There’s an old saying among American investors: I’m betting that these two don’t either, although Apple has neutralized it. The last time these two were updated, you mentioned that neither addresses the “Silver Sparrow” malware. I am grateful to Phil Stokes at Sentinel Labs for decoding of the obfuscated malware names here. I maintain lists of the current versions of security data files for Big Sur on this page, Catalina on this page, Mojave on this page, High Sierra on this page, Sierra on this page, and El Capitan on this page. I have updated the reference pages here which are accessed directly from LockRattler 4.2 and later using its Check blog button. If your Mac has not yet installed this update, you can force an update using SilentKnight, LockRattler, or at the command line.
You can check whether this update has been installed by opening System Information via About This Mac, and selecting the Installations item under Software.Ī full listing of security data file versions is given by SilentKnight, LockRattler and SystHist for El Capitan, Sierra, High Sierra, Mojave, Catalina and Big Sur, available from their product page. Update: Phil Stokes has corrected my original list, and identified these three additions as being AdLoad (MACOS.2afe6bd), Bundlore (MACOS.b5bd028), and Genieo, MaxOfferDeal (MACOS.d98ded3). Apple has just pushed two updates, to the data files used by XProtect, bringing its version number to 2141 dated 4 March 2021, and to its malware removal tool MRT, bringing it to version 1.75, also dated 4 March 2021.Īpple doesn’t release information about what these updates add or change, and now obfuscates the identities of malware detected by XProtect using internal code names.Ĭhanges found in the XProtect Yara definitions include removal of the signature for MACOS.7ef4bab (AdLoad variants, which had only been added in version 2140) and addition of those for MACOS.2afe6bd, MACOS.b5bd028 and MACOS.d98ded3.
