To keep yourself safe from such malware, make sure that you only download apps from trustworthy sources. macOS malware used run-only AppleScripts to avoid detection for five years The macOS.OSAMiner has been active since 2015, primarily infecting users in Asia. macOS Malware Used Run-Only AppleScripts to Avoid Detection for Five Years ZDNet Catalin Cimpanu. 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.

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. 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.

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.

Layer 2: Virtualization awareness and anti-emulation To avoid analysis by security researchers, the actors next try to avoid executing their code in a virtual environment. The actors have taken this step to escape common zero-day traps. These “run-only” AppleScripts made it easier for OSAMiner to avoid detection over the years. Focus on a few activities that the CSOC practices well and avoid the ones it. It is well known that most honeypots are named User and Host to attract zero-day malware. 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.
