.System Files Ransomware – Update February 2018

Malware researchers have spotted a slight change in the detections with the latest CryptoMix variant – now all encrypted files have the extension .SYSTEM written with capital letters. The extension is the same as before, but is no longer written with small letters. Other changes have not been spotted. However, more and more people keep falling victim to the .SYSTEM CryptoMix ransomware threat in 2018.

System Ransomware – Infection Spread

System ransomware could spread its infection with various methods. A payload dropper which initiates the malicious script for this ransomware is being spread around the Internet, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your computer will become infected.

System ransomware might also distribute its payload file on social media and file-sharing services. Freeware which is found on the Web can be presented as helpful also be hiding the malicious script for the cryptovirus. Refrain from opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything that seems out of the ordinary. You should read the tips for preventing ransomware found in our forums.

System Ransomware – Detailed Overview

System is a virus that could encrypt your files and extort you to pay a ransom to get them back to normal. The ransomware is a variant of the CryptoMix malware family, researchers have discovered.

The following email is used for contacting the cybercriminals:

• [email protected]
• [email protected]
• [email protected]
• [email protected]
• [email protected]

System ransomware might make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.

→HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

Below you will see some of the commands which the ransomware runs to stop important Windows processes:

• sc stop wscsvc
• sc stop WinDefend
• sc stop wuauserv
• sc stop BITS
• sc stop ERSvc
• sc stop VVS
• sc stop WerSvc

That ransom note is inside a file named _HELP_INSTRUCTION.TXT can be seen from the below image:

The note reads the following:

Hello!

Attention! All Your data was encrypted!

IMPORTANT: DO NOT USE ANY PUBLIC SOFTWARE! IT MAY DAMAGE YOUR DATA FOREVER!

DECRYPT-ID-dcd3c0a1-6659-4b92-950a-7a6e2f39bec9 number

The note of the System ransomware states that your files are encrypted. Different e-mail addresses are left as a way to contact the cybercriminals to pay a ransom and supposedly unlock your files. However, you should NOT under any circumstances pay any ransom. Your files may not get restored, and nobody could guarantee that. Moreover, giving money to cybercriminals will likely motivate them to create more ransomware viruses or do other criminal acts.

System Ransomware – Encryption Process

The encryption process implemented by the System ransomware is to encrypt your files with the AES algorithm and then use RSA-1024 encryption keys to lock them further.

The targeted extensions of files which are sought to get encrypted are currently unknown and if a list is discovered, it will be posted here as the article gets updated. The files used most by users and which are probably encrypted are from the following categories:

• Document files
• Audio files
• Video files
• Image files
• Backup files
• Banking credentials and data

Every single file that gets encrypted will receive the same extension appended to it, which is .System. An example of an encrypted file’s name would be the following:

• 9ABFV8DF4FSJK1236AAB15C2080F32M.System

The System cryptovirus is set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→C:\Windows\System32\cmd.exe” /C vssadmin.exe Delete Shadows /All /Quiet

The command stated above is executed which makes the encryption process more efficient as it eliminates one of the ways for restoring your data. If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially recover your data.

Remove System Ransomware and Restore .System Files

If your computer got infected with the System ransomware virus, you should have a bit of experience in removing malware. You should get rid of this ransomware as quickly as possible before it can have the chance to spread further and infect other computers. You should remove the ransomware and follow the step-by-step instructions guide provided below.

Manually delete System from your computer

Note! Substantial notification about the System threat: Manual removal of System requires interference with system files and registries. Thus, it can cause damage to your PC. Even if your computer skills are not at a professional level, don’t worry. You can do the removal yourself just in 5 minutes, using a malware removal tool.

1. Boot Your PC In Safe Mode to isolate and remove System files and objects

Boot Your PC Into Safe Mode

1. For Windows 7,XP and Vista. 2. For Windows 8, 8.1 and 10. Fix registry entries created by System on your PC.

For Windows XP, Vista, 7 systems:

1. Remove all CDs and DVDs, and then Restart your PC from the “Start” menu.
2. Select one of the two options provided below:

– For PCs with a single operating system: Press “F8” repeatedly after the first boot screen shows up during the restart of your computer. In case the Windows logo appears on the screen, you have to repeat the same task again.

– For PCs with multiple operating systems: Тhe arrow keys will help you select the operating system you prefer to start in Safe Mode. Press “F8” just as described for a single operating system.

3. As the “Advanced Boot Options” screen appears, select the Safe Mode option you want using the arrow keys. As you make your selection, press “Enter“.

4. Log on to your computer using your administrator account

While your computer is in Safe Mode, the words “Safe Mode” will appear in all four corners of your screen.

Step 1: Open the Start Menu

Step 2: Whilst holding down Shift button, click on Power and then click on Restart.
Step 3: After reboot, the aftermentioned menu will appear. From there you should choose Troubleshoot.

Step 4: You will see the Troubleshoot menu. From this menu you can choose Advanced Options.

Step 5: After the Advanced Options menu appears, click on Startup Settings.

Step 6: Click on Restart.

Step 7: A menu will appear upon reboot. You should choose Safe Mode by pressing its corresponding number and the machine will restart.

Some malicious scripts may modify the registry entries of your computer to change different settings. This is why manual clean up of your Windows Registry Database is strongly recommended. Since the tutorial on how to do this is a bit lenghty, we recommend following our instructive article about fixing registry entries.

2. Find malicious files created by System on your PC

Find malicious files created by System

1. For Windows 8, 8.1 and 10. 2. For Windows 7,XP and Vista.

2. Restore files encrypted by System

Restore Files Encrypted by System

Ransomware infections like System aim to encrypt your files using an encryption algorithm which may be very difficult to directly decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that they may not be 100% effective but they may help you little or a lot in some situations.

Method 1: Scanning your drive’s sectors by using Data Recovery software.
Another method of restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:

• Stellar Phoenix Data Recovery Technicians License(Pro version with more features)
• Stellar Phoenix Windows Data Recovery
• Stellar Phoenix Photo Recovery

Method 2: Trying Kaspersky and EmsiSoft’s decryptors.
If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:

• Kaspersky Decryptors
• Emsisoft Decryptors

Urgent! It is strongly advisable to first remove the System threat before attempting any decryption, since it may interfere with system files and registries. You can do the removal yourself just in 5 minutes, using an advanced malware removal tool.

Method 3: Using Shadow Explorer

To restore your data in case you have backup set up, it is important to check for shadow copies in Windows using this software if ransomware has not deleted them:

• Shadow Explorer

Method 4: Finding System decryption key while it communicates it via a network sniffing software.

Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
