Distribution of .TEST virus

The .TEST virus is a new virus which has been sighted in a limited 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 .TEST 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 labeled 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 .TEST virus infection.

The computer criminals behind the malware can create malicious sites or download portals which distribute malware of different kinds, including the .TEST 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 .TEST 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 .TEST virus

The CryptoMix ransomware family has gained a new member as security researchers uncovered a new strain called the .TEST virus. It features some built-in counterfeit identities which aim to confuse the users or the security software. The executable files that carry the threat may be named as frtan.exe and include includes copyright stating that the file comes frm the Alibaba Group.

The .test virus has been found to initiate a complex behavior pattern as soon as the infection has been instituted on the target computer. Depending on the hacker configuration and target users the malware samples can perform different dangerous alterations to the hosts. The captured samples have been fount to cause a lot of changes related to the way the computer boots and works in order to protect the dangerous code from manual removal methods.

Some malware samples have been found to extract sensitive information from the infected host, several categories can be identified:

  • System Information — The .test virus is able to collect information about the available hardware components, installed software and user configuration.
  • Language Settings — The .test virus has the ability to extract all settings and user set values that are related to the regional and language settings. The data allows the hackers to locate the user and their individual preferences. Based on their language of choice a respective message or ransomware note can be shown.
  • Personally-identifiable Information — The infection engine harvests information from the browsers and applications such as accounts, passwords, preferences, bookmarks, history and etc.

The .test virus has been found to disable certain Windows functionality including services, the Windows registry and etc. The security experts note that boot-up options are also being changed. Data recovery is obstructed by the .test virus infection engine as it deletes the shadow volume copies of all found data.

The ransomware engine is started when all prior steps have been taken. Like previous samples that originate from this malware family it uses a built-in list of target file type extensions. Examples include the following: documents, archives, music, videos, image, databases, backups and configuration files. All processed files are not only renamed with the .test extension, but also have their names obfuscated with a random 32-character-long ID.

The ransomware note itself is created in a _HELP_INSTRUCTION.TXT file which contains the following text:
