How to remove the "Mac EXE Virus" from your operating system

What is "Mac EXE Virus"?

Mac EXE Virus is a rogue application that infiltrates Mac computers and gathers various system-related data. Note that this malware is proliferated using an executable (.exe or EXE) file, which is developed for the Windows Operating System. MacOS does not support this format by default.

This malware is distributed using an installation setup of a cracked Little Snitch version, which is a popular Mac/Windows Firewall app. Research shows that, as well as proliferating Mac EXE Virus, the cracked version of Little Snitch is also used to distribute adware and browser hijackers (e.g., TapuFind, Search Operator).

"Mac EXE Virus" overview

Mac EXE Virus functionality is rather basic. After successful infiltration, Mac EXE Virus immediately gathers various information about the system (the list of collected information is below) and sends it to a remote server. In addition, Mac EXE Virus checks if there are certain applications installed (the list of searched apps is below) and also sends details to a remote server.

Mac EXE Virus then connects to the remote server and downloads several files to the "~/Library/X2441139MAC/Temp/" directory. At time of research, Mac EXE Virus gathered information that is not particularly sensitive (e.g., processor details, memory, etc.), however, it is promoted using a quite unique malware distribution technique.

Therefore, there is a high probability that this virus is either still in development or is used to test whether the malware distribution method is effective. If Mac EXE Virus is still being developed, there is a high probability that it will start gathering more sensitive data, such as saved logins/passwords, browsing history, etc.

Furthermore, since it is capable of downloading various data, it might be used to proliferate other viruses. Therefore, this virus should be eliminated immediately.

Similar software examples

The internet is full of malware that shares similarities with Mac EXE Virus (e.g., Speakup, Shlayer, CoinTicker, CookieMiner, and many others).

These viruses are developed by different cyber criminals and, thus, their behavior might also differ - some gather information, others misuse the system to stealthily mine cryptocurrency, proliferate viruses, or perform a number of these activities. In any case, all pose a direct threat to your privacy and browsing safety. Therefore, you should eliminate these threats immediately.

How did Mac Exe Virus infiltrate my computer?

As mentioned above, Mac EXE Virus is distributed using an executable (.exe) file (hence its name). This file format runs on the Windows Operating System.

Note that running it on Linux, MacOS, and other operating systems will not work - users will simply encounter an error, however, MacOS security systems (such as Gatekeeper) check only those files that run on MacOS (e.g., .dmg, .app, and so on). Therefore, formats such as .exe are not scanned. Therefore, cyber criminals can bypass the security systems.

The malicious Little Snitch installer, through which which Mac EXE Virus is promoted, is a MacOS application, however, its content includes the aforementioned executable. Installer also contains Mono - .NET framework-based software that is used to run Microsoft .NET applications on other platforms (such as MacOS, Linux, Android, Solaris, etc.).

Installer employs Mono to run the malicious executable which places the Mac EXE Virus virus into the system. As mentioned, this distribution method is quite unusual - malware of this type is often distributed using trojans, software cracks, and spam email campaigns. Trojans cause "chain infections" (they infiltrate computers and continually inject additional malware).

Spam campaigns proliferate viruses via malicious attachments. Criminals send hundreds of thousands of emails with deceptive messages and infectious attachments (e.g., PDFs, Microsoft Office documents, JavaScript files, or similar). They attempt to convince recipients into opening the attached files (or links that lead to these files), thus resulting in malware infections.

Software cracks bypass paid software activation, however, criminals often use these tools to proliferate malware. Rather than gaining access to paid features, users end up infecting their computers.

How to avoid installation of potentially unwanted applications?

Caution is the key to computer safety. Therefore, pay close attention when browsing the internet and downloading/installing software. We strongly recommend that you download applications from official sources only, using direct download links. Third party downloaders/installers are often used to proliferate viruses, and thus these tools should never be used.

Note that most set-ups that the Mac EXE Virus is distributed through are downloadable on various publicly-accessible torrent sites that are not safe. This is a clear example of cyber criminals proliferating malware through third party download sources. Keep installed applications updated.

To achieve this, however, use only implemented functions or tools provided by the official developer. Never use software cracking tools, since: 1) software piracy is considered a cyber crime, and; 2) there is a high risk of computer infections. Think twice before opening email attachments.

Files that are irrelevant and those received from suspicious/unrecognizable email addresses should never be opened. Having a legitimate anti-virus/anti-spyware suite installed and running at all times is also extremely important, since these tools can detect and eliminate malware before it does any harm.

If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
