Apple has released its regular weekly update to XProtect for all versions of macOS, bringing it to version 5347. As usual it doesn’t release information about what security issues this update might address.

This version adds three new Yara rules for MACOS.BONZAI.COBUCH, MACOS.SOMA.STTX and MACOS.SOMA.ENCOA. The Osascript rules in XPScripts.yr also gain three new rules, for MACOS.OSASCRIPT.ODPAIN, MACOS.OSASCRIPT.ANMA and MACOS.OSASCRIPT.REOB, while those for MACOS.OSASCRIPT.SYPR and MACOS.OSASCRIPT.BOMSPAA are amended, and MACOS.OSASCRIPT.TAPEPA is removed.

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 Tahoe 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_15-5347

Sequoia and Tahoe systems only
