New Malware Maker Got Past Apple Security
Apple has been historically very good at keeping malware out of their app store, and they're constantly improving their security protocols on that front. In fact, since February of this year (2020), all Mac software distributed outside of its Mac App Store must be notarized by Apple. The developers must demonstrate that their products are capable of running on macOS Catalina and above.
Any software developed for macOS goes through a multi-stage approval process, with the first step being automated. It is designed to scan software for code-signing issues and malicious components. Assuming the submitted code passes through this security checkpoint, the apps are put on the macOS Gatekeeper list. The list signifies that they've been scanned and it has been determined that they don't pose a security risk.
