Satana Ransomware – Distribution Techniques

The Satana ransomware is a new malware which has just been identified in an ongoing attack campaign. The captured samples indicate that it is possible that several methods have been used. Such viruses are often spread with phishing email messages that will coerce the victim targets into interacting with the displayed body contents. They will be designed to appear as service messages from well-known companies or services that the victims might be using. An alternative would be to directly attach them to the messages.

Satana ransomware strains may also be featured on fake web sites that can impersonate download portals or landing pages. These two methods are also widely used to distribute payload carriers of which there are two main types:

  • Application Installers — The malicious actors behind the Satana ransomware can also embed the virus installation scripts in setup files of popular software. Examples include programs that are downloaded by end users: creativity suites, system utilities, office packages and etc. The original packages are downloaded from their official sources and the dangerous contents added. They will be then spread via the distribution channels — usually fake web sites or file-sharing networks. BitTorrent is one of the most popular options as it is a mechanism for sharing both legitimate and pirate content.
  • Infected Documents — The other popular payload method is the creation and distribution of documents containing malicious scripts. This is possible with all popular document formats: rich text documents, spreadsheets, presentations and databases. Whenever they are opened by the users a message will appear asking them to enable the built-in scripts in order to view the file correctly. If this is done the virus infection command will be started.

Larger infection campaigns can be orchestrated by the programming of purpose-built browser hijackers which are dangerous extensions made for the most popular web browsers. They are usually found on the associated repositories (or “stores”), frequently making use of fake or stolen developer credentials and user reviews. Their descriptions will include promises of feature additions or optimizations. However upon installation they will often change the settings in order to redirect the victims to a hacker-controlled landing page. At the same time the virus infection will follow.

Satana Ransomware – Detailed Analysis

The captured Satana ransomware samples showcase that the virus appears to be made entirely by the criminals which are spreading it. It is very possible that it is an original creation and not based on any of the known malware families. If the threat is not written by this criminal collective then it may be ordered from one of the underground hacker markets.

The security analysis shows that the Satana ransomware does include a collection of modules that are launched as soon as the infection occurs.

One of the first ones that is run is the persistent installation configuration setting which has been confirmed to modify entries in the Windows Registry. When modifications to the operating system belonging values are made then the victims can expect serious performance issues and troubles when accessing common functions. On the other hand modifications to individual applications can render them inaccessible or non-working. The persistent installation has also been found to modify important system configuration files, boot options and the settings of the operating system. In most cases this will mean that the Satana ransomware will be run every time the computer is booted. Access to recovery menus may be disabled which renders most manual user recovery guides non-working.

What is more dangerous about the Satana ransomware is that it has been found to contain advanced fingerprinting techniques that will extract sensitive data from the compromised machines. What is known is that it will construct a unique infection ID which is assigned to each infected host. The following information is harvested from the machines:

  • Windows Operating System Credentials — The ransomware engine will identify and harvest all account credentials of the operating system.
  • Kernel Information — This will check for details about the installed operating system. To a certain degree this can be used to identify if the host is a virtual machine, representing a form of a security check. If programmed accordingly the infection can stop if such is detected.
  • Cryptographic Machine ID — This information is retrieved in order to generate the unique infection ID. This string is individual to every single computer as it is based on the installed hardware components.

As soon as these modules have completed running the Satana ransomware will have access to all running processes being able to hijack important data from them. What we know is that the files on the infected machines can be both accessed, modified and deleted. System data is also affected, future versions can be programmed to locate and remove System Backups, System Restore Points and other important information.

It seems that the modular structure of the virus allows it to be updated further with other components as well. We anticipate that a Trojan module might be added. It will use a local client which will create a persistent connection to a hacker-controlled server. This tunnel allows the malicious operators to spy on the users, steal their data and also overtake control of the machines. This technique also allows the hackers to deploy other threats.

Satana Ransomware – Encryption Process

The Satana ransomware uses the familiar mode of operations that is used by most popular malware engines — a powerful cipher is used to encrypt valuable user data according to a built-in list of target file type extensions. A full list is not yet available however the most common ones are the following:

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

The .satana extension will be added to all victim data. The associated ransomware file will be written in files called HOW TO DECRYPT YOUR FILES — they may be either text files or HTML rich text ones.
