In this article, you will find more information about Dragon ransomware as well as a step-by-step guide on how to remove malicious files from the infected system and how to recover .locked files.
Dragon ransomware is a vicious cryptovirus that corrupts computer systems and personal files to extort ransom payment from victims. As identified by security researchers Dragon ransomware is based on the code of another ransomware dubbed [wplinkpreview url=”https://sensorstechforum.com/remove-aurora-ransomware-virus/”] Aurora. Since the threat corrupts target files by utilizing the strong RSA-2048 encryption algorithm, it leaves them completely inaccessible. Dragon ransomware also adds the .locked file suffix and drops a ransom note file. The note is dropped on the system as a file called #DECRYPT_MY_FILES#.txt and it aims to blackmail you into paying a hefty ransom fee to hackers.

Dragon Ransomware – Spreading and Description
The most probable attack vector used for the spread of Dragon ransomware is malspam. Malspam is a preferred technique as it enables hackers to deliver malicious code on users’ devices with the help of massive email campaigns. Spam emails which are part of attack campaigns usually contain one or more of the following components:
- A link to compromised web page that is set to download and execute infection files directly on the PC. The URL address to this page may be presented as an in-text link, banner, image, button or full URL address.
- A malicious file attachment that is presented as legitimate document by the text message. It could be uploaded in a .rar or .zip archive. Such a file could be set to evade active security measures and trick you into running the ransomware on your PC.
Other channels that may be part of the distribution strategy for Dragon ransomware are malvertising, freeware installers, corrupted web pages, compromised software setups, fake software updates, malicious files shared on forums and other.
The moment Dragon’s payload starts on the system, the ransomware begins the attack. During the attack, Dragon ransomware completes various malicious operations. As a result, the threat becomes able to remain undetected while corrupting target personal files.
For the encryption stage, Dragon ransomware activates a built-in cipher module. This module scans predefined system drives for target types of files to modify their code with the RSA-2048 cipher algorithm. Once the encryption process is done you cannot access the data stored by valuable files like:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
Following encryption, corrupted files could be recognized by the extension .locked which is appended to their names.
Once Dragon ransomware is ready with the encryption process it drops a ransom note file to extort a hefty ransom fee for .locked files decryption tool. The note could be found in a file called #DECRYPT_MY_FILES#.txt and all that it reads is:

############################What happened to your files?
All your files has been encrypted by a strong encryption with RSA-2048.
More information about the encryption keys using RSA-2048 can be found here: https://en.wikipedia.org/wiki/RSA_(cryptosystem)#What does this mean?
This means that the structure and data within your files have been irrevocably changed, you will not be able to work with them, read them or see them, it is the same thing as losing them forever, but with our help, you can restore them.#How did this happen?
Especially for you, on our server was generated the secret key pair RSA-2048 – public and private. All your files were encrypted with the public key, which has been transferred to your computer via the Internet. Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our secret server.#What do I do?
Alas, if you do not take the necessary measures for the specified time then the conditions for obtaining the private key will be changed. If you really value your data, then we suggest you do not waste valuable time searching for the solutions because they do not exist.
Trying to reinstall the system and decrypting the file with a third-party tool will result in file corruption which means no one can decrypt your file(including us)!
If you still try to decrypt the file yourself, you do so at your own risk!#Test decryption!
As a proof, you can send 3 encrypted files and ID to test decrypt,and we will send you the decrypted files to prove that we can decrypt your files.
To decrypt all your files, you need to buy Dragon Decryptor.#How to buy Dragon Decryptor?

How to Remove Dragon ransomware from Windows.
Step 1: Boot Your PC In Safe Mode to isolate and remove Dragon ransomware
Step 2: Uninstall Dragon ransomware and related software 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 uninstall most programs.
Step 3: Clean any registries, created by Dragon ransomware 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 Dragon ransomware 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.
