It is disguised in pirated (cracked) games and software like League of Legends and Microsoft Office for Mac. According to SentinelOne, a security firm, which published a report this week. OSAMiner has been active for a while and has evolved in recent times, according to a SentinelOne spokesperson. Not too invisibleįrom the data collected, it seems that it attacked people in Chinese and Asian Pacific communities mostly. However, the crypto miner did not completely avoid detection. Back in 2018 August and September, two Chinese security firms analyzed an older version of the Malware.

However, the reports written after this were not very detailed and did not capture the full extent of OSAMiner’s capabilities. The reason was that the researchers were unable to retrieve the malware’s full code. #Macos malware years runonly to detection full

It used nested run-only AppleScript files to retrieve its malicious code across different stages at the time. When the users installed their pirated software, the disguised installers would download and run a run-only AppleScript. It would then download and run a second run-only AppleScript and then run another third/final one.īecause the run-only AppleScript is received in a compiled state (the source code is not readable by humans), security researchers’ analysis was not easy.

#Macos malware years runonly to detection code Phil Stokes, a macOS malware researcher at SentinelOne, published the attack’s full-chain with past and present OSAMiner campaigns and IOCs (Indicators of Compromise). The hope for this team of researchers is that they can crack the mystery around this clever malware.As Mac malware increases in prevalence, testing security software that supplements OS X internal security gets more important and more difficult.Īnti-malware testing on the Windows platform remains highly controversial, even after almost two decades of regular and frequent testing using millions of malware samples. While Macs have fewer threats there are fewer prior tests on which to base test methodology, so establishing sound mainstream testing is trickier than your might think, not least because so few people have experience of it. #Macos malware years runonly to detection softwareīut as both Macs and Mac malware increase in prevalence, the importance of testing software that’s intended to supplement the internal security of OS X increases, too. That’s what it says in the abstract for our recent Virus Bulletin paper, but that’s because it happens to be what we think. Of course, we encourage you to read the paper – Mac Hacking: the Way to Better Testing? But this is the first article in a blog series, based on the presentation rather than directly on the paper, giving a more concise summary of our views. We’re not about to give an airing to the usual fanboi ‘Windoze bad, OS X impregnable’’ stuff.
