What kind of malware is DarkCrystal?
DarkCrystal, also known as dcRAT, is a Remote Access Trojan (RAT). Malware of this type enables remote access and control over an infected device. RATs can manipulate machines in various ways and can have likewise varied functionality.
DarkCrystal is a dangerous piece of software, which poses a significant threat to device and user safety.
More about DarkCrystal
The DarkCrystal RAT is a highly functional malicious program. To elaborate on some of this Trojan's main capabilities, it can manipulate hardware, software and data of the compromised computer.
Its hardware manipulation includes: opening/closing the CD-ROM drive door, recording audio via integrated/connected microphones and video/stills through webcams.
The malware can manage various files and folders: it can rename, move, delete them and create new ones. It can also exfiltrate and infiltrate (i.e. download and upload) files. If the stolen content is particularly sensitive, it might then be held for ransom. DarkCrystal can execute/run files and end already running processes.
Due to its capability to infiltrate files and execute them, it is possible that this RAT can be used to cause chain infections (i.e. infect the system with additional malware). The Trojan can take screenshots, rotate the screen, change the desktop wallpaper, hide the taskbar and desktop icons.
It can reboot/restart and shut down the system. Additionally, it can log-off the current user and create new user accounts. DarkCrystal targets certain browsers.
It can manipulate them by opening websites and extracting data stored in the browsers (e.g. browsing history, browser cookies, saved usernames and passwords, etc.). Another of DarkCrystal's data stealing capabilities is keylogging. I.e., it can record key strokes.
What damage a RAT can cause?
Typically, cyber criminals use saved log-in credentials and keylogging to target email, social media, social networking, messenger, data storage, e-commerce, online money transfers and banking accounts.
Hijacked communication/social accounts might be used to spread malware and/or to ask contacts/friends for loans - all under the guise of the real owner.
Accounts that deal with and/or store financial information are of particular interest, as through them criminals might be able to make fraudulent transactions and/or online purchases. To summarize, DarkCrystal infections can result in financial loss, serious privacy issues and identity theft.
If it is suspected or known that the DarkCrystal RAT (or other malicious software) has already infected the system, use anti-virus software to eliminate it immediately.

RATs in general
Imperium Metamorpher, Ratty, VanTom, DarkTrack and BlackRemote are some examples of other Remote Access Trojans. As mentioned, malicious programs within this classification can have various capabilities/features.
Therefore, how they are used, depends on the cyber criminals' goals and modus operandi. Regardless of how malware operates, the purpose is identical: to generate revenue to the individuals/groups behind it.
How did DarkCrystal infiltrate my computer?
Malware is proliferated using various techniques. The most common distribution methods are via spam campaigns, illegal activation ("cracking") tools, fake updates and dubious download channels. The term "spam campaign" defines a large-scale operation, during which thousands of scam emails are sent.
Rather than activating licensed products, illegal activation tools ("cracks") can download/install malware. Rogue updaters cause infections by exploiting weaknesses of outdated products and/or simply by installing malicious programs rather than the updates.
Malware (disguised as or packed with normal content) is often downloaded unintentionally from untrusted download sources such as unofficial and free file-hosting (freeware) sites, P2P sharing networks (BitTorrent, Gnutella, eMule, etc.) and other third party downloaders.
How to avoid installation of malware
Suspect and/or irrelevant emails must not be opened, especially those with any attachments or links found in them, as this can lead to high-risk infection. You are advised to use only official and verified download channels. All products must be activated and updated with tools/functions provided by legitimate developers.
Illegal activation tools ("cracks") and third party updaters should be avoided, since they are commonly used to proliferate malware. To ensure device integrity and user safety, it is paramount to have reputable anti-virus software installed and kept up to date.
Furthermore, this software must be used to run regular system scans and to remove detected/potential threats. 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.
