Hi,

I'm using Jamf Pro (10.50.0-t1693149930} and I was wondering if someone can guide me to creating a configuration profile to block or prevent the "InstallDefender" from installing with Office 365. Any other suggestion affective suggestion is welcome.

Thanks in advance.

Hi.

Below is the plist that you need.

Create a new profile, give it a name, add the payload "Application & Custom Settings", copy/paste the plist and use the domain "com.microsoft.office", scope in your targets and save.

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>InstallDefender</key>
<false/>
</dict>
</plist>

After deploying that config profile, I made a smart group of potential SHIM installs of computers enrolled 9.11.23 until the date I noticed the SHIM issue (in my case the 19th).  I assigned a policy to that group that runs the script below, which will uninstall that SHIM and run a custom JAMF event to properly install Defender.

 

#!/bin/bash

#Is Defender Installed
AppCheck=$( if [ ! -e /Applications/Microsoft\\ Defender.app ]; then
echo "Not Installed"
else
echo "App Installed"
fi )

#Check for binary
simCheck=$( command -v mdatp )

# Attempt to confirm full Defender Install
if [ "$AppCheck" == "Not Installed" ]; then
echo "Defender Not Installed"
/usr/local/bin/jamf recon
/usr/local/bin/jamf policy -event ShimFix

elif [ "$AppCheck" == "App Installed" ] && [ "$simCheck" != "/usr/local/bin/mdatp" ]; then
echo "Only Shim Installed"
/bin/rm -fr /Applications/Microsoft\\ Defender.app
/usr/local/bin/jamf recon
/usr/local/bin/jamf policy -event ShimFix
else
echo "Defender fully installed"
fi

Thank you of the suggestion, that worked!

Thank you, Daniel, will definitely keep in this in mind. Fortunately, I only had one mac that shim installed, based on the smart group.
