CryptoDark Ransomware – Ways of Delivery

CryptoDark 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. A sample has been spotted by malware researchers and you can preview its analysis available on the VirusTotal service from down here:

The CryptoDark 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.

CryptoDark Ransomware – Detailed Description

The CryptoDark ransomware is a cryptovirus, which has been recently discovered by malware researchers. They believe the ransomware could be intended as some sort of a joke as the current variant does not encrypt files. Still, the malware demands a ransom payment and is portrayed as a real ransomware virus. CryptoDark ransomware will pop up a window that serves as a ransom note with instructions, whether or not it encrypts your files.

In the future, the CryptoDark 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 load up as a screenlocking image and it can be seen in the below image:

The following message with instructions states::

Your files have been encrypted!
All of your pictures, images and documents have been encrypted by CryptoDark.
To get them back, you will need to open the CryptoDark Decryptor and pay $300 worth of Bitcoin to the address shown in the decryptor.
If your anti-virus detected the decryptor, remove it from the guarantine or download a new one from:
https://www.vhyifaiuevwni.tk/CDD

By browsing your Desktop you will find the CryptoDark Decryptor which looks like the following:

and by clicking on Decrypt on it, a smaller window will pop up as shown here:

The actual ransom payment instructions portrayed in that Decryptor program and these instructions read the following:

CryptoDark Decryptor

Your files have been encrypted!

To recover your files you will need to send $300 worth of Bitcoin to this address:

WW91lGhhdmUganVzdCB3YXN0ZWQgeW91ciB0aW1lLg==

If you do not know how to get Bitcoin then click the Local Bitcoins button,

Once you have paid. you will be given a key
Click the Decrypt button and enter the key. If it is correct, your files will be
decrypted.
If you are sure you have typed the key correctly and you are still unable to decrypt
your files, come back tomorrow and it should work.

The ransom sum that is demanded as payment for allegedly restoring your files is of 300 US dollars. As the virus could be still in-development, the note can change in the future. You should NOT in any case consider paying these cybercriminals. By paying, you can motivate them to indulge in similar criminal acts in the future, and is strongly advised against.

CryptoDark Ransomware – Encryption Process

There is no official list with file extensions that the CryptoDark ransomware seeks to encrypt and the article will be updated if there are changes regarding the matter. Encryption doesn’t seem to be working for many variants of the ransomware. The virus might still be in-development.

The CryptoDark 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. Continue reading to find out what methods you can try out to potentially restore some of your files.
