=== THREAT ANALYSIS REPORT ===
Threat Name: Trojan:VBS/Malgent!MSR
Classification:
Type:Trojan
Platform:VBS
Family:Malgent
Detection Type:Concrete
Known malware family with identified signatures
Suffix:!MSR
High-priority threat flagged by Microsoft Security Response
Confidence:Very High
False-Positive Risk:Low

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

Summary:

This is a VBScript-based Trojan (Malgent family) that acts as a downloader and dropper. It attempts to fetch and execute multiple malicious executables (e.g., 'boosting.exe', 'quotation.exe', 'win.exe', 'Ds.exe') from various suspicious URLs and IP addresses, often dropping them into user directories like Desktop, AppData, or Temp for execution and persistence. The script utilizes string obfuscation to evade detection.

Severity:
Critical
