=== 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:

This is a sophisticated Trojan from the MSIL/barys family, detected concretely via machine learning behavioral analysis. It employs various techniques like process injection, API hooking, and system utility abuse (BITS, PowerShell, scheduled tasks) to establish persistence, manipulate network settings, and exfiltrate data. Originating from a known malicious GitHub repository and actively distributed via web downloads, it poses a significant and advanced threat.

Severity:
Critical

Remediation Steps:
Immediately isolate the infected system and initiate a full system scan with an updated EDR/antivirus solution. Block the identified SHA256 hash (9691ddc08712445cba00656b4d7965eee2c045ebbcabe81c0a1f21f5357a953b) and any identified command and control (C2) infrastructure on all network and endpoint security controls. Conduct a forensic investigation to identify the infection vector, remove all persistence mechanisms, and ensure no further compromise or data exfiltration occurred.
