Enc1 Ransomware – Distribution Techniques

The Enc1 ransomware is a ransomware that has been found to infect victims using several distribution tactics. The captured samples are relatively low in number which does not give out which is the main method for delivery. It is presumed that the found samples are test or early releases and this is the reason why a large-scale distribution has not been acted on. According to the limited information the targets are English-speaking users as they constitute a large portion of the world’s population.

One of the most commonly used ransomware spread tactics is when the hacker operators send out email SPAM messages which are sent in bulk with the aim of impersonating well-known companies, services or products. They will copy the body layout and text contents and coerce the victims into interacting with the dangerous elements found within. As such the infections can be caused by opening up attached files or scripts in the emails.

The Enc1 ransomware files can be embedded in payload carriers which have the ability to infect the computers through various data. Common types are infected documents which can take the form of various popular formats: spreadsheets, presentations, text files and databases. When they are opened by the users a notification prompt will ask for their permission to enable the built-in scripts, the most common reason for this is to “correctly view the document”. As soon as this is done the Enc1 ransomware will be delivered.

The other carrier type is the application installer which embeds the necessary code into setup files of popular software. Examples include office and productivity programs, creativity suites and system optimization apps.

Infected files of both types can be spread on malicious web sites that are masked as the legitimate landing pages of products, companies, search engines and download portals. They are made to confuse the victims into thinking that they have accessed a legitimate site. Usually similar sounding domain names to the original sites and security certificates are placed.

All Enc1 ransomware can potentially be uploaded to file-sharing networks (like BitTorrent) which are a very popular source of both legitimate and pirate content. The other technique which is often considered is the inclusion of the Enc1 installation code in browser hijackers. They are dangerous plugins made for the most popular web browsers and are uploaded with fake or stolen developer credentials and user reviews to their respective repositories. The posted descriptions will read promises of performance optimization or feature additions.

Enc1 Ransomware – Detailed Analysis

The collected Enc1 ransomware samples are early test releases or development samples of the virus which is indicative that a new campaign is being planned. The information that we have on it suggests that it is not based on any one of the known malware families. Future versions can include various typical components and modules that are typical for malware of this category.

Typical infections will begin by launching a data harvesting component that is designed to retrieve sensitive information from the compromised machines. The information, in most of the cases, is used to generate an unique infection ID which can identify each infected device. It can list all installed hardware components, user settings and operating system data. If configured so it can also hijack personal information about the victim users — their name, address, phone number, interests and even stored account credentials.

The collected information can then be processed by the next module called security bypass which analyzes the data by searching for any installed security software that can interfere with the virus infection. The list of potential applications includes anti-virus, firewalls, intrusion detection services, sandbox environments and debug engines.

When these two steps have completed running the Enc1 ransomware will have control of the target machines. This can take various forms, including the following:

  • Windows Registry Changes — The virus engine can change important values that are part of the Windows Registry. Depending on the type of values that are changed the victims can experience performance issues or the inability to start certain programs and services. Value modification or deletion can make some apps quit with unexpected errors.
  • Boot Options Manipulation — The Enc1 ransomware can be set to automatically start once the computer is powered on. This mode of infection is designed to make recovery more difficult as it modifies boot options, system configuration settings and other operating system environment values. Such actions can make it impossible to follow most manual user removal guides as they rely on access to recovery options.
  • Process Manipulation — The Enc1 ransomware can hook up to existing processes (both system ones and applications) which allows the engine to spy on the victims in real-time. It can spawn new processes with administrative privileges.
  • Additional Payload Delivery — The made infections can be programmed to infect the computers with other malware.

Other features can be added as the new versions are developed. We expect that the full releases will be released in larget attack campaigns.

Enc1 Ransomware – Encryption Process

The current Enc1 ransomware version will target user data according to a built-in list of target file extensions. An example one can target the following:

  • Archives
  • Databases
  • Backups
  • Images
  • Music
  • Videos

All of the affected data will receive the _enc1 extension, note that instead of having a dot before the extension a dash is preferred. This is one important indicator that is used to differentiate it from the other viruses.

The ransom note is created in a file called decrypt_.txt which contains the following content:

Ooops. your important files are encrypted.
If you see this text, then your files are no longer accessible,
because they
have been encrypted.Perhaps you are busy looking for a way to recover your
files, but don’t waste your time. Nobody can recover your files without our
