We work collaboratively with clients and their service providers. We are not an IT service provider or IT consultancy although we possess a comparable level of technical expertise found within the technical service providers, as well as leading industry qualifications in Cyber Security, IT, HR and Finance. Our experience spans British Intelligence, UK Central Government, FTSE100 and global financial services as well as Big-4 Consulting and Regulation, including the thematic review that led to the GFSC Cyber Security Rules. We firmly believe that Cyber and Information Security requires aligned and proportionate controls across people, operations and technology. OSAMiner typically spreads via pirated copies of games and software, League of Legends and Microsoft Office for macOS being among the more popular examples. used for malicious purposes, so at first, the book covers universal basic. The organisation’s security must be governed by a Board that has a sound understanding of the fundamentals of Cyber Security.
The malware has been researched in the past 1, 2 but the run-only AppleScript file hindered full analysis, limiting it to observing the behavior of the sample. #Malware used runonly applescripts avoid detection full# The VM and sandbox detection techniques that malware authors use to avoid. #Malware used runonly applescripts avoid detection windows 10#.

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 “run-only” AppleScript come in a compiled state where the source code isn’t human-readable, this made analysis harder for security researchers. The primary reason was that security researchers weren’t able to retrieve the malware’s entire code at the time, which used nested run-only AppleScript files to retrieve its malicious code across different stages.Īs 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 August and September 2018, respectively.īut 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!īut the cryptominer did not go entirely unnoticed. “From what data we have it appears to be mostly targeted at Chineses/Asia-Pacific communities,” the spokesperson added. “OSAMiner has been active for a long time and has evolved in recent months,” a SentinelOne spokesperson told ZDNet 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.
