Xproduct Remediator is available on Macs running macOS Monterey, macOS Big Sur, and macOS Catalina, but it is not available on Macs running older versions of macOS. Apple's new solution is more aggressive and offers more protection.
XProtect Remediator more frequently looks for malware and fixes it if malware is detected.Īpple previously used the Malware Removal Tool (MRT) and XProtect, but XProtect was limited to checking apps and code against a list of known malware and MRT ran infrequently.
Specifically, at around the time that macOS 12.3 Monterey was launched, Apple quietly introduced a new XProtect Remediator tool for its XProtect service that checks for malware in the background. Malware detection on the Mac is now "fully pre-emptive" and as active as "many commercial anti-malware products." "In the last six months, macOS malware protection has changed more than it did over the previous seven years," writes Oakley in a blog post published this week. Malware authors have frequently found and exploited weaknesses, such as using obscure file formats or large file sizes that the sandbox can’t process, leaving Mac users at risk of infection.Apple has made notable updates to macOS malware tools over the course of the last six months, according to updates tracked by Howard Oakley at Eclectic Lighting Company (via Ars Technica). While sandboxing adds another layer of security for Macs, not even the App Store nor sandboxed apps are 100% safe, as highlighted by the attack on the Chinese version of the App Store by the XCodeGhost Virus. XProtect defends Macs against various types of malware, by scanning downloaded files for signs of infection, but it needs to be regularly updated to recognize new or emerging threats - and it won’t help you if you unwittingly land on an infected or unsafe website.Ī digital certificate is always seen as proof of a file’s security and a surefire sign that the file contains no malicious code, but cybercriminals can still plant malicious code at the file completion stage, exploit security gaps to sign their malicious files with valid digital certificates, and more. The macOS, or Mac OS X system, has existed for 40 years in various forms - it’s robust, and because of its regular updates, malware developers find it hard to keep up with the changes and write viruses that will successfully infect the Mac operating system.Īpple's basic malware detection is built directly into its Mac OS X operating system.
