Vurten Virus – Infection Spread
The Vurten virus can be distributed using various methods depending on the end targets. The hackers can optimize the malware delivery by using the most appropriate strategy for the desired scale of attacks.
A common way is to create spam messages that utilize various social engineering techniques in order to blackmail targets. The criminals can opt to use malware hyperlinks that link to the Vurten virus files hosted on hacker sites. Usually the criminals take text and graphics from well-known Internet services and sites. The messages are customized in order to appear as being sent by the companies rather than computer criminals. Another strategy would be to directly attach files to them.
The Vurten virus can be embedded in various payloads that are widely available through various sources. Usually the two most common ways are the following:
- Infected Installers — The Vurten virus can be inserted into software installers that have been taken from their official vendor sites. Usually the criminals target popular instances such as creativity apps, system utilities and games.
- Malware Documents — The hackers behind the Vurtue virus can embed the malware code into files of different types: presentations, spreadsheets and rich text documents. Once the recipients open the associated files they will be greeted by a notification prompt which asks them to enable the built-in scripts. If this is done then the virus will be downloaded from a remote location and executed on the compromised machine.
The criminals can make use of another method that has become popular in the last few years — browser hijackers. They represent malware browser plugins that are usually distributed on the plugin repositories operated by the major browsers. The instances are listed using elaborate descriptions and counterfeit developer credentials and user reviews. They are usually made compatible with the most popular web browsers: Mozilla Firefox, Google Chrome, Microsoft Edge, Opera, Safari and Internet Explorer.
Vurten Virus – Technical Data
The security analysis of the Vurten virus does not reveal a correlation with any of the known malware families. At the moment the full analysis is not yet complete and the captured samples contain only basic functionality. It is possible that the threat is still in development or preliminary testing before being released once again.
Future versions of it can include various additional components. An example is an information gathering which can be started once the malware has infiltrated the systems. It is programmed to extract data of different kinds from computers. It is usually classified into these two groups:
- Personal Data — It is composed of information that can directly expose the victims identity. Their name, address, interests, location, account credentials and passwords.
- System Data — This type of data usually consists of information related to the installed hardware components and certain operating system and software configuration files.
The gathered information can then be used for analysis and stealth protection. By analyzing the harvested data the Vurten virus can counter applications that can interfere with its execution. Examples include anti-virus software, virtual machine hosts and sandbox environments. If any of them are found their engines can be stopped or the application may altogether be removed. In advanced cases the malware strains can be programmed into deleting themselves to avoid detection.
Further updates to the base version of Vurten virus may include a variety of different system modifications. An example one is the removal of the recovery menu. This is the result of boot menu options manipulation which prohibits the users from using this manual recovery method. Another issue is the modification of the Windows Registry which can result in application failure and overall system stability issues. If the virus impacts any system services, they might be rendered partially non-working or even disabled.
Some malware also have the ability to institute a permanent network connection to a hacker-controlled server. It can be used to gather the harvested data and send arbitrary commands to the infected hosts. An interesting proposition is the remote control capabilities that are very similar to standalone Trojans.
Vurten Virus — Encryption Process
Once all malware components of the Vurten virus have executed correctly the ransomware module is launched. Like other similar threats it uses a built-in list of target file type extensions. Typically it seeks to target the following data:
The following extensions are being targeted (taken from a recent malware sample):

.wdb, .wim, .win, .wks, .wrk, .xld, .xlk, .xls, .xlsm, .xlsx, .xml, .xps, .zip
All target data is renamed with the .improved extension. The malware engine uses a strong cipher that encrypts the user files. It can only be recovered by first removing the virus.
A ransomware note is created in a file called UNCRYPT.README.txt which contains the following message:
Your entire network sensetive data was encrypted with our strong algorithm.
To recover your data send $10000 to the bitcoin address: 1Ln9RxSRuDqqFhCTuqBPBKRMeyhVhRaUG4
If you do not send money within 7 days, payment will be increased double.
After payment you will receive decryption software.
