.GEFEST Scarab Ransomware – Distribution Techniques

The .GEFEST Scarab ransomware is a new version of this family of viruses. The associated samples have been captured from live attack campaigns. This makes us believe that several methods may be used at once.

One of the main methods used by Scarab ransomware versions like this one is the coordination of phishing messages that are made by using exploit kits to send out large volumes of emails. The victims will receive messages that look like legitimate notifications from well-known companies or services that they might be using. The infection code might be embedded in scripts or directly attached to the emails.

The .GEFEST virus files can be uploaded to malicious web sites that pose as safe download portals, landing pages or product pages. They embedded code can be placed in various payloads two of the popular ones are the following:

  • Documents — The necessary infection code can be embedded in the most popular document types: presentations, databases, spreadsheets and text documents. When they are opened by the victims a prompt will appear asking them to run the built-in code. This will trigger the Scarab ransomware delivery.
  • Application Installers — The hackers can take the setup files of popular software that is often downloaded by most computer users: office and productivity tools, creativity suites and system utilities. As soon as they are started the virus infection will be started.

All files can also be spread on file-sharing networks like BitTorrent which are popular for spreading both pirate and free content.

Scarab ransomware threats like the .GEFEST samples can also be delivered via malicious browser plugins, alternatively known as hijackers. They are often uploaded to the relevant repositories with fake user reviews or developer credentials with the hope of coercing the readers into installing them. Whenever this is done dangerous modifications will be made to the compatible browsers and the threat delivered.

.GEFEST Scarab Ransomware – Detailed Analysis

The .GEFEST Scarab ransomware as a new sample release of this malware family can be used to carry out an extensive list of actions all depending upon the configuration file issued by the hackers. Some of them include the following:

  • Boot Options Modifications — The .GEFEST Scarab ransomware can install itself in a way which modifies the core boot settings. As a result the virus will start itself automatically once the computer powers on. The made changes will also make it impossible to follow most manual recovery methods.
  • Information Retrieval — The engine can scan the system for sensitive information about the identity of the victim users and machine metrics. The retrieved information can directly expose the users by searching for strings like their name, address, phone number, location and any stored account credentials information.
  • Security Services Override — There are several types of security services and applications that the virus engine can look for and block. This will enable it to silently install itself on the target computers.
  • Windows Registry Changes — One of the most dangerous effects of Scarab ransomware infections, including the .GEFEST one, is the modification of the Registry of the compromised machines. This can render the system completely unusable and behave in strange ways.
  • Additional Payload Delivery — Many ransomware variants of this type choose to deploy other threats as well. This is done as the .GEFEST Scarab ransomware has already bypassed the security barriers.

A dangerous scenario that is sometimes executed is when the .GEEST Scarab ransomware delivers a Trojan module and runs it. This will establish an always-on connection with the hacker-controlled server which is used by the operators to take over control of the affected hosts.

.GEFEST Scarab Ransomware – Encryption Process

When all prerequisite commands have completed the encryption process will be started. It will search for sensitive user data according to a built-in list of target file type extensions. An example one is the following:

  • Archives
  • Backups

All victim files will be renamed with the .GEFEST extension which contains the email address used by the operators. The ransomware note will be created in a file called HOW TO RECOVER ENCRYPTED FILES.TXT that reads the following:
