Distribution of .SERVER Virus

The .SERVER Virus is a new virus which has been sighted in attack campaign. At the moment the security researchers cannot determine the primary infection strategy. We presume that the most widely used tactics are going to be employed.

Among them are the email messages created in an automated way and sent to large lists of potential victims. The .SERVER Virus can be directly attached to the messages. This is one of the easiest way for the criminals to attempt the infection. However a lot of email hosting providers usually capture the signatures of the virus and as such discard such messages or label them as dangerous or spam. Other infection methods related to this one is the option of inserting hyperlinks in the body content of the messages. The links are usually labelled as leading to a familiar website or a file of user interest. Redirects can redirect to hacker-controlled sites, infected payloads or other instances that can lead to an .SERVER Virus infection.

The computer criminals behind the malware can create malicious sites or download portals which distribute malware of different kinds, including the .SERVER Virus. A popular option is the use of infected documents which may be of different types ‒ spreadsheets, rich text documents, presentations and databases. They are modified to initiate the virus once the built-in scripts are run. Usually when the files are opened a notification will ask the users to run the macros (scripts). If this is done the infection follows.

The hacker-controlled sites are specialist portals that have been created either manually or automatically by the criminals behind the .SERVER Virus. They can either directly distribute the threat by initiating various scripts or automated operations or link to such instances. Redirects are usually caused by email interaction, ad networks or other browsing activity. However one of the main sources is the availability of browser hijackers. They are malicious addons made for the most popular web browsers ‒ Mozilla Firefox, Google Chrome, Internet Explorer, Opera, Microsoft Edge and Safari. Once installed they not only infect the users with the malware, but also redirect the victims to a hacker-controlled site. Depending on the configuration the browser hijackers can also steal sensitive information such as any stored passwords, account credentials, history, bookmarks, form data and settings.

Impact of .SERVER Virus

Cryptomix ransomware viruses continue to be produced by hackers. The latest strain of this malware family is the .SERVER virus which is made by an unknown individual or criminal collective.

The code analysis reveals that it follows the same behavior patterns as previous samples belonging to Cryptomix. The researchers note that few customizations have been made in comparison with already known infections. As usual the infections are carried out in several stages. The first one is always related to the system modifications that take place:

    Boot Options — The .SERVER virus disables the startup repair option and boot recovery options that are used by the victims to attempt to remove the virus infections.
  • Data Changes — All system modifications related to files are categorized in this part of the attack behavior. Examples include the deletion of the Shadow volume information and important configuration files. As a consequence the victims need to use a professional-grade data recovery solution.
  • Information Gathering — The .SERVER virus has the ability to extract a lot of sensitive data from the victim machines. This includes not only the operating system itself, but also user applications. Web browsers are a often given example as the hackers can retrieve all stored data. This includes history, bookmarks, settings, site preferences, cookies, accounts and passwords.
  • Operating System Changes — They often include tactics such as services shut down, registry changes and other related modifications. As a consequence the victims might face performance issues or notice that certain applications and services may stop working.

CryptoMix ransomware strains such as the .SERVER virus are known to contact hacker servers. This is a popular tactic used to cause additional damage to the hosts. In certain situations they can lead to a Trojan infection. It allows the hacker controllers to take over control of the victim machines at any given time.

Other dangerous behavior includes the ability to institute browser hijackers. This is possible by either modifying the settings of the web browsers or delivering additional executable files or extensions. The web browser’s settings can be altered in a way which actively transmits the network traffic through the hacker-controlled servers. As a result the criminal operators can spy on the users actions in real time without resorting to the use of a Trojan component.

Once all prerequisite conditions have been met the .SERVER Virus starts the ransomware component. Like previous versions of the CryptoMix ransomware family it uses a built-in list of target file type extensions. Usually they represent the most popular data: archives, documents, backups, images, videos, music, databases and etc. Consequently all victim data is renamed with the .SERVER extension. The ransomware note itself is created in a _HELP_INSTRUCTION.TXT file that reads the following:

Hello!

IMPORTANT: DO NOT USE ANY PUBLIC SOFTWARE! IT MAY DAMAGE YOUR DATA FOREVER!
DECRYPT-ID-[id] number

The analysts detect that all malware samples assign a unique victim ID that is generated by the engine. The ID numbers are used by the attackers to discover the number of infected hosts. In some cases they can be used in a large-scale botnet attack.
