Distribution of Rumba Ransomware

The Rumba ransomware is distributed using the same methods as the previous STOP virus samples. Depending on the desired scope of the target users different types of campaigns can be orchestrated. We anticipate that the first ones are going to focus on one single delivery method, while later ones can use several at once.

One of the most effective ways to spread ransomware is to launch phishing email scams. They are done by impersonating well-known companies or products — their text layout, design and text can be copied exactly requesting some ind of interaction from the recipients. Interaction with the messages will cause the Rumba ransomware infection. The virus files can be directly attached to the emails or linked somewhere in the body contents.

Ransomware operators have also been sighted to create malicious web sites that use an almost identical address, design and security certificate to well-known Internet pages. The criminals will use similar sounding domain names and embed security certificates in order to make them appear as legitimate as possible.

To increase the number of compromised users the hackers can additionally create malicious payloads that will lead to the Rumba ransomware infections when executed. There are two main types which are most commonly acquired:

  • Infected Documents — All popular document types can potentially lead to the Rumba ransomware infection: databases, spreadsheets, presentations and text documents. When they are opened by the victims a notification prompt will be spawned asking them to enable the built-in scripts (macros). If this is done the threat will automatically be deployed.
  • Malicious Setup Files — The criminals can take the legitimate application installers of popular software and modify them to include the Rumba ransomware component. This is done by selecting programs like system cleaners, creativity suites, productivity and office apps and etc.
  • All of these files can be found on file-sharing networks like BitTorrent which are one of the most popular outlets for both legitimate and pirate content. In the past we have seen ransomware like this one to be installed via browser hijackers. These are hacker-made web browser plugins which are made compatible with all major web browsers and uploaded to their repositories. When their description page is accessed the users will see an elaborate promise of adding in new features or optimizations. When they click on the “Install” button the ransomware engine will be deployed. Often the plugins are uploaded with fake developer credentials and user reviews.

    Impact of Rumba Ransomware

    The Rumba ransomware is a new threat that has emerged from the STOP ransomware family. It is being distributed in a targeted attack campaign bearing a large resemblance with the other captured versions. This leads us to believe that its behavior will not be so much different. The STOP family of malware threats allows the hacker operators to embed a wide variety of commands and modules making each independent attack potentially different.

    Most of the infections will probably begin with a data harvesting component. This is necessary in order to collect useful information both about the machines and the victim users. The retrieved data is organized into two main groups:

    • Personal User Information — The Rumba ransomware can retrieve information about the victim users which can directly expose their identity and be used for various crimes, including identity theft, abuse and fraud. The engine can be programmed to hijack their name, address, phone number, interests, location data and even any stored account credentials.
    • Machine Identification Data — The other category of information that is retrieved by the Rumba ransomware is a full report of the installed hardware components, system configuration and certain user settings. All of this is computed by an algorithm that outputs an unique infection ID which is assigned to each and every machine.

    The collected information will be processed by another module that will search for any installed security software that can interfere with the correct virus execution. Such programs include anti-virus tools, firewalls, intrusion detection systems, virtual machine hosts and sandbox environments. Their real-time engines can be disabled or entirely removed. Advanced infections may even delete themselves in case this procedure fails. This is done so in order to avoid detection.

    As soon as the infection is delivered to the target machines they can lead to a variety of malicious actions including the following:

    • Windows Registry Changes — The virus engine is capable of modifying the registry entries belonging both to the operating system and the third-party installed applications. This can have serious consequences on the stability and performance on the compromised machines. Any changes to the values used by user-installed applications can make them quit with unexpected errors.
    • Persistent Installation — The .rumba ransomware can be installed in a way which makes it very difficult to remove. By modifying the Windows Registry, boot options and configuration files the malware will be set to automatically start itself when the computer is powered on. During this process the virus can disable access to recovery menus and other mechanisms that are explored in the manual user removal guides. This means that the efficient way to remove infections is to use a professional-grade anti-spyware solution.
    • Date Deletion — Many of the STOP ransomware samples like the Rumba ransomware have the ability to access, locate and delete sensitive user data. This can include System Restore Points, Backups and Shadow Volume Copies. To effectively restore the computers a specialist recovery software must be used.

    One of the dangerous aspects of this ransomware infection is the ability to program them into co-infecting the machines with other threats like Trojans and miners. Future versions can include other components as well.

    The encryption engine will be started when all other components have finished running. Like the previous STOP ransomware samples it will use a powerful cipher (AES and RSA) to process target user data according to the built-in list. An example one will target the following files:

    • Audio files
    • Video files
    • Document files
    • Images
    • Archives
    • Databases

    The .rumba extension will be applied to all compromised data.
