Overview

This video explains how to detect if a PC is compromised by modern malware, specifically Remote Access Tools (RATs). It demonstrates how malware operates subtly without obvious signs and how to identify it by analyzing network activity, process execution, and encoded scripts. The video also provides practical tips for securing a PC by disabling certain functionalities and recommends tools for malware analysis.

Key takeaways

• Subtle Malware: Modern malware, including RATs, typically operates silently without obvious indicators like unusual noises or error messages.
• Network Activity Analysis: Monitoring network connections is crucial for identifying potential compromises. Unusual connections to unknown servers or IP addresses can indicate malicious activity.
• Process Monitoring: Examining running processes can reveal suspicious activity. While system processes like svcHost.exe, wscript.exe, PowerShell, and Command Prompt are normal, their execution of encoded scripts (like Base64) or unusual commands can be a sign of malware.
• Encoded Scripts: Malware often uses encoded scripts (e.g., Base64) to hide its true purpose. Decoding these scripts can reveal the actual commands being executed, such as downloading further malicious payloads.
• Command and Control (C2): A compromised computer often connects to a Command and Control (C2) server, which is used by attackers to remotely control the victim's system. Identifying the IP address and port of this connection is key.
• Weaponized System Processes: Attackers frequently "weaponize" legitimate Windows processes like PowerShell, WScript, and JavaScript to execute malicious code, making detection harder as the process names appear safe.
• Securing Your PC: To enhance security, consider disabling JavaScript execution, restricting PowerShell script execution, and generally locking down Windows vulnerabilities that are often exploited.
• Tools for Analysis: Tools like TCPView from Sysinternals (Microsoft) are valuable for monitoring network connections and identifying suspicious activity. Platforms like VirusTotal can help analyze suspicious IP addresses.
