What is Dragon ransomware? And how does it execute its attack?

dragon randomware

Dragon ransomware is a newly-discovered variant of the Aurora ransomware which was first spotted in mid-August 2019. It uses a “.locked” extension in marking the files it encrypts. Apart from the extension it uses and its ransom note, another notable change in this new Aurora variant is the RSA 2048 cipher which it now uses in encrypting files.

The instant it executes its attack, a malicious payload is dropped in the system which activates the crypto-virus. From there, it establishes a connection to a remote Command and Control server controlled by the attackers. It may also employ an information-gathering module in order to obtain information about the infected PC and its user. The harvested data is then sent to the remote server where the ransomware downloads an additional malicious file that helps it in the execution of its attack.

These malicious files are placed in the system folder which helps the crypto-malware from being detected by any antivirus programs or security software. Some of the malicious files also modify the Windows Registry which allows the crypto-malware to run on every system boot. After all these changes are applied, Dragon ransomware will start its search for targeted files to encrypt. Once it finds them, it applies the RSA 2048 encryption algorithm in locking the files. Following data encryption, it appends the “.locked” extension to each one of the encrypted files. It also releases a ransom note named “#DECRYPT_MY_FILES#.txt” that states:

#What happened to your files?
All your files have 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 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?
1. buy 0.3 bitcoin at https://localbitcoins.com
2. contact us by email to get a payment address
3. send bitcoin to our payment address
4. after payment, we will send you Dragon Decryptor
