Java (Dcrtr Variant) Ransomware – Distribution Techniques

The Java (Dcrtr variant) ransomware uses various techniques to distribute itself to users’ computer devices. A payload dropper which initiates the malicious script for this ransomware might be spread around the Internet in different forms. You can check them in the below image:

As you can see, websites might generate advertisements which are malicious in nature and will eventually deliver the ransomware to your computer. Other websites could be compromised, and redirect you to specific domains once you are detected as a potential victim which will lead to a malicious URL that will download the payload from a server directly to your machine and quickly infect it. Other techniques might include malvertising campaigns sending fake invoices to email addresses of users, and the payload file being delivered with legitimate programs or executables.

That is why you should 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 located at the corresponding forum thread.

Java (Dcrtr Variant) Ransomware – Technical Data

Java (Dcrtr variant) is part of the ransomware family of .dcrtr Files Virus. It is a virus that encrypts your files and opens a ransom note, with instructions inside it, about the compromised computer machine. The extortionists want you to pay a ransom fee for the alleged restoration of your files.

Java (Dcrtr variant) 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 start the virus automatically with each boot of the Windows Operating System.

After encryption the Java (Dcrtr variant) virus shows the following ransom message inside a text file called ReadMe_Decryptor.txt:

The ransom message has the following contents:

All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail

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

Free decryption as guarantee
Before paying you can send us up to 3 files for free decryption. The total size of files must be less than 5 Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)

The note of the Java (Dcrtr variant) ransomware virus states that your files are encrypted. You are demanded to pay a ransom fee to allegedly restore your files. However, you should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that. Adding to that, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal activities. That may even result to you getting your files encrypted all over again after payment.

Java (Dcrtr Variant) Ransomware – Encryption Process

The encryption process of the Java (Dcrtr variant) ransomware rather simple – every file that gets encrypted will become simply unusable. Files will get the .java extension after being locked. The newly added extension will be added as a secondary one, without changing the original, nor the file name.

A list with the targeted extensions of files which are sought to get encrypted is currently unknown. However, if the list becomes available, the article will get updated accordingly.

The files used most by users and which are probably encrypted are from the following categories:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc

The Java (Dcrtr variant) 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 effects of the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data.
