Indrik Ransomware – Distribution Techniques

Indrik ransomware is a newly released virus that appears to have been made by the criminal collective or hacker responsible for its distribution. The available information about the made attacks shows that it is made to target all users around the world, no regional preference has been noted yet. This means that it potentially every Internet-connected computer is a possible targets.

It is very possible that several of the main ransomware delivery methods can be used at once. This is done so in order to both maximize the number of infected clients and also to find out which would be the most useful tactics.

One of the most popular is to coordinate phishing email messages that depend on two factors — the large number of sent messages and the phishing tactics that will coerce the victims into thinking that they are receiving a legitimate notification. In their body contents interactive content or text links can lead to the ransomware infection files. In other cases direct file attachments may be offered.

Another popular tactic is the creation of malicious web sites that mimic or claim to be legitimate and safe download portals, vendor sites, product landing pages and other areas from where applications can be acquired. Similar sounding domain names can be used, along with self-signed security certificates. These two steps can add a notion of legitimacy to the visitors.

Ransomware files of all families are also widely available on file-sharing networks, the most popular example is BitTorrent. The reason for this is because they are are used to promote both legitimate content and pirate data.

All of these methods can additionally offer infected payload carriers, the two most popular ones are the following:

  • Software Setup Files — The criminals can take the legitimate application installers of popular software and modify them in order to to lead to the Indrik ransomware infection. Usually popular software is chosen in order to reflect those applications which are most likely to be installed. The way they are made is by taking the original executable files and modifying them to include the necessary malicious code. They will be then be uploaded to the hacker-controlled servers or to the other delivery methods.
  • Malicious Documents — The other popular tacic is the insertion of scripts that will install the Indrik ransomware across all popular document types: spreadsheets, text documents, presentations and databases. Such files will spawn a prompt when opened asking the users to enable the built-in scripts (macros). This action will trigger the ransomware download procedure, leading to its installation.

Carrying out larger distribution campaigns may make use of browser hijackers, dangerous plugins made for the most popular web browsers. Even though they are of malicious nature when they are uploaded to their relevant plugin repositories in most cases hacker-made or stolen developer credentials will be used. They will entice the victims into installing them — performance optimizations or feature additions will be promised. However upon installation the victim users will find that their settings will changed to redirect to a set landing page. At the same time the virus will be installed alongside other possible malware threats.

Indrik Ransomware – Detailed Analysis

The Indrik ransomware does not appear to originate from any of popular malware families which gives researchers reasons to believe that it may be created entirely by the hackers or ordered through the hacker underground markets. At the moment of writing this article a detailed security analysis is not yet available however we anticipate that future versions of the threat will include a large number of modules.

The infections might begin with the launch of a data harvesting component which can hijack information that can be grouped into two main categories:

  • Victim User Information — The engine can lookup strings that may reveal data about the victim users. The information can expose their real name, address, location, interests and even stored passwords. Most advanced ransomware can also interact with the installed software and hijack information used by them, one of the popular examples is the access of web browser data.
  • Computer Information — The associated engine can lookup information related to the installed hardware components on the compromised systems. The bulk of this data collection includes additional information as well such as regional and user settings and specific operating system conditions. Together they can be used by an algorithm that will output a unique infection ID.

The collected information can be used further to initiate a security bypass which looks up if any security software or services are installed on the computers. Depending on the exact configuration the Indrik ransomware can locate and bypass (or entirely remove) antivirus software, firewalls and debug environments.

When these steps have complete the ransomware engine will have control of the machines — accessing information, hooking up to existing processes (both operating system services and applications) and creating its own processes. Modifications to the Windows Registry can cause serious performance issues, especially when strings used by Windows are modified. On the other hand changes to values used by applications can make them not run at all or terminate with unexpected errors.

A related mechanism often made by most advanced ransomware is the persistent installation — the virus engine will install the virus in such a way that will make recovery very difficult unless a professional-grade anti-spyware solution is used. This is usually done by altering boot options and configuration files which will block the usual menus used for recovery. Some viruses may also resort to the removal of System Restore points, Shadow Volume Copies and backups.

Advanced ransomware infections may also lead to the installation of Trojan Horse infections establishing a persistent connection to a hacker-controlled server. It will allow the malicious operators to take over control of the infected machines, spy on the victims and steal their data prior to the encryption phase.

Indrik Ransomware – Encryption Process

The Indrik ransomware exhibits typical ransomware behavior by using a built-in list of target file type extensions. A strong cipher is employed in order to make data recovery very difficult. Depending on the exact configuration the list may be built into the samples or downloaded upon connection to the hacker-controlled servers.

In most cases the typical lists will target the most commonly used data:

  • Archives
  • Databases
  • Backups
  • Music
  • Videos
  • Photos

All affected files will be encrypted with the .INDRIK extension. The ransomware note will be written in a file called # HOW TO DECRYPT YOUR FILES # .html which contains the following contents:

What Happened to My Files?
All your files have been encrypted using military grade encryption algorithm.
Any attempt to decrypt or recovery your files else than use will cause permanent damage to your files. This means you will lose them forever.
The only way you can decrypt your files is purchase your unique decryption tool from us.


It is not advised to use third party tools to decrypt, If we find them you, will forever lose your files.
