=== THREAT ANALYSIS REPORT ===
Threat Name: Trojan:JS/Redirector.ZIJ!MTB
Classification:
Type:Trojan
Platform:JS
Family:Redirector
Detection Type:Concrete
Known malware family with identified signatures
Variant:ZIJ
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 Redirector

Summary:

Trojan:JS/Redirector.ZIJ!MTB is a sophisticated JavaScript-based trojan identified through machine learning behavioral analysis. Beyond its redirector function, it leverages advanced techniques like process hooking, abusing legitimate Windows utilities (mshta, rundll32, PowerShell, BITS), and creating scheduled tasks to establish persistence, evade detection, and execute arbitrary code, posing a significant risk for further system compromise.
