Trojan:Linux/SAgnt!MTB - Windows Defender Threat Analysis

$ cat analysis.txt
=== THREAT ANALYSIS REPORT ===
Threat Name: Trojan:Linux/SAgnt!MTB
Classification:
Type:Trojan
Platform:Linux
Family:SAgnt
Detection Type:Concrete
Known malware family with identified signatures
Suffix:!MTB
Detected via machine learning and behavioral analysis
Detection Method:Behavioral
Confidence:Very High
False-Positive Risk:Low

Concrete signature match: Trojan - Appears legitimate but performs malicious actions for Linux platform, family SAgnt

Summary:

This is a Trojan detected on a Windows system using machine learning behavioral analysis (!MTB) from the SAgnt family, despite its naming suggesting a Linux platform. It exhibits behaviors indicative of abusing legitimate Windows utilities such as mshta, rundll32, PowerShell, and BITS for execution, persistence, and network communications. The threat also shows intent to perform hooking, data encoding, file operations, and potentially bypass security measures, indicating sophisticated malicious activity.

Severity:
High

Remediation Steps:
Immediately isolate the affected system to prevent further compromise. Conduct a thorough antivirus scan to remove all detected components and investigate for persistence mechanisms, such as scheduled tasks, modified registry entries, or startup items. Review system logs for suspicious activity involving Windows utilities like PowerShell, rundll32, or mshta, and ensure all operating system and applications are patched; consider re-imaging the system if complete eradication cannot be confirmed.
