How to remove StilachiRAT from the operating system
Written by Tomas Meskauskas on
What kind of malware is StilachiRAT?
StilachiRAT is a remote access trojan (RAT) that employs advanced techniques to evade detection, maintain persistence in the infected system, and steal a wide range of sensitive data. This malware poses a significant threat to both individuals and organizations. Thus, it should be eliminated from compromised devices immediately.
More about StilachiRAT
Once infiltrated, StilachiRAT collects information from the infected system, such as the operating system, device identifiers, BIOS, and whether a camera is present. The malware also creates a unique ID based on the system's serial number and the attacker's public RSA key.
Also, StilachiRAT targets certain cryptocurrency wallet extensions for the Google Chrome browser and checks if they are installed on the system. These include: BNB Chain Wallet, Bitget Wallet (BitKeep), Braavos – Starknet Wallet, Coinbase Wallet, Compass Wallet for Sei, ConfluxPortal, Fractal Wallet, Keplr, Leap Cosmos Wallet, Manta Wallet, MetaMask (Ethereum), OKX Wallet, Phantom, Plug, Sui Wallet, Station Wallet, TokenPocket, Trust Wallet, and TronLink.
StilachiRAT also steals saved login details from Google Chrome and monitors RDP sessions by tracking open windows and copying security information to impersonate users. It monitors active sessions, opens new windows, and copies security privileges to run programs with those permissions.
Moreover, the RAT gathers information about the installed software and which applications are running. This allows cybercriminals to analyze user activity. Another StilachiRAT's capability is to monitor the clipboard. It looks for sensitive information like passwords, cryptocurrency keys, and personal details.
Moreover, StilachiRAT can execute a wide range of commands sent from the C2 server, such as restarting the system, clearing logs, stealing credentials, running applications, and manipulating system windows. It can also suspend the system, change registry values, and list open windows.
Additionally, StilachiRAT has a mechanism that ensures it stays active on the infected system. It constantly checks for its files (the program and its supporting files). If any of these files are deleted, it can restore them from a backup. Additionally, if it is running as a Windows service, it can modify system settings to restart itself and keep running.
Lastly, StilachiRAT hides its actions to avoid detection by deleting logs and checking for analysis tools. It also uses encryption methods to cover its code, making it harder for security experts to analyze. These techniques help it stay undetected longer.

How did StilachiRAT infiltrate my computer?
Threat actors deliver malware using various techniques. They send emails containing malicious links or files via email, hide malware in cracking tools or pirated software, and exploit vulnerabilities in outdated software or operating systems. They also use technical support scams and malicious advertisements.
Additionally, cybercriminals can distribute malware through infected USB drives, compromised or fake web pages, P2P networks, third-party downloaders, and similar channels. Typically, their goal is to trick users into performing actions leading to malware execution.
How to avoid installation of malware?
Always get software from reputable sources, like official websites or app stores. Be wary of pop-ups, ads, and links on unfamiliar websites, and avoid clicking on them. Do not permit untrusted sites to send you notifications, and never open links or attachments in emails from unfamiliar senders.
Keep your system and software up to date, and run regular scans with a trusted security program for added protection. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?
Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Combo Cleaner Antivirus for Windows.
If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check 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".
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.
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 Combo Cleaner Antivirus for Windows.
