Retis Ransomware – Delivery Methods
Retis ransomware might 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 system will become infected. You can see the detections of such a file on the VirusTotal service right down here:
Retis 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 the forum section.
Retis Ransomware – Detailed Analysis
Retis is a virus that encrypts your files and extorts you to pay a ransom to supposedly recover them. The extortionists want you to pay a ransom sum for the alleged restoration of your files.
Retis 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.
That ransom note message is displayed after the encryption of your files is complete. It is made into an image file called RANSOM.png and also put as your Desktop Background. You can view it from the following screenshot below:
The ransom note states the following:
Votre bureau, vos photos, vos données et autres dossiers importants ont été chiffrés avec un algorithme fort et une clé unique générés pour cet ordinateur.
La clé secrète pour déchiffrer vos données est gardée sur un serveur d’Internet, et personne ne peut déchiffrer vos fichiers jusqu’à ce que vous payez pour l’obtenir.
Vous disposez d’un délai de 24 heures pour nous transmettre le paiement.
PASSÉ CE DÉLAI VOTRE CLÉ SERA SUPPRIMÉE OE NOS SERVEURS ET IL NE SERA PLUS POSSIBLE POUR VOUS OE RÉCUPÉRER VOS DONNÉES
A rough translation in English looks like this:
Your desktop, photos, data and other important files have been encrypted with a strong algorithm and a unique key generated for this computer.
The secret key to decrypt your data is kept on an Internet server, and no one can decipher your files until you pay to get it.
You have 24 hours to send us the payment.
PAST THIS TIME YOUR KEY WILL BE ABOLISHED BY OUR SERVERS AND IT WILL NOT BE POSSIBLE FOR YOU TO RECOVER YOUR DATA
The note of the Retis ransomware states that your files are encrypted. The ransom sum demanded as payment is unknown. Even if you somehow acquire an email to contact the crooks, you should NOT under any circumstances pay any ransom. Your files may not get recovered, and nobody could give you a guarantee for that. Moreover, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal activities.
Retis Ransomware – Encryption Process
What is known for the encryption process of the Retis ransomware is that every file that gets encrypted will receive the .Crypted extension. Some malware researcher sat that the ransomware encrypts files with the AES encryption algorithm, while others oppose that claim.
The targeted extensions of files which are sought to get encrypted are listed right down here:
→.doc, .docx, .jpeg, .jpg, .one, .pdf, .png, .ppt, .pptx, .txt, .xls, .xlsx
The Retis cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
In case the above-stated command is executed that will make the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore 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 restore your files back to normal.
Remove Retis Ransomware and Restore .Crypted Files

- Step 1
- Step 2
- Step 3
- Step 4
- Step 5
Step 1: Scan for Retis with SpyHunter Anti-Malware Tool
Ransomware Automatic Removal - Video Guide
Step 2: Uninstall Retis and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Retis on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Retis there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Retis
Step 5: Try to Restore Files Encrypted by Retis.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
2. Agree with the license terms:
3. Click on "Add Folder" and then add the folders where you want files decrypted as shown underneath:
4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and Retis aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
