Juwon Ransomware – Distribution Techniques

The Juwon ransomware is a malware which has been identified in an small attack campaign. According to the available reports the probable origin of the virus is a Korean hacker or criminal collective, the detected alias of the perpetrator(s) is Seojuwon. An alternative name is jw ransomware.

Due to the low number of captured samples it is believed that the virus samples are early test releases. We believe that in order to test out which distribution mechanism is the most effective.

One of the most popular tactics is the use of email messages that use both SPAM and phishing tactics, the emails are designed to appear as being sent by a legitimate company or service. In the body contents or the file attachments the relevant files can be added. Direct links to them or linked in multimedia content such as: images, documents, videos and in-text links.

A similar approach is the creation of malicious sites that can impersonate both download portals and vendor landing pages. They are made by using similar sounding domain names and security certificates in order to create an illusion that the site itself is legitimate. However from interaction with its elements and contents the Juwon ransomware will be installed.

Some of the Juwon ransomware distribution campaigns can additionally make use of file-sharing networks like BitTorrent where both legitimate and pirate files can be found. All of these methods can potentially also carry malicious payloads:

  • Infected Documents — They contain macro scripts that lead to the Juwon ransomware infection. Potentially all popular types can be affected: text documents, spreadsheets, presentations and databases. As soon as they are opened a message will appear asking the users to enable the scripts. If this is done the relevant infection will be started.
  • Application Setup Files — Some of the ransomware infections can be caused by the download and installation of infected application installers. They are made by taking the legitimate files from their official vendor portals and embedding the necessary code in them. To increase the number of possible victims the hackers can choose popular applications: system utilities, productivity and office apps and computer games.

Larger infection campaigns can be orchestrated by the use of browser hijackers which are made compatible with most popular web browsers. They are advertised as legitimate plugins and are often spread on the relevant browser repositories with fake user reviews and developer credentials in order to fool the victims into believing that they are downloading an useful extension. When this is done the settings of the affected browsers will be modified in order to redirect the victims to a hacker-controlled page. At the same time the Juwon ransomware will be placed on their computers.

Juwon Ransomware – Detailed Analysis

The Juwon ransomware is a testing release malware which has been captured in its early variants. The initial code analysis reveals that the Juwon ransomware is made by a hacker or collective known as Seojuwon. We have not received reports that it contains source code from any one of the popular malware families. There are two popular hypotheses behind its origins. The fist and most likely one is that the hackers have devised it by themselves. This would allow them to implement any desired changes instantly just be recompiling the virus with the new code. The other possibility is that the virus is ordered through the hacker underground markets.

Due to the fact that the captured samples are early versions they do not contain any code or components other than the ransomware engine. The most likely components that will be added in future versions are the following:

  • Data Harvesting — The virus can include a data harvesting component which can be programmed to acquire all kinds of sensitive information. The information can range from machine statistics and installed hardware components to personal data that can expose the identity of the victims — their name, address, location and any stored account credentials (username/email and password combinations). A built-in algorithm may use the data as input parameters and generate an unique infection ID which is assigned to each individual infected computer. Depending on the exact configuration the data harvesting engine can access the hard drive contents, memory, Windows Registry and even connected removable storage devices.
  • Security Override — The acquired information can be used to scan for any applications or services that can disrupt the virus execution in all stages of deployment. Such include anti-virus programs, firewalls, virtual machine hosts and debug environments.
  • Windows Registry Modifications — The engine can be used to modify existing strings in the Windows Registry or create new ones according to the hacker instructions. Changes to values used by the operating system can render certain services unusable, as well as cause serious performance and stability issues. Modifications to strings used by individual applications can make them not work as intended or crash with unexpected errors.
  • Persistent Installation — This step can make installations very difficult to remove as the engine can impact all operating system components — the Registry, boot options and configuration files. As a result of this action most menu options can be disabled which may render most manual user removal guides non-working. Persistent malware infections will usually be launched as soon as the computer is powered on.

These steps represent only a small amount of the possible components and modules. One of the most dangerous ones is associated with Trojan modules that will setup a connection to a hacker-controlled server. It will enable the hacker controllers to spy on the victims, hijack their data and take over control of their machines. This also enables them to deploy additional threats.

Future updates to the Juwon ransomware can add newer features or enhance already existing ones. Even though the currently captured samples contain only the ransomware feature we anticipate the future releases will be launched soon.

Juwon Ransomware – Encryption Process

The test versions of the Juwon ransomware may not lead to files encryption. The release-ready versions will probably use a built-in list of target file type extensions that is to be encrypted with a strong cipher. An example list may target the following data:

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

The releases that have been captured so far do not encrypt user data however they may do so in any updated versions. A lockscreen instance will be displayed in an application frame requesting a decryption fee. Proper lockscreen variants will block the normal computer interaction until the threat is completely removed.
