Djvur Ransomware – Decryptor Released

Recently a series of new STOP ransomware variants have been released in active attack campaigns. As revealed by security experts, the main difference between newly discovered strains is the extension they use to mark corrupted files. Here you could see a list of all other extensions that testify for infection with a strain of STOP ransomware:

Happily, security experts have managed to crack the code of almost all variants of this ransomware family and released a decryption tool. So at this point only victims of .puma, .pumax and .pumas, .djvu, .djvuq, .djvur, .djvut, .djvuu, .pdff, .tfude, .tfudeq, .tro, .udjvu, .tfudet STOP ransomware versions are able to decrypt their files with the help of the decryption tool created by the security researchers AfshinZlfgh and Michael Gillespie.

In case that you are victim of one of these versions you can download it via the Decryption Tool link. The tool requires a pair of an original file and its encrypted version.

Djvur Ransomware – Distribution Ways

The Djvur ransomware as one of the strains of the STOP malware family can be acquired using the popular techniques associated with the criminal collectives behind the campaigns. One of the most efficient ways to infect victims is to send out phishing SPAM messages, they are sent in bulk and aim to coerce the recipients into thinking that they have received a legitimate message from a company, product or service that they use. In many cases the hackers will use design elements and contents from real messages when designing the fake notifications.

An alternative is to create phishing web pages which can mimic both the landing pages of services and products, as well as download pages and redirects. They are frequently placed in hacker-controlled sites and one of the primary payloads delivered by browser hijackers — malicious web browser plugins that are frequently found on the repositories with fake user reviews and developer credentials.

To make delivery more efficient the hackers can embed the necessary code into payload carriers that are widely used to infect the targets. A popular choice is the creation of documents of all popular types (databases, spreadsheets, text files and presentations). When they are opened by the users a prompt will appear asking them to enable the built-in scripts. This will trigger the Djvur ransomware infection. The other popular carrier is the application installer. The criminals will take popular software that is often downloaded by end users and modify them with the necesary code.

All Djvur ransomware virus files can additionally be spread on file-sharing networks like BitTorrent which are popular when distributing both pirate and legitimate content.

Djvur Ransomware – In-Depth Overview

The Djvur ransomware as an example of the STOP ransomware family will behave according to the built-in instructions made by the criminals. The code analysis shows that it contains much of the same code as the previous versions of the malware family. It is believed that when an infection strikes some of the common actions will be undertaken by the engine. Some of them include the following:

  • Information Gathering — The Djvur virus engine has the ability to hijack information from the machine that includes personal information about the victim user and the computer itself. It allows the criminals to carry out crimes such as financial abuse and identity theft using the harvested information. It can include both information about the installed hardware components and the set regional settings and information about the users. The engine is usually configured to extract specific data about the users: their name, address, phone number, location and even stored account credentials.
  • Persistent Installation — The Djvur ransomware virus can be installed in a way which makes it very difficult to remove. It will set itself to automatically start when the computer is powered on and can reconfigure important system files, Windows Registry values and boot options.
  • Windows Registry Changes — As a strain of the Stop ransomware family the Djvur virus can also be programmed to create and edit the existing values on the compromised computers. This can lead to the disabling of anti-virus programs, firewalls and other security software. Modifications to system related values can lead to serious stability problems, while changes to individual applications and services can cause them to quit with unexpected errors.

Depending on the individual hacker configurations other behavior can also be implemented.

Djvur Ransomware – Encryption Process

What is known for the encryption process of the Djvur ransomware is that every file that gets encrypted will receive the .djvur extension. The encryption algorithms used to lock the files are AES and RSA 1024-bit.

The targeted extensions of files which are sought to get encrypted are currently unknown and if a list is discovered, it will be posted here as the article gets updated. 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 Djvur cryptovirus could be set to erase all the Djvur Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete Djvur /all /Quiet

In case the above-stated command is executed that will make the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data. If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore your files back to normal.
