How to remove "Mac EXE Virus" from Mac?

What is "Mac EXE Virus"?

Mac EXE Virus is a rogue application that infiltrates Mac computers and gathers various system-related data. What's interesting is that this malware is proliferated using an executable (.exe or EXE) file, which is developed for Windows operating system and MacOS doesn't 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 results show that aside from proliferating Mac EXE Virus, cracked version of Little Snitch was also used to distribute adware and browser hijackers (e.g., TapuFind, Search Operator).

Mac EXE Virus scam

Mac EXE Virus's functionality is rather basic. After successful infiltration, Mac EXE Virus instantly gathers various information about the system (list of collected info below) and sends it to a remote server. In addition, Mac EXE Virus checks if there are certain applications installed or not (list of searched apps below) and also sends details to a remote server. After doing so, Mac EXE Virus connects to the remote server and downloads several files to the "~/Library/X2441139MAC/Temp/" directory. At the time of research Mac EXE Virus was gathering information that isn't very sensitive (e.g., processor details, memory, etc.) However, as mentioned above, Mac EXE Virus is promoted using a rather unique malware distribution technique. Therefore, there's a high credibility that this virus is either still in development or it is used in order to test whether the said malware distribution method is actually effective. In case Mac EXE Virus is still being developed, there's a high credibility that it will start gathering more sensitive data, such as saved logins/passwords, browsing history, etc. Moreover, since it is capable of downloading various data, it may be used to spread other viruses. Thus, this virus should be eliminated as soon as possible.

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, thus, their behavior might be slightly different - some gather information, some abuse the system to stealthily mine cryptocurrency, some proliferate other viruses, others do few or all of these things. However, at the end of the day all of these viruses have one thing in common: they pose direct threat to user's privacy and web browsing safety. Therefore, elimination is paramount.

How did Mac Exe Virus infiltrate my computer?

As mentioned above, Mac EXE Virus is distributed using an executable (.exe) file (thus it's name). This file format is designed to run on Windows operating system, meaning that running it on Linux, MacOS or any other operating system will not work - users will simply encounter an error. However, it is worth mentioning that MacOS security systems (such as Gatekeeper) are designed to check only those files that are designed to run on MacOS (e.g., .dmg, .app, and so forth). In other words, formats like .exe aren't being scanned and, thus, cyber criminals can easily bypass the security systems. The malicious Little Snitch installer which Mac EXE Virus is promoted through is a MacOS application. However, its content includes the aforementioned executable. Installer also contains Mono - a .NET framework-based software that is used to run Microsoft .NET applications on other platforms (such as MacOS, Linux, Android, Solaris, and so on so forth). Installer employs Mono to run the malicious executable which drops Mac EXE Virus virus into the system. As said before, this distribution method is rather unusual - malware of this type is very likely to be distributed using trojans, software cracks, and email spam campaigns. Trojans are designed to cause "chain infections" (they infiltrate computers and continually inject additional malware). Spam campaigns proliferate viruses via malicious attachments. Crooks 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), what eventually results in a malware infection. Software cracks are meant to bypass paid software activation. However, crooks often use such tools to spread malware. Therefore, rather than gaining access to paid features, users often end up infecting their computers.

How to avoid installation of potentially unwanted applications?

In order to prevent this situation users must firstly realize that caution is the key to computer safety. Therefore, always pay close attention when browsing the Internet and downloading/installing software. We highly recommend to download applications only from official sources, using direct download links. Third party downloaders/installers are often used to spread viruses, which is why such tools should never be used. Note that most of setups that Mac EXE Virus was distributed through were downloadable on various publicly-accessible torrent sites that aren't safe. This is a great example of cyber criminals proliferating malware through third party download sources. Moreover, be sure to keep installed applications updated. To achieve this, however, use only implemented functions or tools provided by the official developer. It is advised to never use any software cracking tools because of two reasons: 1) software piracy is considered a cyber crime; 2) there's a high risk of computer infections. Always think twice before opening email attachments. Files that aren't relevant 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 such tools are more than likely to detect and eliminate malware before it does any harm. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
