Trojan:JS/Obfuse.HNAZ!MTB - Windows Defender Threat Analysis

$ cat analysis.txt
=== THREAT ANALYSIS REPORT ===
Threat Name: Trojan:JS/Obfuse.HNAZ!MTB
Classification:
Type:Trojan
Platform:JS
Family:Obfuse
Detection Type:Concrete
Known malware family with identified signatures
Variant:HNAZ
Specific signature variant within the malware family
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 JavaScript platform, family Obfuse

Summary:

This is an obfuscated JavaScript trojan detected by machine learning behavioral analysis, indicating a high-confidence threat. It possesses advanced capabilities for execution via legitimate system utilities (mshta, regsvr32, rundll32, PowerShell), establishing persistence through scheduled tasks and BITS jobs, API hooking for evasion, remote file manipulation, and data encoding, signaling a comprehensive attack framework.

Severity:
Critical

Remediation Steps:
Immediately isolate the affected system, remove the detected threat, and perform a full system scan with updated security software. Investigate for any established persistence mechanisms (e.g., scheduled tasks, registry entries) and signs of further compromise such as C2 communication or data exfiltration. Reimaging the system is highly recommended to ensure complete eradication.
