CinaRAT virus removal guide
What is CinaRAT?
CinaRAT is the name of a Remote Administration Trojan that is very similar to another RAT called Quasar. Typically, RATs allow the attackers to access and control infected machines remotely. After successful installation, cybercriminals can use CinaRAT to manage files, access Command Prompt, Task Manager, and other Windows features, steal saved passwords from web browsers and FTP software, and log keystrokes. It is known that CinaRAT uses certain techniques to avoid antivirus detection.
The attackers can use CinaRAT to open, download, delete, rename, move files that are stored on the infected machine, steal saved passwords from Google Chrome, Mozilla Firefox and possibly other browsers, and installed FTP programs (like FileZilla). Also, they can use it to record keyboard input/keys pressed with the connected keyboard, open Command Prompt and use it to execute various commands, access Task Manager and run or terminate processes (or perform other actions), and use other Windows features. It means that with the help of CinaRAT cybercriminals could steal personals accounts (for example, email, banking, social media accounts). Depending on the type of stolen accounts, they could be misused to send phishing, malspam emails, make fraudulent purchases, transactions, steal identities, trick other people into making monetary transactions, or for other malicious purposes.
Also, the attackers could use CinaRAT to install some other malware on the machine, for example, ransomware, or other unwanted software like a cryptocurrency miner. Since CinaRAT comes with a keylogging feature, it could be used to steal login credentials (such as usernames, email addresses, passwords), credit card details, and other sensitive details that victims would enter using their keyboard. Therefore, victims of the CinaRAT attack may lose access to a variety of personal accounts, have their computers infected with other malware, suffer monetary loss, lose personal, important files, have their identities stolen, and encounter other serious problems. Therefore, when malware like CinaRAT is installed on the operating system, it has to be eliminated immediately.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
More examples of Remote Administration Trojans (also known as Remote Administration Trojans) are Orcus, ViperSoftX and ElectroRAT. As a rule, RATs are used to steal sensitive information and to distribute (download and install) other malware. In most cases, victims are not aware that their computer is infected with a RAT because malware of this type often runs in the system background silently and is capable of avoiding antivirus detection. RATs are usually downloaded and installed unknowingly, accidentally.
How did CinaRAT infiltrate my computer?
It is known that CinaRAT is distributed through some ISO archive file that contains a malicious Visual Basic script (VBScript) responsible for loading, persistence, and evasion. That VBScript is designed to load a remote .NET DLL executable that injects CinaRAT into a legitimate Windows process (by being injected into system process malware avoids antivirus detection). Research shows that there are at least four different versions of the CinaRAT that can be injected through the .NET DLL (.net loader). It is unknown how cybercriminals distribute that ISO archive file, which contains files necessary for the installation of CinaRAT. However, it is very likely that they do it using a malspam camapaign (emails that contain some malicious attachment or download link for a malicious file), pirated software (or 'crackin' tools), unreliable sources for downloading files, programs (such as Peer-to-Peer networks, third party downloaders, unofficial pages, free file hosting pages, etc.), or fake software updating tools.
How to avoid installation of malware?
Do not open email attachments or website links in received emails that are not relevant, sent from unknown, suspicious addresses, etc. In other words, analyze emails before opening files or clicking links in them. Download files and software only from legitimate, official pages and use direct links. Avoid downloading software via third party downloaders, Peer-to-Peer networks (like torrent clients, eMule), free file hosting pages, from unofficial web pages, etc., or installing it via third-party installers. Update and activate installed software with tools or implemented functions provided by its official developers. Third-party, unofficial tools can be malicious (contain malware/have malicious code injected into them). Also, it is not legal to use 'cracking' tools or pirate software. Run virus scans regularly and make sure to do it using up-to-date and reputable antivirus or anti-spyware software. 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:
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 Malwarebytes for Windows.
