StilachiRAT is a dangerous Remote Access Trojan (RAT) that can infiltrate a system, steal sensitive data, and allow cybercriminals to control the infected device remotely. This malware uses advanced evasion techniques to remain undetected, making it a significant threat to individuals and organizations. StilachiRAT is particularly dangerous due to its ability to monitor activity, steal credentials, manipulate system settings, and even restore itself if removed. Immediate action is required to remove this RAT and secure the affected system.

How StilachiRAT Works
Once it infiltrates a system, StilachiRAT gathers detailed information, including:
- Operating system details, BIOS, device identifiers, and camera presence.
- A unique system ID using the device’s serial number and an attacker’s RSA key.
- Stored passwords and credentials from Google Chrome.
- Active RDP sessions by copying security information and impersonating users.
- Clipboard contents, looking for passwords, cryptocurrency keys, and personal details.
Additionally, StilachiRAT targets cryptocurrency wallet extensions in Google Chrome, such as MetaMask, Trust Wallet, Coinbase Wallet, OKX Wallet, Phantom, and many others.
The RAT executes commands from a Command and Control (C2) server, enabling attackers to:
- Restart the system, clear logs, and steal credentials.
- Run applications, manipulate system windows, and change registry values.
- Suspend the system and delete security logs to evade detection.
Furthermore, StilachiRAT includes a self-preservation mechanism that allows it to restore deleted files and modify system settings to keep itself running.
How to Remove StilachiRAT
Step 1: Disconnect from the Internet
- Disconnect your device from the internet to prevent further communication with the attacker’s server.
Step 2: Boot into Safe Mode
- Windows 10/11:
- Press Win + R, type
msconfig
, and press Enter. - Go to the Boot tab, check Safe boot, and select Minimal. Click OK and restart.
Step 3: Terminate Suspicious Processes
- Press Ctrl + Shift + Esc to open Task Manager.
- Look for unknown processes consuming high CPU or memory.
- Right-click and select End Task.
Step 4: Delete Malicious Files
- Press Win + R, type
%AppData%
, and press Enter. - Look for recently created suspicious folders and delete them.
- Repeat the process for
%Temp%
,%LocalAppData%
, andC:\Windows\Temp
.
Step 5: Remove StilachiRAT Registry Entries

regedit
, and press Enter. - Navigate to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- Look for suspicious entries and delete them.
Step 6: Scan with Anti-Malware Software
- Use a reputable anti-malware tool like SpyHunter to detect and remove StilachiRAT.
Step 7: Change All Passwords
- Since StilachiRAT steals credentials, change all passwords immediately, especially for banking, email, and cryptocurrency accounts.
Preventive Measures
To avoid reinfection and protect your system, follow these security best practices:
- Be Cautious with Email Attachments – Do not open attachments from unknown senders.
- Avoid Downloading Software Cracks – Many pirated programs come bundled with malware.
- Use Strong, Unique Passwords – Enable two-factor authentication (2FA) wherever possible.
- Keep Software and OS Updated – Install updates to patch security vulnerabilities.
- Install a Reliable Antivirus Program – Use an advanced anti-malware tool like SpyHunter to monitor and block threats.
- Backup Important Files – Regularly create offline backups to prevent data loss.
Conclusion
StilachiRAT is a severe cybersecurity threat capable of stealing sensitive data, monitoring user activity, and granting hackers full control over infected systems. Due to its ability to evade detection and reinstate itself, manual removal can be challenging. Therefore, using professional anti-malware software and following security best practices is critical. Immediate removal is necessary to safeguard personal information and financial assets.
