What is Remcos?

Remcos (Remote Control and Surveillance) is a Remote Access Tool (RAT) that anyone can purchase and use for whatever purpose they wish. The tool itself is is presented as legitimate, however, although Remcos's developers strictly forbid misuse, some cyber criminals use this tool to generate revenue by various malicious means. Research shows that many cyber criminals proliferate these infections using spam email campaigns. Some examples include "DHL Email Virus" and "Arrival Notice Email Virus".

As mentioned above, Remcos is a high-end remote access tool that allows users to control systems remotely. If misused, however, Remcos can be an extremely dangerous threat. Research shows that cyber criminals send thousands of misleading emails that contain malicious attachments (typically MS Office documents) that infiltrate Remcos into the system. All this is done without users' consent. Remcos grants access to computers and, thus cyber criminals can cause damage to systems and many other issues. They might retrieve personal information, such as saved passwords, private data, and so on. Cyber criminals can also monitor the screen in real-time, thus seeing what users are doing on their systems and on the internet. The tool can also be used to download files. Therefore, cyber criminals might inject system with other viruses (e.g., ransomware). Ultimately, the presence of Remcos RAT can lead to significant financial/data issues, various privacy issues, and further system infections. If you have recently opened malicious attachments and suspect that Remcos has infiltrated your system, scan the system with a reputable anti-virus/anti-spyware suite and eliminate all detected threats.

There are dozens of various viruses distributed using spam campaigns. The list of examples includes (but is not limited to) Adwind, Hancitor, TrickBot, NanoCore, and Hawkeye. These viruses are developed by different cyber criminals and their behavior/functionality also differs correspondingly - some gather information, others cause chain infections (infiltrate other malware into the system), provide access to the system, etc. Nevertheless, all pose a direct threat to your privacy and/or computer safety. Therefore, eliminate all malware immediately.

How did Remcos infiltrate my computer?

As mentioned above, Remcos is typically proliferated using spam campaigns. Users receive deceptive emails that contain malicious MS Office attachments. The messages typically states that the user has received a package, has a bill to pay, or similar. In any case, users are encouraged to open the attachment immediately. Once opened, the file encourages users to enable macro commands, otherwise the content will not be displayed properly. By enabling macros, users grant files permission to execute commands that infiltrate viruses into the system. This malware distribution method is simple and effective, but does have flaws. The malware will only be downloaded if the user opens attachments using MS Office. If the file is opened using any other software, the virus will not be able to infiltrate the system. Furthermore, Remcos works only on the Windows Operating System and users of other platforms are safe.

How to avoid installation of malware?

To prevent this situation, be very cautious when browsing the internet. Think twice before opening email attachments. If the file/link is irrelevant or has been received from a suspicious/unrecognizable sender, do not open it. You should delete these emails without reading. As mentioned above, many malicious attachments are MS Office documents. Newer versions of Microsoft Office (2010 and later) have "Protected View" mode, which prevents malicious executables from automatically executing macros. Therefore, we advise to avoid using older versions of this software. Have a reputable anti-virus/anti-spyware suite installed and running. These tools commonly detect and eliminate malware before any damage is done. The main reasons for computer infections are poor knowledge and careless behavior - the key to safety is caution. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Spyhunter for Windows.
