This process is executed quickly and is an essential feature of an antivirus software, but it is also easy for cybercriminals to evade. Specific detection works by scanning a file for a specific set of characteristics and checking these characteristics against a known list of malware.
This is what most people think of when they think about how an antivirus works. The most basic detection process is known as specific detection. Most modern antivirus programs feature multiple scanning detection processes. 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.Whenever you download or launch a file, an antivirus program scans the file for malware. 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.
