ARGUS CRYPTOR V1.0 Virus – Distribution Techniques

The ARGUS CRYPTOR V1.0 virus as a new ransomware threat is being distributed in an initial campaign targeting a pre-selected list of targets. It is anticipated that future releases will use a much more encompassing campaign and with several different methods at once.

A popular method is the use of email SPAM messages — they are sent in bulk and contain phishing tactics that all attempt to scam the recipients into thinking that they are receiving a legitimate message. The emails are designed with elements taken from well-known sites or services that they might use. The virus file can be directly attached to the emails or linked in the body contents.

A related mechanism is the creation of web sites that use a similar mechanism — they are fake copies of vendor download sites, Internet portals or review sites. By interacting with elements the ARGUS CRYPTOR V1.0 virus will be delivered to the vicims.

The virus may also be spread through various file-sharing networks which are often used in the distribution of both legitimate and pirate content. These three methods are also used to carry infected payloads which can cause infections with the ARGUS CRYPTOR V1.0 virus. Such an example is a malicious setup file which is made by taking the installers of popular end-user software and adding the virus code in them. A similar strategy is the creation of infected documents, the carriers can be of any of the common types: spreadsheets, databases, rich text documents and presentations. If opened a notification box will appear asking the users to enable the built-in scripts. This will trigger the infection.

Large-scale attack campaigns can alternatively make use of distribution via browser hijackers. They are malicious web browser plugins which are made compatible with the most popular web browsers and uploaded to their respective repositories. The strains use fake developer credentials and user reviews in order to further manipulate the victim users into adding them to their browsers. As soon as they are installed they will start to cause changes to the browser, system and also deploy the virus threat.

The captured strains so far showcase that the majority of the impacted users are English-speaking.

ARGUS CRYPTOR V1.0 Virus – Detailed Analysis

The security analysis performed on the ARGUS CRYPTOR V1.0 virus indicates that it does not originate from any of the known malicious families. This means that it is likely that the individual or group behind it may have developed it. The other possible source is a custom order from the hacker underground markets.

It appears that the virus does follow a modular framework as the acquired samples showcase a step-by-step pattern.

The infection engine will be started as soon as the virus is deployed on the target devices. The analysis shows that the ransomware will attempt to install itself as a persistent threat — it will disable the boot recovery menu and may also add entries to the Windows Registry or various Windows configuration files. Such modifications will launch the malicious module every time the computer boots and may render manual user removal guides non-working.

This module is also used to delete system data such as recovery images, shadow volume copies and other information that is used during the virus removal and restore process.

A nonstandard component is included in this ransomware. When executed it will start to zero out the disk by deleting sensitive data and leading to problems with file data.

There are other possible additions that can be included in future releases of the ARGUS CRYPTOR V1.0 virus:

  • Information Retrieval — Such virus modules make use of scripts and stand-alone components in order to hijack data that can expose the identity of the victim users. The module will search for specific strings such as their name, address, phone number and any stored account credentials.
  • Machine Identification — This module can assign a unique ID to each machine by looking out for strings such as the installed hardware components, user settings and operating system variables.
  • Additional Virus Deployments — Infections with ransomware of this type can be used in causing other infections. They can range from browser hijackers to Trojans.

ARGUS CRYPTOR V1.0 Virus – Encryption Process

As soon as all prior components have completed execution the built-in ransomware code will be engaged. Like other popular threats it will make use of a built-in list of target file type extensions that will be processed wih a strong cipher and rendered inaccessible. An example list is the following:

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

As a result all victim files will be renamed with the .ARGUS extension. To blackmail the victims into paying the hacker operators a “decryption fee” they will also produce a ransomware note with the ARGUS-DECRYPT.html file name. It will be launched in a web browser window and request that the users visit a payment gateway page using the Tor Browser.

A desktop wallpaper is also applied which reads the following:

Dear admin!
All your files has been encrypted!
For encrypting used cryptographic algorithm RSA2048.
Only we can provide you decryptor.

You can find this file everywhere on your PC.
