Apple has just released an update to XProtect for all versions of macOS, bringing it to version 5352. As usual it doesn’t release information about what security issues this update might address.

This version adds two new Yara rules for MACOS.BOATLOAD.REWA and MACOS.BOATLOAD.REFU, unusually removes those for MACOS.DUBROBBER.D and MACOS.DUBROBBER.E, and amends that for MACOS.SOMA.D. There are no changes in the Osascript rules in XPScripts.yr this time.

You can check whether this update has been installed by opening System Information via About This Mac, and selecting the Installations item under Software.

A full listing of security data file versions is given by SilentKnight and SystHist for El Capitan to Golden Gate available from their product page. If your Mac hasn’t yet installed this update, you can force it using SilentKnight or at the command line.

If you want to install this as a named update in SilentKnight, its label is XProtectPlistConfigData_10_15-5352

Sequoia, Tahoe and Golden Gate systems only

This update has already been released for Sequoia and later via iCloud. If you want to check it manually, use the Terminal command
sudo xprotect check
then enter your admin password. If that returns version 5352 but your Mac still reports an older version is installed, you should be able to force the update using
sudo xprotect update

I’m very grateful to John for so promptly drawing my attention to this update.
