How to remove the BlackNix Remote Access Trojan (RAT)
Written by Tomas Meskauskas on (updated)
What is the BlackNix RAT?
BlackNix is a Remote Access Trojan (RAT) that allows cyber criminals to gain access and control over infected devices. BlackNix is high-risk malware with malicious capabilities, which can cause serious issues.
RAT-type malicious programs have varied functions that enable a wide range of abuse over the infected machine. This Trojan can control the Windows Operating System. For example, it can close, rename, "freeze/unfreeze", copy the activation key and terminate the operating system.
BlackNix can interact with and modify (e.g. refresh, rename, delete, etc.) the Windows Registry. This database contains information, settings and other values of software and hardware installed on the system. It can similarly manage personal files as well.
The malware can also start or end application processes. BlackNix can even uninstall applications. Through its capability to run shellcode, it can manipulate the functionality of exploited programs. Another function is data exfiltration and infiltration (via upload/download).
This malicious software can cause chain infections. The downloaded/installed malware can include ransomware, cryptominers and other malicious content. As the program can record key strokes (keylogging), it can learn typed information (e.g. log-ins and passwords).
In this way, the cyber criminals using BlackNix can steal victims' communication, social networking, social media and financial accounts. Stored passwords on Mozilla Firefox (and potentially other browsers) are also susceptible to theft. Another feature of this RAT is audio recording through hardware integrated into, or connected to, the computer.
These are just some of the main functions of BlackNix. To summarize, BlackNix infections can lead to serious problems: significant system damage, data loss, serious privacy issues, financial loss (through hijacked financial/e-commerce accounts, ransom demands, blackmail, etc.), identity theft and many others.
If you suspect that BlackNix has already infected the device, remove it immediately.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Combo Cleaner.
Xtreme, ShadowTechRAT, and PiXie are some other examples of malicious programs categorized as RATs. While their capabilities differ, all malware programs have the same purpose: to generate revenue for the cyber criminals using them.
Regardless of their specific functions, such programs are highly dangerous and must be eliminated from operating systems without delay.
How did BlackNix infiltrate my computer?
The most common proliferation methods of malware (including RATs) are via spam campaigns, illegal activation tools ("cracks"), bogus updaters and untrusted download channels. The term "spam campaign" defines large scale operations during which thousands of deceptive emails are sent.
These messages are typically presented as "official", "priority", "important", "urgent" and similar. This mail might even claim to be from representatives of popular companies/services in attempts to further the impression of legitimacy. The emails have infectious files attached (or contain download links of malicious content)
Fake updaters infect systems by exploiting flaws of outdated products or simply by installing malware rather than the updates.
Malicious programs are often unintentionally downloaded (when disguised as or packed with normal content) from untrusted download sources such as unofficial and free file-hosting websites, P2P sharing networks (BitTorrent, Gnutella, eMule, etc.) and other third party downloaders.
How to avoid installation of malware
Dubious and irrelevant emails should not be opened, and especially if there are any attachments or links present in them - doing so can trigger infection processes. You are advised to use only verified download channels, as opposed to Peer-to-Peer sharing networks or other third party downloaders.
Additionally, activate and update programs using functions/tools provided by legitimate developers. Illegal activation ("cracking") tools and third party updaters should be avoided, as they can stealthily download/install malware. To ensure device and user safety, have a reputable anti-virus/anti-spyware suite installed and kept up to date.
Use this software for regular system scans and removal of detected threats/issues. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?
Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically.
To remove this malware we recommend using Combo Cleaner Antivirus for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.
These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
