Checking if Apple’s Zoom remediation update has been installed on your Mac

July 12, 2019 Leave a comment

As part of the Zoom vulnerability issue, further problems have been discovered as security researchers look into the local webserver installed by older versions of the Zoom app for macOS.

Apple has moved quickly and released an update to MRT (Malware Removal Tool) which addresses the issue by removing the local webserver. This update has the following version number:

1.45.1.1562731315

The installer package receipt associated with it is the following:

com.apple.pkg.MRTConfigData_10_14.16U4071

To verify that you have this installed, here’s a one-line command to check for the latest installed MRT installer package:

To verify that com.apple.pkg.MRTConfigData_10_14.16U4071 does install 1.45.1.1562731315, here’s a one-line command to get the version number from the latest installed MRT installer package receipt:

To assist with getting information like this for Gatekeeper, MRT and XProtect, I’ve written a script that pulls the following information for each:

  • Version number
  • Installation date
  • Installer package receipt identifier

To assist with this, I’ve written a couple of scripts to report the last time that Gatekeeper and XProtect have been updated on a particular Mac. For more details, see below the jump.
