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. MALWARE USED RUNONLY APPLESCRIPTS TO AVOID 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. MALWARE USED RUNONLY APPLESCRIPTS TO AVOID 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). ServiceNow San Diego aims for big productivity boost The hope for this team of researchers is that they can crack the mystery around this clever malware. An anonymous reader quotes a report from ZDNet: 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. When Fred Luddy founded ServiceNow, the goal was to build a platform on which many services and products coul.

AWS organizes GameDay, a world championship for developers MALWARE USED RUNONLY APPLESCRIPTS TO AVOID UPDATE The AWS GameDay is just around the corner.

OSAMiner has been secretly mining cryptocurrency on affected Macs The capabilities are intended to be.How to manage notifications for messages on iPhone MariaDB is acquiring CubeWerx, giving it access to geospatial technology. OSAMiner has been active since 2015, secretly mining cryptocurrency on affected Macs. The malware has also evolved recently and has primarily targeted users in China and Asia-Pacific. When users downloaded the affected apps, an AppleScript would be downloaded which would run a second AppleScript, which would, in turn, download the third AppleScript. SentinelOne noted that run-only AppleScripts are rarely used for macOS malware, but OSAMiner showed that they are incredibly powerful for malicious intents and can be used to remain hidden from detection: These “run-only” AppleScripts made it easier for OSAMiner to avoid detection over the years. Run-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. In this case, we have not seen the actor use any of the more powerful features of AppleScript that we’ve discussed elsewhere, but that is an attack vector that remains wide open and which many defensive tools are not equipped to handle. In the event that other threat actors begin picking up on the utility of leveraging run-only AppleScripts, we hope this research and the tools discussed above will prove to be of use to analysts. Now that OSAMiner has been detected and its complex architecture has been reverse engineered, it will help other researchers in finding any other hidden “run only” AppleScript malware. To keep yourself safe from such malware, make sure that you only download apps from trustworthy sources.
