I’m not even mentioning the drama when it comes to supporting the different compression formats, signing applications, and 64-bit requirements.Īlmost 2 years later, I proudly present ApplePi-Baker v2. This came with quite a few challenges, especially since Apple increased security for macOS, not allowing me to do certain things straight from my program (see also SMJobBless: Elevated Privileges in Lazarus Pascal). Besides that, having to enter your “ sudo” password each time was a pain as well, and came with the occasional problems for a small group of users, so that had to go as well.Ībout 2 years ago I decided to rebuild ApplePi-Baker from scratch, no longer using any of the command-line tools. Over time, the use of command-line tools came with some problems thanks Apple for changing command-line tool output with every new version of macOS. This way, ApplePi-Baker became my personal frontend for command-line tools like “ dd“, “ diskutil“, “ mount” etc. Late 2013, I created ApplePi-Baker for my own use – I just got tired of looking up the proper command-line statements. Users do not just use ApplePi-Baker for this purpose anymore – I have seen users use it for backup and restore of pretty much anything not Raspberry Pi related. ApplePi-Baker has become well known amongst Raspberry Pi users, with a Mac running macOS, to backup and restore SD-cards. The IOCs are available in the SentinelOne OSAMiner report, here. "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," 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 "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. ![]()
