What is ExileRat?

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

As mentioned above, ExileRat is a remote access tool (RAT) which allows to remotely perform various actions on the infected system, steal various information and download/upload various files. Immediately after infiltrating, ExileRat gathers computer's name, username, network adapter details, driver info, IP address and geo-location. All gathered data is saved in a remote server. Now presence of a remote access tool (which is controlled by cyber criminals) can cause a variety of issues. First of all, these persons may steal various personal files, such as videos, photos, and other data that can be compromising. After gaining such data, cyber criminals can blackmail victims by asking to pay money otherwise they'll spread stolen material over the Internet. On top of that, these persons might steal various account credentials and monitor user's web browsing activity. By gaining access to bank, email, social network, and other personal accounts cyber criminals might cause significant financial losses, as well as serious privacy issues. Moreover, since crooks can perform various actions on the system and download various data, presence of ExileRat may lead to further computer infections (e.g., ransomware or cryptominers). In summary, ExileRat might not seem dangerous on the first glance, however, it's presence can be fatal to the system - you might lose stored data permanently, your hardware may be damaged, you can lose money and your identity might 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 crooks, all of them pose the exact same threats to the user. Cyber criminals can use them to steal information, infiltrate other malware, and so on so forth. Therefore, elimination is paramount.

How did ExileRat infiltrate my computer?

As mentioned above, paavadinimas is distributed using email spam campaigns. It is, however, worth mentioning that at the time of research crooks were targeting only CTA (Central Tibetian Administartion). In other words, the list of emails that spam was sent to belongs only to the CTA. Nevertheless, this doesn't mean that the situation won't eventually change and that crooks will target regular users or other companies/organizations. Once opened, the malicious PowerPoint document abuses Microsoft Office's vulnerability (CVE-2017-0199) in order to download and execute a JavaScript file. This file downloads an executable called "syshost.exe", drops it in the "%AppData%" folder and 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?

In order to prevent this situation users must firstly realize that lack of knowledge and reckless behavior are the main reasons for computer infections. The key to it's safety is caution. Hence, paying close attention when browsing the Internet is a must. Always think twice before opening email attachments. If the file is irrelevant and/or the sender looks suspicious - do not open any attached link/file. Note that crooks often use deceptive messages in order to abuse users' curiosity. They send emails stating that recipient has won a lottery, received a package, or something else for free. Therefore, you should never fall for it. On top of that, always have a reputable anti-virus/anti-spyware suite installed and running - these tools are very helpful when it comes to cyber security, because they're more than likely to 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.
