tRat Trojan – Distribution Methods
The tRat Trojan is believed to be created by the same criminal group known as TA505. It is well-known to security researchers as these hackers were responsible for a lot of targeted campaigns carrying Dridex and Locky samples in 2014, 2016 and 2017. The main method of distribution by them is the use of email SPAM campaigns utilizing several of the popular phishing tactics. It appears that after the Dridex and Locky attacks the group has shifted their tactics into using other malware, including Trojans.
The tRat samples captured in the current and ongoing attacks appear to be newly-created threats, possibly by the the collective itself.
The first wave of detected malware was detected in the end of September 2018 where the an unknown group (possibly not TA505) distributed infected office documents. Several phishing scam tactics are used to fool the recipients into thinking that they have a received a legitimate notification from a well-known source, usually a company or service that they recognize. Some of the tactics are the following:
- Norton Document — Upon opening this email message the users will be shown the “Norton by Symantec” logo and the following text: This document has been secured by Norton Security Premium. To view this Protected Document, click “Enable Content” button.
- Trip Advisor Video Message — This type of phishing scams relies on the sending of rich text documents that appear to be sent by the popular Trip Advisor portal. Upon opening them a loading screen that fools the users into thinking that an embedded video was unable to be opened. A text in a green color underneath it reads the following: To load video click Enable Editing and Enable Content button.
- Invoices — A separate phishing campaign in October, this time operated by the TA505 hackers, was detected. It uses both Microsoft Word rich text documents and Microsoft Publisher to create false invoices. The targets are primarily businesses or large corporations. To further make the messages look believable enough they are personalized as being sent by real people.
We anticipate that future releases and campaigns of the tRat Trojan can use other strategies as well. Popular methods include the deployment of malicious application installers which are hacker-modified versions of legitimate and popular software: productivity apps, system utilities and creativity suites. The installers are taken from the official vendor download sites and modified with the the necessary code.
Advanced distribution campaigns may be coordinated through browser hijackers which are hacker-created extensions made for the most browsers. They are uploaded to the relevant repositories, often utilizing fake user reviews and developer credentials. Whenever they are installed in most cases modifications to the settings will be done — home page, new tabs page and search engine in order to redirect the victims to a hacker-controlled page. Following this the malicious payload will be inserted.
tRat Trojan – Detailed Description
One of the first actions done by the tRat Trojan is to install itself as a persistent threat. The mechanism used by the captured samples is to copy the main engine file to a folder of a widely used software or the operating system itself. By doing so the the Trojan files will be masked as belonging to the relevant app or service. An additional measure is the creation of a a startup value which executes the Trojan every time the computer starts.
An additional measure is the encryption of the virus code which makes it harder to detect using ordinary application scans.
The main goal of the tRat Trojan is to create a stable a secure and persistent connection to a hacker-controlled server. This allows the hacker operators to spy on the victims, steal their data and deploy other payloads.
One of the actions done by the criminals is to acquire data from the systems. There are two groups of information that are outlined:
- Private Data — The engine will search for strings that can directly expose the identity of the victims. This is done by looking for strings such as their name, location, interests and any stored account credentials (username, email and password combinations). It can search for strings found both on the hard drive, operating system and the contents of third-party applications.
- Campaign Metrics — It can generates a report of the installed hardware components. regional and user settings and operating system environment values.
It appears that the hacker criminals make use of tRat’s modular framework. It allows them to interactively include other threats to the system. Examples include other the installation of other threats: ransomware, miners and etc.
