🦠 What is StilachiRAT and How Does it Work?

In November 2024, Microsoft researchers uncovered StilachiRAT, a new remote access trojan (RAT) that stealthily targets sensitive data. The trojan's main focus is on cryptocurrency wallets stored in Google Chrome extensions, along with credentials and clipboard data, making it a particularly dangerous threat for crypto users.

🔐 What Methods Does StilachiRAT Use to Steal Data?

StilachiRAT employs several sophisticated techniques to steal sensitive information:

• System Information Collection: It actively gathers browser configurations, saved passwords, and cryptocurrency wallet data.
• Clipboard Monitoring: The trojan constantly monitors the clipboard for passwords and wallet details, instantly grabbing them when copied.
• Stealing Crypto Keys: Using the information it collects, StilachiRAT can snatch cryptocurrency keys and credentials and send them to the attackers.

🌐 How Does StilachiRAT Communicate with Remote Servers?

StilachiRAT uses multiple ports (53, 443, 16000) to communicate with remote servers, allowing cybercriminals to:

• Control infected devices remotely, executing commands like system reboots and registry manipulation.
• Clear logs and cover up their tracks.
• Perform other malicious actions that can compromise an entire network.

🛡️ How Can You Protect Against StilachiRAT and Similar Threats?

To prevent falling victim to StilachiRAT, follow these essential security tips:

• Download Software Only from Trusted Sources: Ensure the software you install comes from reliable providers.
• Enable Browser & OS Protection Features: Use features like safe links and attachments in Office 365 to defend against malicious files.
• Regularly Update Antivirus Software: Stay up to date with antivirus updates and patch any security vulnerabilities.
• Use Microsoft Defender or Other Security Tools: Additional protective tools, such as Microsoft Defender, help safeguard your system.

🔒 Further Recommendations for Protection

• Enable Detection and Prevention: Ensure that your security settings block potentially unwanted applications (PUAs).
• Activate Cloud-Delivered Protection: This provides real-time protection against evolving threats, especially those that are still emerging.
• Stay Updated: Microsoft continues to monitor StilachiRAT and will update users on any new vulnerabilities or defensive measures.

TL;DR:

⚠️ StilachiRAT is a remote access trojan targeting cryptocurrency wallets and credentials.
🔒 It steals data by monitoring browser configurations, saved passwords, and clipboard contents.
🛡️ Protect yourself by using trusted software, enabling OS and browser protections, and regularly updating your antivirus tools.
