Scarab-Horsia Virus – Distribution Ways

Scarab-Horsia is a dangerous virus threat that can be distributed to victim users using various methods. The initial attack wave is limited in number and this does not give out details about the preferred infection method. It is presumed that they might use the most popular means.

An example is the creation and coordination of attacks using spam messages. They are sent in bulk and often contain social engineering elements that are usually taken from famous web sites and online services. Using these messages the hackers behind the Scarab-Horsia virus can either bundle the files or hyperlink them in the body contents. In connection with this several different type of payloads can be used.

One of the most common methods is of malware installers. They are hacker-modified versions of famous application such a system utilities, computer games and creativity suites. These threats are made by taking the original installer files and modifying them with the malware code.

The other way relies on infected documents that can take the form of any type: rich text documents, spreadsheets or presentations. When they are opened by the victims a notification prompt will appear that prompts them to enable the built-in scripts. If this is done then the virus will be downloaded from a remote location and executed on the local system.

The Scarab-Horsia can be distributed using browser hijacker. They are malware plugins made for the most popular web browsers (Mozilla Firefox, Google Chrome, Internet Explorer, Opera, Safari and Microsoft Edge). Once they are installed on the victim machines the users will be redirected to a malware site. The dangerous code changes settings such as the default home page, new tabs page and search engine. The next step is to infect the systems with the Scarab-Horsia virus.

Scarab-Horsia Virus – In-Depth Analysis

It is very possible that this threat has been developed by the original authors of the Scarab ransomware family. Another possibility is that the original Scarab source code has been acquired through the hacker underground communities and picked up by an individual hacker or criminal collective.

One of the first components that are launched once the virus has been deployed onto the victims is the information gathering component. It is used to gather sensitive information about the user and the system. The obtained information is usually classified into two categories. The first one is labeled as campaign metrics and is used primarily to judge how effective the attacks are. Example data includes details about the hardware components and certain operating system related strings. The second type of information refers to personal data. It can include anything from the victim’s name to their physical location. Sensitive credentials about their identity are revealed to the hackers: name, location, interests, passwords and account credentials.

The next step would be to use the gathered information with a stealth protection module. It can be used to bypass any security protection software such as anti-virus products, sandbox environments or debug software. In the case this isn’t possible the virus may automatically remove itself to avoid detection.

Infections with the Scarab-Horsia virus can incur various system changes. They can be changed according to the targets or the attack campaign itself. An example would be Windows Registry modifications that can cause certain applications or operating system services to fail. Overall performance may be affected as well.

If the threat is programmed to create a persistent state of execution then the Scarab-Horsia virus can also impact boot options. As a consequence the virus can disallow access to the recovery menu. Data recovery can be made difficult by deleting all the found Shadow Volume Copies of user data.

Scarab-Horsia Virus – Encryption Process

When all components have executed correctly the ransomware engine is started. The associated component uses a built-in list of target file type extensions. Example data includes:

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

All victim files are renamed with the .horsia@airmail.cc extension. Depending on the configuration the original file names may also be renamed with a random string. A custom cipher is used which makes it very difficult to restore the files without the use of professional software.

A ransomware note is crafted in a file called HOW TO RECOVER ENCRYPTED FILES.TXT which contains the following contents:
