Dragnea Ransomware – Threat Behavior

The GUI of the Jigsaw Ransomware is used by Dragnea Ransomware for its specific purposes. The Ransom Note specifies that the user’s files will be destroyed. It has a timer of 72 hours within the ransom note. This clock indicates the amount of time a user has to pay the ransom.

The ransom note looks unfinished when compared to other ransom notes. The ransom note fails to mention a BitCoin address or a contact mail to the hacker. Here is how the ransom note translates for English speaking users on Google translate:

The Dragnea Ransomware doesn’t encrypt the user’s files but it adds a .dragnea file extension to each of the files it targets. As an example, a FileABC.doc will be represented as FileABC.doc.dragnea.

The addition of the file extension to the file format leaves the related software unable to open the file. This detail is missed by users and they feel helpless when the ransom note is displayed to them.

The Dragnea Ransomware does not come with a file encryptor program and just has a code that adds the .dragnea file extension. As it fails to encrypt the files like other Ransomware, it cannot be determined whether Dragnea Ransomware makes changes to the system registry or windows processes in the background.

The Dragnea Ransomware ransom note has a button at the bottom which should provide the decryption key to the user upon clicking. When the user clicks this button only an error message is displayed and no decryption key is provided. Future versions of the Dragnea ransomware might have the full capabilities that a ransomware program has.
