Next, we search for instances of “parallels”. Then we call the xxd utility from vi’s command line: In our case, we are using an isolated Parallels Virtual Machine for this lab, so some light binary patching should take care of the VM detection.įirst, we copy the binary off the DMG to local disk, and then open the binary in the vi editor: Since it is always wise to reverse macOS malware in an isolated test environment, we had to alter the sample slightly in order to beat its built-in anti-analysis detection routine. The ARA0848.app’s Mach-O executable contains logic to detect execution in a Virtual Machine environment as a means to thwart macOS malware researchers using any one of Parallels, VMWare or VirtualBox virtualization software:

The Bash script, Install Çağlayan, contains the logic for executing the malicious application bundle in the hidden. The trojan installer’s MacOS folder contains two executable files and a directory. In their report, Amnesty provided the following hash for this sample on VirusTotal which we used for our analysis:Ĥf3003dd2ed8dcb68133f95c14e28b168bd0f52e5ae9842f528d3f7866495ceaĪlthough some engines on VT have caught up with this sample, the majority still do not recognize it as malware at the time of writing, with only 12/59 detections.Īs the sample is not Notarized, the user will need to be socially engineered to override the Notarization check on macOS Catalina, something that commodity malware authors at least have become very successful at achieving. What ties these various campaigns together, aside from the use of FinFisher products, is that the targets are very frequently “human rights defenders”.Īlthough elements of the toolkit targeting macOS users have been known for some while to malware researchers, and some components of the macOS suite do not appear to be functional on the latest iterations of Apple’s desktop platform, our tests confirmed the malware samples shared by Amnesty will still launch and infect a macOS Catalina install, and that some of the dropped malware is not well-known to reputation services like VirusTotal. The company states that it only partners with “Law Enforcement and Intelligence Agencies” and has a “worldwide presence”.Īmnesty International and other civil rights organizations (e.g., the Citizen Lab), however, have noted FinSpy being used in campaigns targeting “activists, journalists and dissidents” in Egypt, Ethiopia, and the United Arab Emirates (UAE) among others.

In this post, we look at how to detect the macOS variant and list some previously unpublished IoCs.Īccording to FinFisher’s own website and marketing material, the company produces tools for “tactical intelligence gathering”, “strategic intelligence gathering”, and “deployment methods and exploitation”. The FinSpy tool was written with multiple capabilities in mind, with everything from keylogger, audio recording, camera and screenshot tools to a remote access shell, file enumeration and exfiltration functions. A report last week from human rights advocates Amnesty International brought to light a macOS variant of a cross-platform spyware suite known as FinSpy, developed and marketed by German-based outfit FinFisher.
