This article should be able to help you remove the SecretSystem ransomware infection from your computer and aims to show you how to restore .slvpawned encrypted files.

A ransomware virus detected in the middle of May 2017 has been reported to use the .slvpawned file extension which it adds to the files encrypted by it. The virus aims to encode the important documents, videos, music, photos and other types of files on the computer so that they are no longer able to be opened. After the encryption process is complete, the ransomware virus leaves behind a ransom note in which it demands victims to pay a hefty ransom fee in order to get the files back – 500 U.S. dollars. In case you have become a victim of this ransomware infection, recommendations are to read this article thoroughly.

Update May 2017! It has been confirmed that the SecretSystem ransomware is a new variant of the “Stupid Ransomware” family and the decrypter for these viruses has been updated, meaning you can now decrypt your files for free. To remove this virus and decrypt your files, follow the instructions on this web link.

Distribution of SecretSystem Virus

In order to be spread and to massively infect victims on a global scale, the ransomware infection aims to perform multiple different types of tactics in order to slither in a computer system unnoticed:

  • Intermediary malware that drops the payload(Droppers, Loaders, etc.)
  • Obfuscators for the malicious files to hide the activity of the virus from various antivirus programs.
  • Spamming software that spreads the virus via referral spam or e-mail.
  • E-mail addresses to spam from.
  • A pre-set list of targeted e-mail addresses to be spammed.
  • A pre-set messages that aim to trick the victim into opening an e-mail attachment or clicking on a malicious web link.

The e-mail addresses are usually containing either a malicious e-mail attachment or a web link. Such may be presented in the text of the e-mail as a legitimate documents of important nature. These documents could pretend to be invoices or other type of files that may be dangerous to the user.

Other forms of spreading this malware may also include it’s distribution via fake setup files, fake Adobe flash player or other types of software updates, or even fake executables uploaded on torrent websites.

SecretSystem Ransomware – Malicious Activity

After SecretSystem has already infected a computer, system, the virus may firstly drop it’s malicious files. One of them is identified to be named ”Ransomeware.exe”. They may be under different names and with different locations. The usual places they may reside are the typical Windows directories:

The virus may also attach the Windows Registry Editor’s registry sub-keys, such as the:

  • Run sub-keys.
  • RunOnce sub-keys.
  • Desktop sub-keys.

The location of the sub-keys is the following:

  • HKEY_CURRENT_USER\Control Panel\
  • HKEY_USERS\.DEFAULT\Control Panel\
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion

In those keys, custom value strings with data in them may be dropped. The data points to the location of the malicious file that encrypts files so that it automatically runs on system startup.

In addition to this, SecretSystem ransomware also aims to delete backups and shadow volume copies on the infected computer. This is achievable by obtaining administrative permissions on the infected computer and executing the following administrative Windows commands:

→ process call create “cmd.exe /c
vssadmin.exe delete shadows /all /quiet
bcdedit.exe /set {default} recoveryenabled no
bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures

After this, the SecretSystem ransomware may execute an obfuscated script that puts the computer into a lockscreen that pretends to be Windows Update. This very carefully masks the restart of the victim’s computer, so that the encryption of the files can be initiated during system boot:

.slvpawned File Virus – Encryption Process

When it begins encrypting files, the SecretSystem ransomware is very careful to skip certain folders that may result in breaking your operating system, such as:

  • %Windows%
  • %AppData%
  • %Temp%
  • %Roaming%
  • %Local%
  • %LocalLow%
  • %ProgramFiles%

Besides these folders, the virus may scan in all other folders for different types of important documents, audio files, video files and many others. The way the SecretSystem detects files is by looking at their file type. It may look for the following file types:


If the file extensions match with the ones SecretSystem ransomware is configured to encrypt, it begins replacing the data of those files with data from the encryption algorithm it uses. But the good news is that only segments of data are encrypted, enough to render the files no longer openable. If there is a mistake in the coding, the files may be restored. The file extension added to the encrypted files is reported to be .slvpawned and they look like the following after an encryption takes place:

After the encryption process, naturally, the SecretSystem ransomware drops it’s ransom note with the instructions how to recover encrypted files:

All Your Files are Encrypted by SecretSystem
If you Close me you will loose all Your Files.
If you want to decrypt your files follow this simple steps:
1.) Create BitcoinWallet
2.) Buy Bitcoins worth of $500

What is SecretSystem Ransomware?

SecretSystem is a ransomware infection - the malicious software that enters your computer silently and blocks either access to the computer itself or encrypt your files. 

Many ransomware viruses use sophisticated encryption algorithms to make your files inaccessible. The goal of ransomware infections is to demand that you pay a ransom payment to get access to your files back.

What Does SecretSystem Ransomware Do?

Ransomware in general is a malicious software that is designed to block access to your computer or files until a ransom is paid.

Ransomware viruses can also damage your system, corrupt data and delete files, resulting in the permanent loss of important files.

Another way you may become a victim of SecretSystem is if you download a fake installer, crack or patch from a low reputation website or if you click on a virus link. Many users report getting a ransomware infection by downloading torrents.

How to Open .SecretSystem files?

You can't without a decryptor. At this point, the .SecretSystem files are encrypted. You can only open them once they are decrypted using a specific decryption key for the particular algorithm.
