Malware pushers are experimenting with a novel way to infect Mac users that runs executable files that normally execute only on Windows computers.

Researchers from antivirus provider Trend Micro made that discovery after analyzing an app available on a Torrent site that promised to install Little Snitch, a firewall application for macOS. Stashed inside the DMG file was an EXE file that delivered a hidden payload. The researchers suspect the routine is designed to bypass Gatekeeper, a security feature built into macOS that requires apps to be code-signed before they can be installed. EXE files don’t undergo this verification, because Gatekeeper only inspects native macOS files.

Little Snitch 3.5.3 (4246) Significantly reduced CPU load of Little Snitch menu bar item. Improved searching for denied connections in Network Monitor. Improved compatibility with OS X 10.10.4. Fixed: Menu bar item sometimes got stuck in highlight mode. Fixed: Editing of multiple rule selections didn’t work in certain cases.

The calculator performs basic and advanced operations with fractions, expressions with fractions combined with integers, decimals, and mixed numbers. It also shows detailed step-by-step information about the fraction calculation procedure. Solve problems with two, three, or more fractions and numbers in one expression.

“We suspect that this specific malware can be used as an evasion technique for other attack or infection attempts to bypass some built-in safeguards such as digital certification checks, since it is an unsupported binary executable in Mac systems by design,” Trend Micro researchers Don Ladores and Luis Magisa wrote. “We think that the cybercriminals are still studying the development and opportunities from this malware bundled in apps and available in torrent sites, and therefore we will continue investigating how cybercriminals can use this information and routine.”

By default, EXE files won’t run on a Mac. The booby-trapped Little Snitch installer worked around this limitation by bundling the EXE file with a free framework known as Mono. Mono allows Windows executables to run on MacOS, Android, and a variety of other operating systems. It also provided the DLL mapping and other support required for the hidden EXE to execute and install the hidden payload. Interestingly, the researchers couldn’t get the same EXE to run on Windows.

The researchers wrote:

Currently, running EXE on other platforms may have a bigger impact on non-Windows systems such as MacOS. Normally, a mono framework installed in the system is required to compile or load executables and libraries. In this case, however, the bundling of the files with the said framework becomes a workaround to bypass the systems given EXE is not a recognized binary executable by MacOS’ security features. As for the native library differences between Windows and MacOS, mono framework supports DLL mapping to support Windows-only dependencies to their MacOS counterparts.

The Little Snitch installer the researchers analyzed collected a wealth of system details about the infected computer, including its unique ID, model name, and the apps installed. It then downloaded and installed various adware apps, some of which were disguised as legitimate versions of Little Snitch and Adobe’s Flash Media Player.

While the Trend Micro researchers specifically mentioned Gatekeeper as one of the protections the EXE may be designed to bypass, Thomas Reed, director of Mac offerings at Malwarebytes, said definitively that there's no such bypass taking place. Patrick Wardle, a macOS security expert and chief research officer at Digita Security, agreed. They say there's no bypass because the EXE's main delivery mechanism is a standard machO binary that Gatekeeper inspects and will block if it's unsigned or has a revoked certificate.

Still, the discovery underscores the cat-and-mouse game that plays out almost endlessly between hackers and developers. As soon as developers devise a new way to protect users, hackers look for ways to get around it. When hackers are successful, developers then introduce a fix that remains in place until hackers find a new way to skirt the protection.

In 2015, macOS security expert Patrick Wardle reported a drop-dead simple way for malware to bypass Gatekeeper. The technique worked by bundling a signed executable with a non-signed executable. Apple fixed the bypass weakness after Wardle reported it. Company representatives didn’t immediately respond to an email seeking comment about the reported ability of EXE files to bypass Gatekeeper.

Little Snitch 3.5.3

Little Snitch gives you control over your private outgoing data.

Track background activity
As soon as your computer connects to the Internet, applications often have permission to send any information wherever they need to. Little Snitch takes note of this activity and allows you to decide for yourself what happens with this data.

Control your network
Choose to allow or deny connections, or define a rule how to handle similar, future connection attempts. Little Snitch runs inconspicuously in the background and it can even detect network-related activity of viruses, trojans, and other malware.

WHAT’S NEW

Version 3.5.3:

• Significantly reduced CPU load of Little Snitch menu bar item.
• Improved searching for denied connections in Network Monitor.
• Improved compatibility with OS X 10.10.4.
• Fixed: Menu bar item sometimes got stuck in highlight mode.
• Fixed: Editing of multiple rule selections didn’t work in certain cases.
• Other stability improvements and bug fixes.
