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:

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!

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.
