Apple has just released an update to XProtect, bringing it to version 5372, for all Macs. As usual it doesn’t release information about what security issues this update might address.
This is another major update, which amends a huge number of Yara rules going back many years, adds 5 new rules for MACOS.ANGRYORB.GOFU, MACOS.BOATLOAD.CLPIA, MACOS.BOATLOAD.CLHTA, MACOS.BRUSQUEBARNACLE.VAA and MACOS.BRUSQUEBARNACLE.DOA, and removes 10 rules for MACOS.f5d33c9, MACOS.1373c52, MACOS.3ea93d1, MACOS.de444f2, MACOS.b70290c, MACOS.22d71e9, OSX.XAgent.A, OSX.iKitten.A, OSX.Hmining.A and MACOS.44db411.
Changes in the Osascript rules in XPScripts.yr include adding one new rule for MACOS.OSASCRIPT.REETCHRE, and removing 3 rules for MACOS.OSASCRIPT.DUVAST, MACOS.OSASCRIPT.DUCUHA and MACOS.OSASCRIPT.DUSTCO.
In older versions of macOS 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_15-5372
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 5372 but your Mac still reports an older version is installed, you should be able to force the update using
sudo xprotect update
Those should now work correctly in Sequoia.
