What is ExileRat?

ExileRat is a trojan-type remote access tool distributed by cyber criminals. At time of research, cyber criminals proliferated ExileRat using a spam email campaign that targets only Tibetan Supporters. The deceptive email contains a malicious Microsoft PowerPoint document that, once opened, injects ExileRat into the system by exploiting a Microsoft Office vulnerability.

ExileRat malware

ExileRat is a remote access tool (RAT) that allows criminals to remotely perform various actions on an infected system, steal information, and download/upload various files. Immediately after infiltration, ExileRat records the computer name, username, network adapter details, driver information. IP address, and geo-location. The recorded data is saved on a remote server. The presence of a remote access tool controlled by cyber criminals can cause various issues. These people can steal personal files, such as videos, photos, and data that might be compromising. Cyber criminals blackmail victims, requesting payment of ransoms to prevent distribution of stolen material over the internet. In addition, these people might steal various account credentials and monitor browsing activity. By gaining access to bank, email, social networks, and other personal accounts, cyber criminals can cause significant financial loss and serious privacy issues. Furthermore, they can perform various actions on the system and download data from it. Therefore, the presence of ExileRat can lead to further computer infections (e.g., ransomware or cryptominers). In summary, ExileRat may not seem dangerous on initial inspection, however, its presence can cause fatal system problems, you might lose stored data permanently, hardware might be damaged, you can lose money, and your identity could be stolen.

ExileRat shares many similarities to a number of other remote access tools distributed by cyber criminals. The list of examples includes (but it is not limited to) Nymeria, Remcos, NanoCore, and RMS. Although these applications are different and are distributed by different criminals, all pose the same threat. Cyber criminals can use them to steal information and infiltrate other malware. Therefore, eliminate these threats immediately.

How did ExileRat infiltrate my computer?

ExileRat is distributed using spam campaigns, however, at time of research, criminals targeted only CTA (Central Tibetian Administration). I.e., the list of spam email recipients were exclusively from the CTA. Nevertheless, this situation could change so that regular users or other companies and organizations are targeted. Once opened, the malicious PowerPoint document misuses Microsoft Office vulnerability (CVE-2017-0199) to download and execute a JavaScript file. This file downloads an executable file called "syshost.exe", places it in the "%AppData%" folder, and then runs it. This executable creates a scheduled task called "Diagnostic_System_Host", which runs ExileRat on each user login.

How to avoid installation of malware?

Lack of knowledge and careless behavior are the main reasons for computer infections. The key to safety is caution. Therefore, pay close attention when browsing the internet. Think twice before opening email attachments. If the file is irrelevant or the sender seem suspicious, do not open any attached link/file. Note that criminals often use deceptive messages to abuse users' curiosity. They send emails stating that recipient has won a lottery, received a package, or gained some other product free of charge. Do not fall for this scam. Have a reputable anti-virus/anti-spyware suite installed and running - these tools can detect and remove malware before it harms the system. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware .
