Distribution of .enc Virus

The .enc 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 .enc 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 .enc Virus infection.

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

Recent malware infections with a threat called the .ec virus has caused a major security investigation. Victims of this threat should know that this is the alternative name of the MadBit ransomware. The initial code analysis made upon the collected samples shows that it does not derive from any of the famous ransomware families. And no information is available about the hacker or criminal collective behind it.

At the moment the captured samples of the .enc virus showcase a modular framework that allows the threat to be further extended in future versions. The captured samples can be updated to execute a complex behavior pattern. Such infections begin by extracting sensitive information from the compromised hosts. Usually advanced strains generate a complete profile of the hardware components. The values are usually entered as input parameters when generating the unique victim ID. The security and privacy risks associated with such infections are related to the fact that the .enc virus can also include code that harvests sensitive user credentials. They can be extracted both from the operating system itself or the installed user applications. Usually the most popular software are targeted, popular examples are the most widely used web browsers including: Mozilla Firefox, Google Chrome, Microsoft Edge, Safari and Internet Explorer. The hackers can access the stored data such as the: bookmarks, cookies, history, autofill information, passwords and account credentials.

The next step would be to prevent security software from detecting and deleting the threat. Using the obtained information the availability of any sandboxes, virtual machines and debug environments can be countered. If the virus finds that it cannot delete or overcome the security software then it can delete itself to avoid detection.

Once all of this is done the actual infection process can continue. One or two stages can be organized depending on the complexity and the configuration set by the attackers.

Usually the first stage is reserved for the primary computer alterations. They can include any of the following components:

  • Windows Registry — Changes to existing registry values can result in many detrimental effects upon the compromised hosts. Depending on the made changes the users may find that certain components will cease to function properly, in other cases performance issues are faced.
  • Startup and Boot Options — The .enc virus can alter the boot options which disables the startup recovery, advanced boot options and other methods that are used to manually remove the malware instances from the hosts.
  • Persistent Installation — Certain viruses can install themselves in a persistent way which actively counters any manual removal attempts. In such cases the victims need to restore their computers using a quality anti-spyware solution.

Updated versions of the .enc virus can also access the regional settings and extract values related to the preferences of the users. This is a popular tactic that gains information about the location of the victims. When the ransomware engine contains several ransom notes this information is used to select the most appropriate version.

When all prerequisite conditions are met the ransomware engine is started. Like other popular threats it uses a built-in list of target file type extensions. Sample lists usually act against the most popular user data: archives, documents, music, images, videos, backups and etc. The resulting data is renamed using the .enc extension. The ransomware note is created in a file called madbit encryptor: Hello, you are encrypted! which reads the following:

***!WARNING!***
***YOUR COMPUTER ARE INFECTED***
***ALL DATABASES, SITES AND USERS HOME FILES HAVE BEEN ENCRYPTED***
================================================
