=== THREAT ANALYSIS REPORT ===
Threat Name: /HTML/Obfuse.PC!MTB
Classification:
Detection Type:Behavioral/ML
Suffix:!MTB
Detected via machine learning and behavioral analysis
Detection Method:Behavioral
Confidence:High
False-Positive Risk:Low

Machine learning behavioral analysis detected malicious patterns

Summary:

This is an obfuscated HTML-based threat detected by behavioral analysis. It leverages scripting (likely VBScript/JScript) to download and execute secondary malicious payloads, such as a JavaScript file, from a remote HTTP source, potentially using legitimate Windows binaries like `mshta.exe` or `regsvr32.exe` for execution and persistence.

Severity:
Medium
