JSWORM Ransomware – Distribution Techniques

The JSWORM ransomware is a newly discovered malicious threat that has been identified in a small-sized attack campaign. The number of captured samples is low which does not give out the main distribution method.

One of the most popular techniques for sending out ransomware is to coordinate email SPAM campaigns. They will use phishing tactics manipulating the victims into thinking that they have received a legitimate notification from a well-known company or service. The infection can be done by interacting with the body contents or any attached files.

Most ransomware infections can be caused by launching malicious payload carriers that can take various forms. An example one would be an infected document containing macros with the necessary instructions. All popular types can be infected: spreadsheets, presentations, text documents and databases. When they are opened by the victims а prompt will appear asking for them to enable the macros. Various reasons can be quoted, the most popular one being that the document cannot be properly opened without them. Enabling this prompt will lead to the virus infection.

The other payload carrier that can be utilized for JSWORM ransomware infections is the application installer. The criminal collective can embed the necessary code in setup files of popular software. As soon as they are run the ransomware will be deployed. They are made by taking the legitimate files and modifying them with the necessary code instructions.

All of these files can be distributed on file-sharing networks like BitTorrent where both legitimate and pirate content is shared. Another possible source is the network of malicious sites that can be created to support a virus distribution campaign. They will copy the design elements and body contents of real and trustworthy sites, as well as use similar sounding domain names and security certificates (often stolen) to mask their fraud identity.

Larger campaigns can target victims using browser hijackers — hacker-made plugins made for most popular web browsers. They will be offered as legitimate extensions which are described as offering updated functionality or performance enhancements. Often they are uploaded to the relevant repositories using fake user reviews and developer credentials and as soon as they are installed the virus installation will take place.

JSWORM Ransomware – Detailed Analysis

The JSWORM ransomware is considered to be an early testing release and in its current form does not contain any advanced components. It is possible that future versions of it will copy the behavior of other well-known viruses. Most of them begin the infection with a data harvesting command which instructs the the engine to scan the local contents in search of sensitive information. It is primarily used to generate an unique infection ID that is assigned to each infected host and is usually made up of input values taken from the installed hardware components, user settings and operating system environment values. It can also be configured to directly expose the identity of the victims by searching for strings that contain their name, address, phone number, location and account credentials.

The collected information can then be processed by the next module called security bypass. It will search for security software that can interfere with the virus installation: all forms of anti-virus engines, sandbox environments, debug engines and virtual machine hosts. If such are found then they will be bypassed or even deleted.

When these two steps have been completed the JSWORM ransomware will have obtained complete control of the machnes. This will allow it to carry out other malicious actions like the following:

  • Windows Registry Values — The ransomware engine is fully capable of modifying the existing strings of the Windows Registry or to create new ones for itself. When system ones are affected then the overall performance and stability of the computers is going to be affected. Changes to third-party installed programs may cause them to quit with unexpected errors.
  • Boot Modifications — The engine can access the boot records and mdify them to run itself as soon as the computer is powered on. Every time the computer is booted the JSWORM instance will be started. Such actions also disable access to the recovery boot menus. They are used to recover the computers with manual instructions.
  • Additional Changes — Other modifications include the delivery of other payloads and changes to the operating system. By hooking up to other processes the JSWORM instance can reconfigure input and output in real-time.

Future updates of the JSWORM can include any other malicious component that the criminal collective deems necessary for the attacks.

JSWORM Ransomware – Encryption Process

It is presumed that the JSWORM ransomware will use a list of target file type extensions that are to be encrypted with a powerful cipher. Usually data that is considered sensitive and personal is affected in order to coerce the victim users into paying the attackers a decryption fee. Example data includes the following:

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

The affected files will be renamed with the .JSWORM extension. The associated ransomware note will be placed in a HTML file with the following message:
