How do I remediate CVE-2019-13450?Malware Removal Osx
Below are three options you can look through.

Install the new version of Zoom zoom.us/support/download

Tuesday, July 9
Zoom issued an update to our Mac app with the following: Removed the local web server via a prompted update Allowed users to manually uninstall Zoom. This new option to the Zoom menu bar allowed users to manually uninstall the Zoom client, including the local web server. A new menu option says, “Uninstall Zoom.” By clicking that button, Zoom’s app and web server are removed from the user’s device along with the user’s saved settings
Wednesday, July 10
Apple issued an update to ensure that the Zoom web server is removed from all Macs, even if the user did not update their Zoom app or deleted it before we issued our July 9 patch. Zoom worked with Apple to test this update, which requires no user interaction.
Weekend of July 13
We have a planned release for the weekend of July 13 that will address video on by default. With this release, first-time users who select “Always turn off my video” will automatically have their video preference saved. 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.) Option #2 Apple MRT – Malware Removal Tool
Apple in a very quick move released MRTConfigDat 1.45 at 5PM CST yesterday. According to TechCrunch
The Cupertino, Calif.-based tech giant told TechCrunch that the update — now released — removes the hidden web server, which Zoom quietly installed on users’ Macs when they installed the app. TechCrunch
Apple said the update does not require any user interaction and is deployed automatically. Apple’s Malware Removal Tool will update on all 10.11, 10.12, 10.13 & 10.14 within 24 Hours
As long as you have sofwareupdate set to Automatically Check for Updates, Download New updates in the background & Install System Data Files and Security Updates. NOTE: 10.11 does not have the include-config-data option so you have to run
sudo softwareupdate -ia -background
I need the update now!
Got you covered! You can use softwareupdate to manually install MRTConfigData 1.45. You can run this to list all available Xprotect Updates.
To install the update you can run
I am not sure yet if just installing the new update actually activates and runs MRT or not. This command works great because it ONLY installs the called out update. If you use
softwareupdate -l --include-config-data it will install ALL softwareupdates including combo and Safari ETC.
Verify that you have 1.45

To force MRT to update run
NOTE: If you are trying to run MRT.app remotely over ssh or by using an MDM, it needs to run as the logged in user at least in 10.14. In 10.12 and 10.13 MRT seems to run fine no matter the user. You can use the 2 lines of code below to get the logged in user then run the command as the user. The error you will get in 10.14 will say failedToReceiveProfileList.
Manual Command that you can run if you are logged in as the user.
Hat Tip to AndyInCali on MacAdmins Slack for the MRT -a !!!
Option #3 Manual Removal + Scripts and Links
Rich Trouton wrote a great script to manually remove zoom’s WebServer.
NOTE: Keep in mind trashing the app will NOT remove the ~/.zoomus Web Server. You will either need to kill the process and then overwrite the file like in Rich’s Script below or wait for MRT or install the new version which removes the Web Server.

Adware is an unwelcome intrusion in many browsers. It attempts to trick or force you into clicking through to a website you weren't planning on visiting, to generate revenue for the company that produced it. Some versions of ad software also contain hidden viruses, posing a serious risk to your Mac and data it contains.
Fortunately, there are ways to remove this rogue software manually via your browser and your system files, and with a cleaner tool like CleanMyMac X. We’ll take you through each of these methods to help you get rid adware on your Mac for good.
The symptoms of an adware infection
Take a look at these symptoms to see if any are familiar:
If you’ve noticed any of things happening when browsing the internet on your Mac you’re almost certainly dealing with adware. In which case, you need to take action.
This is how adware actually looks like
This string of code is an example of adware program on Mac. As you can see in the third line, it 'loads offers' for the user which to you look like intrusive banners and pop-ups.
How to remove adware from your browser
To remove adware from your Mac you need to change your browser preferences and dig into your system files to find and remove the culprit.
Let’s start with the browser. How to stop adware in your browser:
1. Block all pop-ups
The first thing you should do to curb the onslaught of nuisance ads is close all pop-ups. DO NOT DO THIS BY CLICKING ON ANY BUTTON IN A POP-UP. Instead, click on the X in the top left of the window.
If the pop-up refuses to close, press Command+Option+Escape to open the Force Quit window. Select your browser from the list and click Force Quit. Hold down Shift when restarting your browser to stop any previously opened windows from reappearing.
Next, in the Safari Preferences click on the Security icon and select Block pop-up windows.
If you’re a Chrome user, follow these instructions to block pop-ups:
2. Disable unrecognized extensions
Extensions are an important part of the browsing experience but you shouldn’t have anything that you don’t recognize. If the name of a pop-up isn’t familiar or you don’t know what it does, disable it.
Disabling extensions in Safari
Disabling extensions in Chrome
3. Check homepage and search engine settings
Finally, make sure adware hasn’t changed your browser homepage or search-engine settings.
This can be done in the General tab of the Safari browser settings or in the On Startup and Default Browser sections of the Chrome browser settings.
How to remove adware from your system
Tackling adware in your browser will help to improve your browsing experience but it doesn’t guarantee to completely free you from the virus.
Adware often finds its way onto your system by bundling itself in with legitimate Mac software and is installed at the same time. So you’re going to need to delve into your system files to root out the adware and delete it. You can do this manually or with an application like CleanMyMac X.
Because of the way a manual deletion works (sending files to the Trash), CleanMyMac X is the preferred option. A file placed in the Trash and removed can leave behind associated files that lie deep inside system files, meaning the pesky adware still exists on your Mac. CleanMyMac X, on the other hand, scans your system for any leftover parts and removes them in full.
Remove adware from Mac with CleanMyMac X
CleanMyMac X can detect and remove thousands of threats, including adware, viruses, worms, spyware, and more. With its dedicated Malware Removal tool, you’ll stay safe.
Here’s how it’s done:

Another useful feature of CleanMyMac X is real-time monitoring. It checks your Mac in a background mode and notifies you if any adware app attempts to infiltrate your Mac.
Remove adware from your Mac manually
If you’d prefer to remove potential adware manually before opting for an app like CleanMyMac X, it’s easy to do, albeit a little more time-consuming.
Malware Removal Tool Mac FreeNever engage with adware
Adware seeks to steal your money and your personal details and does so by damaging system performance. If you’re worried that your Mac could be infected, err on the side of caution and follow the instructions in this post to lock down your browser and delete files. If you suspect that adware has installed itself on your system, get CleanMyMac X to ensure you get rid of it for good.
CleanMyMac X is recommended by MacStories and MacWorld Magazine as a top Mac utility. Download it today to keep your Mac safe from harmful adware.
