The Shrug virus is a recently discovered ransomware threat that is being distributed in a limited infection campaign. At the moment there is no information about the identity of the hacker or criminal collective it. The available reports concerning showcase that the released strains target computer end users on a global scale.

One of the main methods used by computer hackers relies on the distribution of email spam messages. They use social engineering tactics that imitate the notification messages of well-known Internet companies and services. They are made by taking the legitimate design elements from them and implementing the text and graphics into the fake messages.

Along with the fake download sites the hackers can create infected payloads that are an important delivery tactic for viruses. There are two main types that are usually considered:

  • Infected Documents — The Shrug virus code can be embedded in files of various types: rich text documents, spreadsheets, presentations and databases. They include macros that are responsible for the virus infections. Once the files are opened by the victims a notification box will be spawned which asks them to enable the built-in scripts.
  • Application Installers — The Shrug virus code can be embedded in software setup packages that are popularly downloaded from end users: creativity suites, productivity apps or system utlities. The way they are made is by taking the the legitimate installers from the official vendor sites and reconfiguring with the virus code.

The Shrug virus can also be delivered using browser hjackers — they are malicious browser extensions that are spread on the various web browser repositories. They usually rely on fake developer credentials and user reviews.

Shrug virus – In-Depth Analysis

The Shrug virus is a being pushed to users worldwide by an unknown hacker or criminal group. The captured strains have been analyzed and reports state that only a basic ransomware engine is implemented. This means that in future releases the operators behind it can include other modules in implement a more complex behavior pattern.

The virus infections can begin with a data harvesting step that can hijack all kinds of sensitive information. Such behavior can be used to expose the identity of the users or optimize the attack campaigns. Example data includes the following: certain operating system values, regional settings, user’s name, their address, stored account credentials and etc.

The data can then be processed by another component called stealth protection which counters any security software and countermeasures found on the computer. Using an application scan it find and disable the real-time engines of anti-virus software,sandbox environments and virtual machine hosts.

The next steps in the behavior pattern are used to modify the operating system by editing or creating new Windows Registry entries. When those belonging to any user-installed applications are changed then certain functions may not be available. If the operating system ones are modified then overall performance can suffer.

To make the Shrug virus more difficult to remove the criminals can institute it as a persistent threat — the malicious engine can be automatically started once the computer is powered on. It can also remove the ability to enter the boot recovery menu which counters most manual removal instructions.

The associated engine can also be used to prevente data recovery by removing all found Shadow Volume Copies and System Restore Data which requires the use of a professional-grade data recovery solution. Refer to our instructions for specific details.

Advanced virus threats also make use of a Trojan module that connects to a hacker-controlled server that is used to report the infections. Using it the criminals can spy on the victims in real-time, as well as take over control of the affected machines. In certain cases this connection is used to deploy additional threats.

Shrug virus — Encryption

The ransomware engine uses a strong cipher that affectes victim files based on a built-in list of target data. An example list can include the following:

  • Images
  • Videos
