You’ve probably heard of the popular video conferencing platform, Zoom. This platform enables its millions of users in various locations to virtually meet face to face. In an effort to enhance user experience and work around changes in Safari 12, Zoom installed a web server that allows users to enjoy one-click-to-join meetings. Unfortunately, a security researcher recently disclosed that this product feature acts as a flaw that could allow cybercriminals to activate a Mac user’s webcam without their permission.
One sign of OS X’s overall security savvy is that it has its own built-in firewall, which is pretty good. But there are many other firewall add-on apps for the Mac, including Brian Hill’s. Protect your Mac from malware. MacOS has many features that help protect your Mac and your personal information from malicious software, or malware.One common way malware is distributed is by embedding it in a harmless-looking app.
How exactly does this vulnerability work? Cybercriminals are able to exploit a feature that allows users to send a meeting link directly to a recipient. When the recipient clicks on the link, they are automatically launched into the video conferencing software. If the user has previously installed the Zoom app onto their Mac and hasn’t turned off their camera for meetings, Zoom will auto-join the user to a conference call with the camera on. With this flaw, an attacker can send a victim a meeting link via email message or web server, allowing them to look into a victim’s room, office, or wherever their camera is pointing. It’s important to note that even if a user has deleted the Zoom app from their device, the Zoom web server remains, making the device susceptible to this vulnerability.
While the thought of someone unknowingly accessing a user’s Mac camera is creepy, this vulnerability could also result in a Denial of Service (DoS) attack by overwhelming a user’s device with join requests. And even though this patch has been successfully patched by Zoom, it’s important for users to realize that this update is not enforced by the platform. So, how can Zoom users avoid getting sucked into a potentially malicious call? Check out these security tips to stay secure on conference calls:
- Adjust your Zoom settings. Users can disable the setting that allows Zoom to turn your camera on when joining a meeting. This will prevent a hacker from accessing your camera if you are sent a suspicious meeting link.
- Update, update, update. Be sure to manually install the latest Zoom update to prevent DoS or other potential attacks. Additionally, Zoom will introduce an update in July that allows users to apply video preferences from their first call to all future calls. This will ensure that if a user joins their first meeting without video, this setting will remain consistent for all other calls.

Apple T2 chip.
The next generation of security.
The Apple T2 Security Chip — included with many newer Mac models — keeps your Mac safer than ever. The Secure Enclave coprocessor in the Apple T2 chip provides the foundation for Touch ID, secure boot, and encrypted storage capabilities. Touch ID gives you a seamless way to use your fingerprint to unlock your Mac, fill passwords in Safari, and make purchases with Apple Pay. Secure boot helps ensure that you are running trusted operating system software from Apple, while the Apple T2 chip automatically encrypts the data on your Mac. So you can be confident knowing that security has been designed right into the architecture of your Mac, from the ground up.
Apple helps you keep your Mac secure with software updates.
The best way to keep your Mac secure is to run the latest software. When new updates are available, macOS sends you a notification — or you can opt in to have updates installed automatically when your Mac is not in use. macOS checks for new updates every day, so it’s easy to always have the latest and safest version.
Protection starts at the core.
The technically sophisticated runtime protections in macOS work at the very core of your Mac to keep your system safe from malware. This starts with state-of-the-art antivirus software built in to block and remove malware. Technologies like XD (execute disable), ASLR (address space layout randomization), and SIP (system integrity protection) make it difficult for malware to do harm, and they ensure that processes with root permission cannot change critical system files.
Download apps safely from the Mac App Store. And the internet.
Now apps from both the App Store and the internet can be installed worry-free. App Review makes sure each app in the App Store is reviewed before it’s accepted. Gatekeeper on your Mac ensures that all apps from the internet have already been checked by Apple for known malicious code — before you run them the first time. If there’s ever a problem with an app, Apple can quickly stop new installations and even block the app from launching again.
Stay in control of what data apps can access.
Apps need your permission to access files in your Documents, Downloads, and Desktop folders as well as in iCloud Drive and external volumes. And you’ll be prompted before any app can access the camera or mic, capture keyboard activity, or take a photo or video of your screen.
FileVault 2 encrypts your data.

Designed to protect your privacy.
The most secure browser for your Mac is the one that comes with your Mac. Built-in privacy features in Safari, like Intelligent Tracking Prevention, help keep your browsing your business. Automatic strong passwords make it easy to create and use unique passwords for all the sites you visit. And iCloud Keychain syncs those passwords securely across all your devices, so you don’t have to remember them. You can also easily find and upgrade any weak passwords you’ve previously used (and reused and reused and reused).

Find your missing Mac with Find My.
The Find My app combines Find My iPhone and Find My Friends into a single, easy-to-use app on Mac, iPad, and iPhone. Find My can help you locate a missing Mac — even if it’s offline or sleeping — by sending out Bluetooth signals that can be detected by nearby Apple devices. These devices then relay the detected location of your Mac to iCloud so you can locate it in the Find My app. It’s all anonymous and encrypted end-to-end so no one — including Apple — knows the identity of any reporting device or the location of your Mac. And it all happens silently using tiny bits of data that piggyback on existing network traffic. So there’s no need to worry about your battery life, your data usage, or your privacy being compromised.
