The selection will automatically be applied to the user's Zoom client settings and their video will be OFF by default for all future meetings. Returning users can update their video preferences and make video OFF by default at any time through the Zoom client settings," the company added. Zoom made the change after the company's CEO spoke with Leitschuh over a call. You can find more details about the mitigations in the company's updated blog post.
Original Story: Be careful around the video conferencing app Zoom; a feature in the product's Mac client can theoretically let a stranger spy on you via the web camera.

For Zoom users to invite people to a video-conferencing meeting on the app, they need only share a web link. If clicked on, the link will automatically start up the Zoom app—assuming the user has it installed—and begin recording through the Mac's web camera.
The same feature can be exploited to spy on Zoom users, according to security researcher Jonathan Leitschuh, who started investigating the app earlier this year. According to Leitschuh, a hacker could create a meeting and embed a link to it in a website. If a Mac owner then visited that site, the Zoom app would automatically launch and begin recording from the web camera. To demonstrate the threat, Leitschuh created proof-of-concepts showing how the attack can work. Be warned: clicking on the links will jumpstart the Zoom app on a Mac, and pull you into a video meeting populated by strangers.
The attack can also work on Windows-based computers if you've allowed your internet browser to automatically run Zoom meetings. If you've ever checked this box on any browser other than Safari, you are vulnerable as well.

In response, Zoom rolled out a patch designed to prevent a meeting creator from enabling participants' web cameras by default. However, Leitschuh claims the patched version can still let a hacker activate webcams. Despite Leitschuh's warnings, Zoom is downplaying the security concerns.
The company notes the application will pop up over a desktop in the foreground when activated. The reasoning is also why Zoom doesn't consider the problem to be a vulnerability. The app was designed to let users seamlessly join video conference meetings with one click. Once we narrowed down the field, we took multiple pictures and videos with each webcam under controlled conditions so we could compare them directly. We then had seven Wirecutter staffers compare the images and videos from the different cameras, without knowing which was which, and rank their quality from best to worst.
We used that data, our findings from the previous version of this guide, and notes from other professional reviewers to settle on our picks. All of these webcams are automatically detected by Windows 10, macOS, and other modern operating systems; Windows 10 downloads and installs the necessary drivers for you. The Logitech HD Pro Webcam C is the best option for most people who need a stand-alone webcam, thanks to its superb image quality, ease of setup, and helpful but optional software.
Its video—p at 30 frames per second—was crisp and clear in our testing, and the autofocus and auto white balance features worked better than those of any of the other webcams we tested. When comparing pictures taken by the six webcams we examined, our testers consistently ranked the C first, beating out even newer and more expensive models like the Cx and the Logitech Brio.

The C produces sharp, p-resolution video both locally and streamed through services such as Skype, Google Hangouts, and Zoom though many services default to, or max out at, p to save bandwidth. It did just as well as or better than the more expensive Cx and the Brio in these tests.
Like the other webcams we tested, the C works right out of the box on Windows, macOS, and Chrome OS—just connect its USB-A plug to your computer directly or via an adapter and launch your video-recording or video-chat software of choice. If you need more control, you can manually adjust exposure, gain, brightness, contrast, color intensity, white balance, and focus using the Logitech Webcam Controller software for Windows or the Logitech Camera Settings software for Mac.
The C sits on top of your screen: A fold-out foot braces against the back of your laptop or monitor, while a plastic tab sits in front to hold the camera in place. The C is universally loved by reviewers.
The C has the best meta rating on Engadget , and is the top seller on Amazon with a rating of 4. We continue to recommend it based not only on our formal research and testing but also on our extensive experience using it every day. It's never acted weird or given me a hard time about anything. The same apps Logitech Webcam Controller for Windows and Logitech Camera Settings for Mac work with the C if you want manual control over the framing, exposure, brightness, contrast, color intensity, white balance, or focus.
You can still perch the C on top of your screen, on your desk, or on a separate tripod for use. The C can also swivel from side-to-side or tilt up and down, while the C can only tilt, and you can fold up the C when not in use, with the stand protecting the lens if you want to throw it in your laptop bag.
A 60 fps webcam is primarily of interest to people who frequently stream using live video services like Twitch, which can stream p videos at up to 60 fps. For streamers who overlay video of themselves atop 60 fps game footage, having a webcam that can also record at 60 fps makes for a smoother, nicer-looking stream. And the Cx comes with a tripod, which gives streamers more flexibility than the normal Cstyle clip allows. The Windows-only ChromaCam software that the Cx uses for background replacement actually works with any webcam, including the C In our testing, the feature did an okay job distinguishing my torso, head, and hair from the rest of the room as long as the light was good, but it had trouble recognizing or separating my arms and hands from the background, and it sometimes included the back of my chair, too.
The exposure, color, and level of detail captured by the two cameras are similar overall, and most testers still preferred the Cx to the more expensive Logitech Brio. Both the Windows and Mac versions of the Logitech Camera Settings app for the Cx require you to open a separate app like the Windows Camera app or Photo Booth to preview your image as you adjust it.
You may have noticed other people including tech luminaries covering their webcams with tape to protect their privacy. Almost all webcams, including every webcam we tested for this guide, have indicator lights that turn on when the webcam is active. The popularity and longevity of the C mean that there are multiple covers made just for it. In particular, they do not prevent audio recording.
Razer released a new webcam that features a simple, but effective, advantage over our current picks.
The Razer Kiyo adds an adjustable ring light to a Razer webcam lens, ensuring that anyone in front of the Kiyo will be properly lit. We plan to test whether the additional functionality is worth the price soon. They can also use 3D facial recognition to log you in to your computer via Windows Hello some other webcams, including the Logitech Brio we tested, use a simpler IR camera for this , and they support hand- and finger-tracking.
If and when these cameras become smaller and cheaper, they may become compelling alternatives to traditional webcams. We disqualified the Logitech Brio because it costs more than three times as much as the C, and because our testers almost always preferred images and video taken by both the C and C That said, the Brio is the only webcam we tested that can record 4K video—but only on computers with seventh-generation or newer Intel Core processors or modern dedicated graphics cards.
The Brio also has a built-in infrared camera that you can use to log into Windows 10 using your face via Windows Hello, and it has a USB-C port instead of a built-in cable so you can use whatever type and length of USB cable you want.
