Milum virus removal guide
What is Milum RAT?
Milum is the name of a Remote Access Trojan (RAT). Malware within this category is designed to allow its users (i.e. cyber criminals) remote access and control over the infected machine. Trojans of this type are deemed to be highly dangerous; they have varied abilities that can be used to cause especially severe issues. Milum RAT has been observed targeting industrial organizations and similar entities in the Middle East. Additionally, during research it was noted that this malware was primarily used to gather data.
Milum RAT can receive commands from the C&C (command and control ) server controlled by cyber criminals, which allows it a certain level of control over the infected system. It can also send command status and result reports. This malware has data exfiltration abilities and as mentioned in the introduction, Milum has been mainly employed for this purpose. Milum can learn information, relating to the system: operating system version, network and user account names, anti-virus and similar security products that are installed onto it, etc. This RAT can collect information on various files (e.g. system, hidden, read-only, etc.), which are stored in the device. The gathered data is then sent to the C&C server. What misuse and issues this can cause depend on the stolen information itself and the modus operandi of the cyber criminals using such remote access tools like Milum. For example, when leveraged against organizations, institutions, businesses and the like - the collected data can be held for ransom, under threat of being leaked/sold to competitors or simply publicized. Ransom/Blackmail models may be used for average users as well, if the obtained information is particularly compromising and/or sensitive. Furthermore, the intel can be employed to tailor malicious scams, most likely to entrap the users. What is more, Milum RAT has the ability to update itself, hence its list of features can grow. If it is known or suspected that Milum (or other malware) has already infected the system, it is strongly recommended to use an anti-virus software to remove it immediately.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
BlackNET, PlugX, Koadic and Xtreme are a few examples of other remote access trojans. Malicious programs of this type can have a variety of heinous abilities, such as: control/management of installed software, connected hardware (e.g. webcams, microphones, etc.) and of the infected system itself; keylogging; data exfiltration and infiltration (the latter can be used to cause chain infections, i.e. to download/install trojans, ransomware, cryptominers and other malware), and so on. While they operate differently, these programs have but one purpose - to generate revenue for the cyber criminals behind them.

How to avoid installation of malware?
Suspicious and/or irrelevant emails should not be opened, especially any attachments or links present in them - as that can result in a high-risk infection. It is recommended to only use official and verified download sources. It is just as important to activate and update products with tools/functions provided by genuine developers. Illegal activation tools ("cracks") and third party updaters are advised against use, since they are often used to proliferate malicious programs. To protect device integrity and user safety, it is crucial to have a dependable anti-virus/anti-spyware suite installed. This software must be kept up-to-date, used to run regular systems scans and to remove detected/potential threats. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes 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 Malwarebytes 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:

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 Malwarebytes for Windows.
