$ cat analysis.txt
=== THREAT ANALYSIS REPORT ===
Threat Name: Trojan:MSIL/barys!MTB
Classification:
Type:Trojan
Platform:MSIL
Family:barys
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 .NET (Microsoft Intermediate Language) platform, family barys

Summary:

Trojan:MSIL/barys!MTB is a concrete detection of a highly malicious Trojan, identified through machine learning behavioral analysis. It leverages sophisticated techniques such as API hooking, process injection (mshta, regsvr32, rundll32), and network manipulation (BITS, PowerShell) to establish persistence, evade detection, and facilitate remote control or data exfiltration.

Severity:
High
VDM Static Detection:
