Ogre Ransomware – Delivery Ways
Ogre ransomware could be delivered in more than one way. However, the way that is the most widespread is via a payload dropper file which initiates the malicious script for the ransomware. Samples have been spotted by malware researchers and you can preview one of them sent for analysis on the VirusTotal service right here:
The Ogre ransomware might be using other ways to deliver the payload file, such as social media and file-sharing sites. Freeware applications found on the Internet could be promoted as helpful but also could hide the malicious script for this virus. Before opening any files after you have downloaded them, you should instead scan them with a security program. Especially if they come from suspicious places, such as emails or links. Also, don’t forget to check the size and signatures of such files for anything that seems out of place. You should read the ransomware prevention tips given in the forum section.
Ogre Ransomware – In-Depth Overview
The Ogre ransomware is a cryptovirus, which has been recently discovered by malware researchers. They believe that the ransomware is still in-development. When the Ogre ransomware encrypts your files, it will put the .ogre extension to every file and show a window that serves as a ransom note with instructions.
In the future, the Ogre ransomware could be set to make new registry entries in the Windows Registry to achieve a higher level of persistence. Those entries are usually designed in a way that will start the virus automatically with every launch of the Windows Operating System, like in the example given below:
→“HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run”
The ransom message will be placed inside a window which might have a screen-locking capability. That message is shown in the below image:
The following message about the ransom payment is in that window:
Ogre RansomWare
Your files have been encrypted.
The only way to recover them is to send 20€ in bitcoin to this adress.
(Programme test)
Note: Critical files have been encrypted.
If you stop your computer, there are high chance your computer will be unusable for ever.
Enter your bitcoin adress used to pay
Decrypt
Check payment
The ransom sum that is demanded as payment for allegedly restoring your files is currently 20 euros. That ransom can always change and as the virus is still in-development, the note can change, as well. No matter what sum of money is asked from you, you shouldn’t in any case consider paying the cybercriminals. Paying those crooks can motivate them to indulge in similar criminal acts in the future, and is strongly advised against.
Ogre Ransomware – Encryption Process
There is no official list with file extensions that the Ogre ransomware seeks to encrypt and the article will be duly updated if such a list is found. However, all files which get encrypted will receive the .Ogre extension appended to them. The encryption algorithm is currently unknown.
The Ogre cryptovirus is more than likely to erase the Shadow Volume Copies from the Windows Operating System by executing the following command:
→vssadmin.exe delete shadows /all /Quiet
If the above-stated command is inputted into the command prompt of the Windows operating system, that will make the encryption process more effective, as one of the main ways for file recovery will be gone. Keep reading to find out what methods you can try out to potentially restore some of your files.

Step 2: Uninstall Ogre 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 Ogre 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 Ogre 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 Ogre
Step 5: Try to Restore Files Encrypted by Ogre.
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 Ogre 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.
