What is Luminosity?
Luminosity (also known as LuminosityLink) is a Remote Access Trojan (RAT), which was developed some years ago. At that time, cyber criminals could purchase Luminosity from its developers for $40, however, this RAT is no longer for sale. Note that many cyber criminals still use its 'cracked' versions.
RATs such as Luminosity are employed by cyber criminals with malicious intent to infect systems with other malware, steal sensitive information by logging keystrokes, and so on.
When installed, Luminosity allows cyber criminals to take control over the infected computer remotely. Therefore, the criminals responsible can access files, cameras, turn off and restart a computer, download and execute various files, log keystrokes and perform other actions.
Research shows that most cyber criminals use Luminosity to log keystrokes and install additional malware. The keystroke logging feature allows them to record keyboard input and use it to steal any data that users enter via the keyboard. In most cases, this feature is used to steal passwords, credit card details and/or other information of this kind.
They use the details to steal identities, make fraudulent purchases and transactions, or they sell it to third parties (other criminals). People might then become victims of identity theft, suffer monetary loss, experience serious online privacy issues and other problems.
Furthermore, Luminosity is also used to spread malware. Cyber criminals can infect the user's computer with other malicious programs such as Trojans, ransomware or high-risk malware. If there is any reason to believe that Luminosity might be installed on the operating system, it should be eliminated immediately.

There are many legitimate Remote Administration/Access Tools, however, even they can be used with malicious intent. Typically, cyber criminals use this software to steal as much sensitive information as possible and infect computers with other malware, which enables them to generate revenue in various ways. Some examples of other RATs are PoetRAT, Pekraut and FireBird.
How did Luminosity infiltrate my computer?
It is very likely that cyber criminals attempt to trick users into installing Luminosity through spam campaigns, untrusted software download channels, unofficial updating tools or software activation ('cracking') tools. One of the most common ways to deceive visitors into installing malicious software is to send emails that contain malicious attachments.
Furthermore, malicious programs can be proliferated through Peer-to-Peer networks such as torrents, eMule, freeware download websites, free file hosting websites, third party downloaders and other similar channels and sources. People who use such channels to download files and programs risk downloading malicious files that are disguised as harmless.
When opened, the files infect systems with malware. Fake/unofficial updaters can infect computers by exploiting bugs/flaws of outdated software, or by downloading and installing malicious software rather than updates and fixes.
Various unofficial activation tools (also known as 'cracking' tools) are used to distribute malicious programs. People who use them often install malware rather than activating any licensed software.
How to avoid installation of malware
Attachments or web links that are included in irrelevant emails should not be trusted or opened, especially if the emails are sent from unknown, suspicious addresses. All programs and files should be downloaded from official, trustworthy websites. It is not safe to use other channels.
Software must be updated through tools/functions that are designed by official developers. The same applies to software activation. Various 'cracking' unofficial activation tools often infect systems with malicious programs.
Furthermore, it is illegal to activate any licensed software with them. Keep computers safe by regularly scanning them with a reputable antivirus or anti-spyware suite and ensure that this security software is up to date. 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.

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 Combo Cleaner Antivirus for Windows.
