on security and privacy issues.

Amid the coronavirus pandemic, Zoom has seen daily user counts for the video conferencing service skyrocket to 200 million, up from 10 million in December. 

Of course, popularity brings scrutiny. On Wednesday, Zoom CEO Eric Yuan pointed to the company’s insane growth as he apologized for falling short on expectations for privacy and security.

“We did not design the product with the foresight that, in a matter of weeks, every person in the world would suddenly be working, studying, and socializing from home,” he wrote in a blog post. “We now have a much broader set of users who are utilizing our product in a myriad of unexpected ways, presenting us with challenges we did not anticipate when the platform was conceived.”

In response, Zoom is temporarily freezing development on new features and will instead devote its engineering manpower to addressing security and privacy issues. The company is also killing off the creepy “attendee attention tracker” feature, which allowed Zoom meeting hosts to monitor the computers of everyone in the session. In addition, Zoom has patched three vulnerabilities in the app that security researchers uncovered this week. 

“Over the next 90 days, we are committed to dedicating the resources needed to better identify, address, and fix issues proactively,” Yuan added. “We are also committed to being transparent throughout this process.” 


An example of a Zoom video meeting

As part of this process, Zoom is bringing in third-party experts and consumers to help it review the video-conferencing service for unknown security problems. It’s also going to start publishing transparency reports on when Zoom receives requests from government authorities to hand over user information. 

Finally, the company is trying to clear the confusion around its claim that Zoom offers end-to-end encryption. The company does, but only when all the connecting devices, such as laptops and smartphones, are joining the meeting via the installed Zoom app.

“In this scenario, where all participants are using the Zoom app, no user content is available to Zoom’s servers or employees at any point during the transmission process,” the company wrote in a separate blog post. However, if users are connecting to the meeting via a phone line, they're out of luck. 

Zoom also notes it does hold on to the encryption keys for the end-to-end process. That said, the company says it's never built a mechanism to decrypt live meetings to help law enforcement intercept messages or videos. “Nor do we have means to insert our employees or others into meetings without being reflected in the participant list,” the blog post adds. 

We’ll have to wait and see whether the newly announced efforts resolve any of the problems facing the video-conferencing service. But the product’s sudden popularity has also made it a target for pranksters and racists. For days now, they’ve been infiltrating unsecured Zoom meetings to harass people, which has prompted the FBI to issue a warning about “Zoom-bombing” attacks. Zoom also published a blog post with tips on securing your video sessions from unwanted intruders; PCMag has a guide, too.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
