EXE is the official executable file format used for Windows to signify that they only run on Windows platforms, and to serve as a security feature. By default, attempting to run an EXE file on a Mac or Linux OS will only show an error notification.

However, we found EXE files in the wild delivering malicious payload on macOS recently. While no specific attack pattern is seen, our telemetry showed the highest numbers for infections to be in the United Kingdom, Australia, Armenia, Luxembourg, South Africa, and the United States.

Behavior

The samples pose as installers of popular apps and are often available for download from various torrent websites. Examples of the applications they pose as are as follows:

• Paragon_NTFS_for_Mac_OS_Sierra_Fully_Activated.zip
• Wondershare_Filmora_924_Patched_Mac_OSX_X.zip
• LennarDigital_Sylenth1_VSTi_AU_v3_203_MAC_OSX.zip
• Sylenth1_v331_Purple_Skin__Sound_Radix_32Lives_v109.zip
• TORRENTINSTANT.COM+-+Traktor_Pro_2_for_MAC_v321.zip
• Little_Snitch_583_MAC_OS_X.zip

When the downloaded .ZIP file is extracted, it contains a .DMG file hosting the supposed installer of the spoofed app.

Mac dmg download. Nov 13, 2007  ok, So I have a read-only DMG that I need to be able to edit the contents of. I have duplicated this image as many ways I can think of. I have used Carbon Copy Cloner to create a (Read-Write) sparse image of it, when I get info on the DMG it says I (my user) have read-write access.

Inspecting the installer contents, we found the unusual presence of the .EXE file bundled inside the app, verified to be a Windows executable responsible for the malicious payload.

When the installer is executed, the main file also launched the executable as it is enabled by the mono framework included in the bundle. This framework allows the execution of Microsoft .NET applications across platforms such as OSX.

Once run, the malware collects the following system information:

• ModelName
• ModelIdentifier
• ProcessorSpeed
• ProcessorDetails
• NumberofProcessors
• NumberofCores
• Memory
• BootROMVersion
• SMCVersion
• SerialNumber
• UUID

Under the /Application directory, the malware also scans for all the basic and installed apps and sends all the information to the C&C server:

• App Store.app
• Automator.app
• Calculator.app
• Calendar.app
• Chess.app
• Contacts.app
• DVD Player.app
• Dashboard.app
• FaceTime.app
• Font Book.app
• Image Capture.app
• iTunes.app
• Launchpad.app
• Mail.app
• Maps.app
• Messages.app
• Mission Control.app
• Notes.app
• Photo Booth.app
• Photos.app
• Preview.app
• QuickTime Player.app
• Reminders.app
• Safari.app
• Siri.app
• Stickies.app
• System Preferences.app
• TextEdit.app
• Time Machine.app
• UtilitiesiBooks.app

It downloads the following files from the Internet and saves it to the directory ~/Library/X2441139MAC/Temp/:

• hxxp://install.osxappdownload.com/download/mcwnet
• hxxp://reiteration-a.akamaihd.net/INSREZBHAZUIKGLAASDZFAHUYDWNBYTRWMFSOGZQNJYCAP/FlashPlayer.dmg
• hxxp://cdn.macapproduct.com/installer/macsearch.dmg

These .DMG files are mounted and executed as soon as they are ready, as well as displaying a PUA during execution.

This malware runs specifically to target Mac users. Attempting to run the sample in Windows displays an error notification.

Currently, running EXE on other platforms would have no impact on non-Windows systems such as MacOS. A mono framework installed in the system is required to compile or load these executables and libraries. In this case, however, the bundling of the said framework with the malicious files becomes a workaround to enable EXE files to run on Mac systems. As for the native library differences between Windows and MacOS, the mono framework supports DLL mapping to support Windows-only dependencies to their MacOS counterparts. Overall, this technique may be done to overcome a malicious user’s Objective-c coding limitations.

Conclusion

We suspect that this specific malware can be used for future inter-platform attacks, where a single executable can perform its payload on different operating systems. We believe that the cybercriminals are still studying the development and opportunities from this malware bundled in apps and available in torrent sites. We will continue investigating how cybercriminals can use this information and routine. Users should avoid or refrain from downloading files, programs, and software from unverified sources and websites, and install a multi-layered protection for their individual and enterprise systems.

Indicators of Compromise

Mac users have enjoyed a long run of fairly virus-free computing, but it shouldn’t be taken for granted that there is no virus. While Apple has kept a close grip in the App Store, some malware, on rare occasions, still make it up there. Likewise, the macOS Gatekeeper is only useful when you do not override its settings, but that will restrict you to only install apps from the App store. So if you download an app that didn’t come from the App Store, how can you check whether it is safe to install?

About Suspicious Package

Suspicious Package is a special-purpose utility program designed to check macOS packages – software files that install application programs. Packages typically contain several components, including the app itself, scripts that automate the installation process, and other files the program needs. Although the macOS packaging system is an efficient way for developers to organize all the pieces that go into an app, it’s also possible for hackers to subvert it by inserting their own malicious programming. Suspicious Package allows you to inspect the contents of any macOS package, potentially heading off a malware infection.

Download and Installation

The Suspicious Package app is available for download directly from mothersruin.com. To install it, you may have to temporarily bypass the macOS Gatekeeper which normally prevents you from installing non-App Store programs by accident. In “System Preferences” go to “Security & Privacy -> General -> Allow apps downloaded from:” and change the setting to “App Store and identified developers.” When you open the Suspicious Package dmg file, you’ll see the warning, “SuspiciousPackage.dmg blocked from opening because it is not from an identified developer.” Click the “Open Anyway” button to install the program.

Quick Look

The “Quick Look” feature displays a package summary from the Finder without having to launch the Suspicious Package app itself. This is a handy time-saver if you have several packages to check. To use Quick Look, highlight the package you want to evaluate from the Finder, then find the Quick Look item in the Finder’s File menu, or press “command + Y.”

Check a Package

To check a package you’ve downloaded, launch Suspicious Package. From the “File” menu, select “Open,” then browse your Downloads or other folder for a package file to inspect. Suspicious Package analyzes the file, then displays a set of tabs: “Package Info,” “All Files,” and “All Scripts.” If the app detects problems with the package, the Review icon indicates a warning.

Package Info

The Package Info tab gives an overview of what’s in the package. It shows how many items are installed, how many scripts it uses, and whether it is signed or not. It lists when the package was downloaded and the browser name. Finally, if the package has problems, Package Info shows the number of warnings given.

All Files

Resembling a Finder window, All Files shows all the files stored in the package, including the application itself, supporting files, and folder organization. Click on any folder to see its contents.

All Scripts

The All Scripts tab lists all the macOS shell scripts used to install the package. Each script is a mini-program containing text commands used to copy, create, and delete files. Click on a script name to see the instructions. The File menu includes options to edit a script, should you want to.

Unsigned Packages

When using Suspicious Package, you may see a warning that says the package isn’t signed. Package signing is a feature Apple developed so software developers can “stamp” their programs with a digital signature officially tying the application to the people who wrote it. The signature gives confidence that the software is legit and not a cheap knock-off. In fact, Apple requires signatures for all software in the App Store. Some developers, however, don’t spend the extra effort needed to sign their software. Many unsigned packages, including open-source and freeware programs, are actually okay to use. On the other hand, if you’re buying Mac software from a major vendor, the absence of a signature is a big red flag.

Conclusion

The vast majority of Mac programs are free of malware. However, programs downloaded from third-party sites carry a small risk of spyware and other unwanted baggage. Though primarily aimed at technical users, Suspicious Package lets anyone evaluate macOS software for malware and other problems. The app clearly reveals the contents of a software package before you install it. Especially for Mac people who don’t use the App Store as their only source for software, Suspicious Package makes a worthy addition to your Mac toolbox.
