Satyr ransomware. How to remove? (Uninstall guide)

removal by Gabriel E. Hall - - | Type: Ransomware

Satyr ransomware is a new cyberthreat discovered by security experts in April

Satyr ransomware

Satyr ransomware is a crypto-virus that encrypts all user files using AES[1] and RSA-2048 encryption algorithm and appends .Satyr appendix to each of the files. This process makes data unusable, and until the ransom of 0.018 BTC is paid, the hackers will not disclose decryption key to the victim. The virus uses the same file – SF.exe – as Spartacus ransomware.

SUMMARY
Name Satyr ransomware
Type File locking virus
Extension .Satyr
Cipher used AES and RSA-2048
Ransom size 0.018 BTC
Contact https://t.me/tony_montana10928 or @tony_montana10928
Distribution Spam emails, infected installers, malicious links, etc.
Elimination Download and install Reimage or Plumbytes Anti-MalwareNorton Internet Security

The malware enters users’ machines through malicious sites, links, infected downloads or spam emails. However, ransomware does not instantaneously lock up files. First, Satyr virus executes a chain of specific changes to system configuration to ensure that the malicious program loads with every computer boot up.

Then, the crypto-locker scans the computer for files (it can be any personal files, like video, music, PDF, text and other) that can be encrypted and executes the process by appending .Satyr extension. For example, the file that used to be called picture.jpg turns into picture.jpg.Satyr.

The virus also typically protects itself by disabling security software. Thus, users are recommended entering Safe Mode with Networking. From there, users should start up a reliable security tool (such as Reimage, Malwarebytes or Plumbytes Anti-MalwareNorton Internet Security) and then proceed with Satyr removal.

As soon as ransomware completes its data encryption process, it drops a ransom note that explains to the user what happened:

Security tips

All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us the Telegram: https://t.me/tony_montana10928 or @tony_montana10928 and send personal ID KEY: <…>

For Decrypt Your Personal Files Send 0.018 BTC to this address: <…>

You have to pay for decryption in Bitcoins. The price depends on how you write us. After payment we will send you decryption tool that will decrypt all your files

As evident, Satyr authors want victims to contact them via Telegram messenger after the payment of 0.018 BTC (around $147.5 at the time of writing) is processed. However, we do not recommend contacting hackers.

Cybercrooks are promising to send the decryption tool, but nobody guarantees that the file is not malware. This way, you could compromise your computer even more. What is more, if you show that ransom demands can be successful, hackers will create more viruses to extract more money out of innocent users.

Instead, you should remove Satyr ransomware and then proceed with file recovery procedure. Unfortunately, the only secure way to get data back is by recovering it for a remote server – like iCloud or Google Drive or from an external storage device. If you do not possess any back-ups, you can try alternative file recovery methods which we describe below this article.

Be careful when opening emails as they can contain the deadly ransomware payload

Security researchers[2] noted that the most prevalent ransomware distribution method is via spam emails. Thus, users should be careful when handling new emails coming from unknown sources:

  • Do not open emails carelessly, even if they seem legitimate;
  • Do not open any attachments in the email. The contaminated file typically asks to enable macro function;[3]
  • Do not ignore the built-in security software warnings about phishing emails;
  • Check the address the email was sent from to make sure it is legitimate;
  • Do not click on any links inside the email. Keep in mind that hyperlinks enable hackers to disguise a malicious site inside the link.

Another dangerous place on the internet is all suspicious websites, including illegal software, pornographic, free online gaming, gambling and similar high-risk sites. Thus, stay away from them and close your browser if you get redirected.

Remove Satyr ransomware and recover your files

Ransomware infection is a serious threat and should not be taken lightly. Thus, do not try to remove Satyr virus manually. Not only you will fail to get rid of the malware but might also damage system files beyond repair.

Therefore, you should download and install reputable anti-malware software and start it in the Safe Mode with Networking. Then, scan your computer for full Satyr removal.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Satyr from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

Even if the ransom demand is relatively small, we do not believe that people should be robbed by cybercriminals at all. Therefore, do not agree to pay and rather try these alternative file recovery methods we provide below.

If your files are encrypted by Satyr, you can use several methods to restore them:

Data Recovery Pro might be used to get your files back

Data Recovery Pro is a tool that was created to restore damaged or accidentally deleted files. However, it is known to help users who's files have been affected by ransomware.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Satyr ransomware;
  • Restore them.

Try Windows Previous Versions feature

Windows Previous Versions feature can be only used when the System Restore function was enabled before the infection occurred.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer might be the savior

Some ransomware viruses fail to delete Shadow Volume copies within Windows OS. If that is the case, ShadowExplorer will help you.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.
