![]() ![]() Viruses and other malware: Emails are often used to lure unsuspecting people. Since "run-only" AppleScript come in a compiled state where the source code isn't human-readable, this made analysis harder for security researchers. Firewalls Dont Stop Dragons: A Step-by-Step Guide to Computer Security and. As 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. 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. 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. A cryptocurrency mining campaign targeting macOS is using malware that has evolved into a complex variant giving researchers a lot of trouble analyzing it. The miner setup script also uses the built-in caffeinate tool to prevent the Mac sleeping and also does some evasion checks. Hopefully, analysts can use the research done in this campaign to help prevent future run-only. But their reports only scratched the surface of what OSAMiner was capable of, SentinelOne macOS malware researcher Phil Stokes said yesterday. Case-in-point being the macOS.OSAMiner campaign, which took at least five years to crack open. party developers such as anti-virus vendors on Mac OS X, an approach also. SentinelOne said that two Chinese security firms spotted and analyzed older versions of the OSAMiner in August and September 2018, respectively. Forty-five years of research have explored these and other concepts in great. But the cryptominer did not go entirely unnoticed. MacOS users have been the target of a sneaky malware operation for more than five years that used a clever trick to avoid detection and hijack infected. 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. 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.
