Unless the maintainer is malicious or has himself been compromised without his knowledge I don't see how this malware can spread.

In this way everything IS similar to a game console - much more than windows where people are sharing. the exact program compiled and packaged by the maintainer.

Most programs are installed through official channels and these channels use signature checks to ensure that the user downloaded a vetted program ie. However, by default people are not downloading and running executables on linux that are obtained from random websites.

If the user has any ability to install and run their own software and that software can access the internet, then this type of thing is inevitable in my view. If it's individual cases of users downloading binary files from sketchy places and running them then I don't see how any OS can possibly prevent this sort of user-land thing without completely locking down the system ie. The real question is how it gets installed. It is limited by whatever the user that installed it can do. My read of the netlab site seems to point to this malware can not escalate privileges. The IOCs are available in the SentinelOne OSAMiner report, here. вЂњIn this case, we have not seen the actor use any of the more powerful features of AppleScript that weвЂ™ve discussed elsewhere, but that is an attack vector that remains wide open and which many defensive tools are not equipped to handle.вЂќ вЂњRun-only AppleScripts are surprisingly rare in the macOS malware world, but both the longevity of and the lack of attention to the macOS.OSAMiner campaign, which has likely been running for at least 5 years, shows exactly how powerful run-only AppleScripts can be for evasion and anti-analysis,вЂќ Stokes concluded in his report yesterday. Stokes and the SentinelOne team hope that by finally cracking the mystery surrounding this campaign and by publishing IOCs, other macOS security software providers would now be able to detect OSAMiner attacks and help protect macOS users. Yesterday, Stokes published the full-chain of this attack, along with indicators of compromise (IOCs) of past and newer OSAMiner campaigns.

Since вЂњrun-onlyвЂќ AppleScript come in a compiled state where the source code isnвЂ™t human-readable, this made analysis harder for security researchers.

The primary reason was that security researchers werenвЂ™t able to retrieve the malwareвЂ™s entire code at the time, which used nested run-only AppleScript files to retrieve its malicious code across different stages.ДЄs users installed the pirated software, the boobytrapped installers would download and run a run-only AppleScript, which would download and run a second run-only AppleScript, and then another final third run-only AppleScript.

SentinelOne said that two Chinese security firms spotted and analyzed older versions of the OSAMiner in AugustВ and September 2018, respectively.Д«ut their reports only scratched the surface of what OSAMiner was capable of, SentinelOne macOS malware researcher Phil Stokes said yesterday. Nested run-only AppleScripts, for the win!Д«ut the cryptominer did not go entirely unnoticed. вЂњFrom what data we have it appears to be mostly targeted at Chineses/Asia-Pacific communities,вЂќ the spokesperson added. вЂњOSAMiner has been active for a long time and has evolved in recent months,вЂќ a SentinelOne spokesperson told ZDNetВ in an email interview on Monday. Named OSAMiner, the malware has been distributed in the wild since at least 2015 disguised in pirated (cracked) games and software such as League of Legends and Microsoft Office for Mac, security firm SentinelOne said in a report published this week.

For more than five years, macOS users have been the targets of a sneaky malware operation that used a clever trick to avoid detection and hijacked the hardware resources of infected users to mine cryptocurrency behind their backs.
