AcridRain Trojan – Distribution Methods
The AcridRain Trojan is a typical representative of this computer virus type. The global attack campaign has been active since July 2018 and it is speculated that various criminal groups are responsible for its launch.
A thorough analysis about its origins has lead the security researchers to an underground hacker market where the tool is sold by several accounts. Two seller accounts and one developer profile have been found to offer versions of it. This means that many malicious actors can become operators of AcridRain Trojan samples. One of its prices is quoted to be 1500 RUB which is the equivalent of about 22 US Dollars. The quoted price in the Russian currency shows that it might be created in Russia.
Buyers are offered the ability to institute various changes to the initial release versions. Subscribers can access a web-based administrative panel to control the infections.
The fact that the AcridRain Trojan can be customized by the attackers means that a variety of different techniques can be used. A primary tactic is the use of SPAM email messages containing social engineering tricks. The criminals utilize design elements and templates that mimic popular Internet services or companies that they may be registered for. The virus files can be either directly attached or linked in the body contents.
A related strategy is to create fake download pages that may mimic the vendor official download sites or popular Internet portals. These two methods are the most popular ones for spreading infected payload carriers. A popular technique is to embed scripts into documents of various types: presentations, rich text documents, databases and spreadsheets. When they are opened by the users a message box will appear asking them to enable the built-in scripts. If this is done this will trigger the initial infection engine. The other type is the creation of application installers that constitute fake copies of legitimate setup files. Typical examples are common programs frequently used by end users: creativity suites, system utilities and productivity apps.
To point to the dangerous samples the criminals can resort to the use of various scripts such as redirects, in-line links, pop-ups, ads and banners. They can also be posted on social networks and community forums via hijacked or bot accounts.
Advanced distribution tactics can use malicious web browser plugins. They are made compatible with the most popular web browsers are are usually uploaded to the most popular plugin repositories. Their descriptions present promises of new feature additions or enhancement of already existing ones. Usually fake developer credentials and user reviews are displayed. Once they are installed the default settings are usually modified to point to a hacker-controlled page. Afer this is complete the virus infection will commence.
AcridRain Trojan – Detailed Description
The main goal of the newer versions of the AcridRain Trojan is to launch a data harvesting module. It can harvest information that directly expose the victim’s identity. The engine will automatically look out for strings related to the victim’s name, address, phone number, interests, account credentials and etc. The other type of data is attributed to various metrics that can be used for statistical and optimization purposes: operating system values, hardware components and user settings.
The AcridRain Trojan can access most web browsers and access all stored information — history, bookmarks, forms data, settings, cookies and stored account credentials. This is also done for popular Internet software such as FTP clients.
This virus is also capable of recording sessions and hijacking data from popular gaming apps such as the Steam and Telegram clients. Advanced versions of it are configured to monitor the users behavior. When they access a login page for a banking platform or a cryptocurrency exchange the credentials will be automatically harvested and sent to the hacker operators.
The malicious engine establishes a secure connection to a hacker-controlled server. This allows the operators to spy on the victims in real time, gain access to their files and take over control of them at any given time.
Further analysis on the AcriRaid Trojan shows that identified infections contain a stealth protection mechanism which bypasses many security applications and services installed on the systems — anti-virus products, sandbox environments or virtual machine hosts. The fact that the AcriRaid Trojan can hook up to various processes means that it that can also carry out various network actions simulating ordinary computer actions. This makes it very hard to discover the threat using pattern analysis or other common techniques used by administrators.
The fact that the Trojan framework is modular means that it can also initiate a series of dangerous actions, all of which are fully customizable. An example list includes the following;
- Files Manipulation — The engine can identify and scan for Shadow Volume Copies and System Restore points which will be deleted. To effectively restore such hosts a professional-grade solution needs to be used.
- Additional Threats Delivery — The AcriRaid Trojan can be used as a payload mechanism for spreading other viruses.
- Blackmail — The controllers can manipulate the user’s mouse movement, hijack any entered keystrokes and spawn application windows that can be used during any blackmail tactics.
The threat is also known under these signatures:
