.dutan Ransomware – Remove It and Decrypt Files

.dutan Ransomware virus remove

The .dutan ransomware is a dangerous new virus threat which has been confirmed to be a new release of the STOP family of viruses. It is probably being released by a new criminal collective which has probably ordered the customization on the dark underground markets. As it is based on an already known base engine we anticipate that the made changes will not differ so much from other samples of the same family.

In order for the .dutan ransomware samples to be spread against the intended victims the most popular hacking tactics will be used. One of them depends upon the coordination of large-scale phishing email messages which are sent in bulk. They pose as legitimate notifications that have been sent in by well-known services and may include attached files or scripts that when interacted with will lead to the relevant infection.

A similar mechanism is the creation of malware sites which are hosted on domain names that sound similar to well-known pages: download portals, search engines and landing pages. To make them appear as more legitimate they will include self-signed or stolen security certificates.

The virus infections can also be caused via the inclusion of the relevant code in payload carriers — dangerous files that host the malware installation code. This can be acquired through the interaction with malware documents including databases, presentations, spreadsheets and text documents. Likewise a similar strategy is used with application installers — popular end-user software setup files will be created by the hackers. When they are opened alongside the applications the .dutan ransomware will also be deployed.

Note that browser hijackers are also widely used to spread threats. They are uploaded using fake user reviews and developer credentials to the relevant repositories of the most famous web browsers.

As soon as the infection is made a series of dangerous actions will follow. They can run as part of the typical execution plan of the virus threat or they can be set individually depending on local conditions. All of this depends on the exact instructions that have been set in by the criminals. Usually the most common components that are run include the following:

  • Data Information Gathering — The engine can be used to acquire sensitive information both about the users and the infected machines. When the information is acquired by this component it can be used for various crimes such as financial abuse and identity theft. The machine information can be used by a built-in algorithm in order to create an unique signature for each affected computer.
  • Security Bypass — This is often the next module that is run in the sequence. It will use the hijacked information in order to search for any applications that may block the proper malicious infection. Usually this includes common threats such as anti-virus programs, firewalls, virtual machines and sandbox environments.
  • System Changes — Dangerous modifications to the computers can take place including boot modifications. This means that the relevant engine will be launched as soon as the computer is powered on. In addition it can also lead to Windows Registry changes — new strings can be created for the .dutan ransomware and already existing ones can be modified. This usually leads to performance issues, data loss and unexpected errors.
  • Further Malware Delivery — The made infections can be used to deploy other threats to the infected machines. Popular choices include miners, Trojans and hijackers.

When all modules have finished running the actual file encryption will start. A s strong cipher will be used to affect target user data, in most cases the most common extensions will be processed: images, music, videos, documents, databases, archives and etc. All of them will be renamed with the associated .dutan extension. A companion ransomware note will be created in order to coerce the victims to pay the hackers a decryption fee.
