LimeRAT Trojan — Overview
The LimeRAT Trojan is a well-known Remote Access Trojan which can be acquired easily from the Internet. It is especially suited for beginner users as it is relatively simple to modify. It is written and compiled using the .NET Framework which means that it is compatible with all modern Microsoft Windows operating systems. As a RAT Trojan it can spread using different mechanisms.
The malware can infect its intended victims using a lot of ways. One of the popular tactics is to create payload carriers which are different kind of data which will install the virus when they are run. This can include macro-infected documents that are of all commonly run formats and setup files of popular software. They are made by taking the original files from their official sources and modifying them to include the relevant code. Take note that direct virus files as well as all carrier data can be directly offered to the intended recipients via coordinated phishing strategies. They are often designed to impersonate well-known companies and services by integrating fake design and layout. Phishing messages are usually sent via email messages and also hosted as web pages and complex sites. They are designed to look like legitimate portals, they are hosted on such domain names and may even have self-signed security certificates.
The ongoing attack campaign is focused on distribution via Microsoft Excel documents with a default password. Normally the Excel spreadsheets are password protected with a password in order to lock and reveal the contents. The default configuration of Microsoft Excel and other related spreadsheet programs are to use a default password called VelvetSweatshop. When opened using it all included macros will be run. In the case of the LimeRAT Trojan the included scripts will lead to the relevant infection.
The virus-infected files may be uploaded to file-sharing networks, this is a very popular strategy as they are used to spread both legitimate and pirate files. To accommodate large-scale infections the hackers can also integrate the Trojan installation code in malware browser plugins which are often referred as “hijackers”. They are uploaded to various repositories (including the official ones) with stolen or fake developer accounts. To manipulate the intended victims into installing them a detailed description with promises of new feature additions and performance optimizations. As the initial infections (in the current attack campaign) are done via encrypted office documents the signatures of the loader may not be recognized via common security software: firewalls, anti-virus programs and sandbox environments. The Trojan can be made small in size by using a plugin-based structure – there will be a small main engine which can download and run smaller modules when they are needed.
The Trojan will be installed using a nonstandard approach by manipulating key configuration files and boot options. This can allow the Trojan to automatically start as soon as the computer is started. The LimeRAT Trojan can prevent certain services from starting. This can prevent some manual user removal guides. One of the distinct features of the LimeRAT Trojan is the security bypass sequence. It is designed to protect the virus from being discovered by security software. It will search for active processes of anti-virus programs and virtual machine hosts. If such are detected the virus will stop itself from running. This will prevent the discovery of the Trojan. Upon running the malware it will also interact with the operating system and attempt to infect any mount removable devices or available network shares.
The Trojan engine will run as designed, the local client installed on the infected machine will establish a secure and encrypted connection to a hacker-controlled server. This will enable the hackers to overtake control of the computers, steal user data and also spy on the users. To mask the initial network configuration the server details will be retrieved from a remote Pastebin account.
The LimeRAT Trojan includes a detailed data retrieval module which includes the scanning of the memory and hard drive contents to reveal passwords and other sensitive credentials. A distinction between this malware and other Trojan is that it includes a so-called cryptocurrency grabber – it will scan the computer for any installed cryptocurrency wallets. The Trojan will automatically attempt to hijack the passwords or directly steal any stored cryptocurrency. The new versions of the Trojan will also include a ransomware malware which is fully-functional. It will encrypt target user data with a strong cipher and render the locked files inaccessible to the users and the system. To mark them the Trojan will apply the .lime extension. To make it even harder to process the data a lockscreen can be instituted which will prevent the users from properly interacting with the computers.
An additional malware which is delivered by the Trojan is a built-in cryptocurrency miner which is programmed to “mine” the Monero digital currency. This is done by downloading multiple performance-intensive tasks which will have a heavy impact on the system and the essential hardware components. When one of these tasks have completed running and are reported back to the hackers digital currency will be wired to the hacker operators.
