Neither behavior represents a critical vulnerability, but they do suggest Zoom developers could do more to lock down the Mac version of their app, particularly for users who may have less awareness of security issues.

But in hearing the outcry from our users in the past 24 hours, we have decided to make the updates to our service.

If the webcam is covered by tape or a sticker, they likely are.

A recently published report on the Zoom conferencing application for Macs underscores why this practice makes sense.

Its not hard to imagine this being a problem for people in their bathrobes or in the middle of a sensitive business conference since a malicious link would give no warning in advance it will open Zoom and broadcast whatever is in view of the camera.

But unless users have properly tweaked their settings in advance, Lietschuhs findings show how miscreants can turn this ease-of-use against unwitting users.

A proof-of-concept exploit is available here, but reader be warned: depending on your Zoom settings, your webcam may soon be transmitting whatever it sees to perfect strangers.

Clicking the link will automatically open Zoom and join a call.

But as mentioned earlier, video is collected only when Zoom is configured to begin conferences with a camera turned on.

Some media reports and social media commentators have said this behavior allows websites to hijack a Mac webcam.

Id argue thats a stretch since (1) its fairly obvious that Zoom is opening and broadcasting whatever the camera sees and (2) its easy to immediately leave the conference or simply turn off the camera.

But user beware: even when this setting is on, sites still can force Macs to open Zoom and join a conference.

Make a feature too hard to use and people will move to a competing product.

Make it too easy and attackers may abuse it to do bad things the developer never imagined.

Instead, the developers left it up to users to decide with no up-front guidance.

By contrast, audio is automatically turned off when joining a Zoom conference.) In other words, Zoom developers made this automatic webcam joining way too easy.

In retrospect, thanks to Leitschuhs post, thats easy to see.

Farley didnt say if Zoom will provide the guidance many users will need to make an informed choice.

This server continues to run even when a Mac user uninstalls Zoom.

Leitschuh showed how this webserver can be abused by people on the same network to force Macs to reinstall the app.

While the webserver is only accessible to devices on the same network, that still exposes people using untrusted networks.

And if hackers were ever to come across a code-execution vulnerability in the webserver, the potential for abuse is even higher.

Farley said Zoom introduced the webserver as a way to work around a change introduced in Safari 12 that requires users confirm with a click each time they want to start the Zoom app prior to joining a meeting.

We are not alone among video-conferencing providers in implementing this solution.

There is no evidence that the behavior Leitschuh reported is found in Zoom for Windows.
