In other words, Apple may have previously been a fortress on a secluded hill, but by now criminals have learned exactly how to get inside. Another built-in security feature is the App Store, which uses a closed developer network to screen new apps.
Before any new app is made available to download, the App Store requires a pre-checked Apple developer ID, proving that Apple has vetted the developer. This check minimized — but did not eliminate — the risk of hackers sneaking malicious apps through the Apple App Store. Eventually some developers found ways to co-opt those IDs. So, starting in , Apple started notarizing apps themselves before distributing them through the Mac App Store. Starting in , Apple no longer pre-installed Flash and Java on new machines.
Both applications were commonly used in early generation websites, but the applications also required frequent security updates. As a result, users who missed those updates were vulnerable to exploits. As the modern web moved toward HTML5 and away from Flash and Java, those applications were no longer essential, and Apple maintained a little extra security by not including them.
However, users who download Flash and Java on their own Macs are reintroducing this potential attack vector. Another Mac security feature is sandboxing. Instead of complete access to any of your user data, sandboxed apps are permitted to access the minimum amount of data required to perform their functions. Apple has required sandboxing of the apps in their app store since Critics complain that sandboxed apps are harder to develop and run more slowly, but they are less vulnerable to attack.
XProtect is a built-in security feature that checks and verifies downloaded apps against a list of known malware. The important word there is known malware — it does not cover the malicious code being newly developed every day.
All Apple-related drivers and updates should come only from Apple itself, reducing the need to apply updates constantly or the chance that malicious code gets injected into a third-party driver update. But in many cases, you can get rid of the intruder without too much trouble, and your device will be back to normal in no time.
