Matrix Ransomware – Distribution Tactics
The .ITLOCK Matrix ransomware variant is a new custom variant that is derived from the well-known virus family. As such we presume that the hackers are going to use the typical distribution tactics like previous iterations. As there is a fairy low number of found infections we presume that the captured samples are test versions or the initial limited release.
A typical infection will make use of phishing email messages that are designed to imitate well-known Internet sites or services that the users might use. The criminals often use templates for password reset notifications, software updates and other messages that require some kind of a user interaction. The malicious files can be directly attached or linked in the body contents.
Matrix ransomware infections can also be caused by interacting with fake download sites which are created in a similar way. They can impersonate the vendor download pages of well-known applications or use other social engineering techniques.
Matrix ransomware strains be embedded in infected payload carriers of which there are two popular types:
- Documents — There are many examples that can be used to cause infections utilizing the most common types: spreadsheets, presentations, rich text documents and databases. Upon opening them the victim user will be shown a notification box asking them to enable the built-in scripts. If this is done the macros will trigger the ransomware deployment.
- Application Installers — A similar technique is the inclusion of the virus code in hacker-modified setup files of popular software. They are distributed using the same tactics used by the hackers to solitary virus files.
Both the Matrix ransomware files and its many carrier forms can be spread on various file-sharing networks like BitTorrent. They are frequently used to distribute pirate content or image files of Linux distributions.
Large-scale infections can be caused by the upload of dangerous web browser plugins, alternatively known as hijackers or redirects. They are made compatible with the most popular web browsers and are uploaded to their respective repositories. They are accompanied by elaborate descriptions with promises of enhancing the software — adding new functionality or optimizing the already existing base. Fake user reviews and developer credentials are employed to further convince the victims into installing them. When this is done the built-in code will reconfigure the software into redirecting the users to a hacker-controlled page, the most important settings are altered: the default home page, new tabs page and search engine. Following this the virus will be deployed.
Matrix Ransomware – In-Depth Analysis
The .ITLOCK Matrix ransomware follows the typical behavior pattern used by previous versions. This means that the modular framework can be fine tuned to follow different patterns depending on the exact campaign. Usually the first module that is run afterwards is the data harvesting component. Depending on its configuration it can hijack data that can be used by the hackers to optimize the attacks — a report on the installed hardware components, user settings and operating system values. Additional information can be extracted which can be used to expose the identity of the victims by revealing their name, address, location, interests and any stored account credentials. The information may be collected and sent to the operators automatically or archived in a secure location and accessed at a later stage.
This data can then be processed by another module called stealth protection which can scan the victim system for any security software or services that can interfere with the correct virus execution. This is usually done by using signatures to scan for anti-virus engines, sandbox environments and virtual machine hosts. Their real-time engines can be bypassed or the software completely deleted.
When these two components have finished execution the Matrix ransomware the main engine will have complete control of the victim system. This leads to the ability to cause various system modifications including the following:
- Persistent Installation — The main engine can be installed in a persistent way. The results from this action are that it will be started automatically once the users power on their systems. This action can prevent certain system processes and user-installed applications from running properly. In some cases this can also prevent access to the recovery boot menu.
- Windows Registry Changes — Matrix ransomware samples may be programmed to modify the Windows Registry entries belonging both to user-installed applications and the operating system itself. This can cause a significant drop in performance and make the infected systems very unstable. Certain services or functions can become unusable.
- Files Manipulation — One of the most common consequences of having a Matrix ransomware infections is the deletion of Shadow Volume Copies and Restore Points which makes recovery more difficult.
If configured so some Matrix ranasomware can lead to a Trojan infection. The default behavior is for the malicious engine to download and execute a client instance. It will set up a secure connection to a hacker-controlled server. It allows the hacker operators to take over control of the infected victims, steal their files and spy on the victims.
Other modules can be added as desired depending on the hacker configuration.
Matrix Ransomware – Encryption Process
Matrix ransomware strains engage in the typical encryption behavior. It will process user data according to a built-in list of target file type extensions. An example list can target the following file types:
As a result all victim files will be renamed with the .ITLOCK extension. A generic ransomware note will be created in a file called !ITLOCK_README!.rtf which will blackmail the victims into paying the criminals a fee for “restoring their files”. In reality they will ignore the infected hosts and just take the money.
Advanced versions can also lead to a deployment of a lockscreen which will actively block the ability to use the computer until the infection is completely removed.
Remove Matrix Ransomware and Restore .ITLOCK Files
