=== THREAT ANALYSIS REPORT ===
Threat Name: DDoS:Linux/Mirai.YC!MTB
Classification:
Type:DDoS
Platform:Linux
Family:Mirai
Detection Type:Concrete
Known malware family with identified signatures
Variant:YC
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: DDoS for Linux platform, family Mirai

Summary:

This is a confirmed Mirai botnet variant targeting Linux systems. It uses anti-honeypot mechanisms to evade detection and downloads/executes malicious payloads, likely to enslave devices for Distributed Denial of Service (DDoS) attacks.

Severity:
Critical
VDM Static Detection:
No specific strings found for this threat

Remediation Steps:
Immediately isolate any infected Linux systems. Perform a thorough scan to detect and remove the Mirai malware, patch all system vulnerabilities, enforce strong access controls and unique, complex passwords, and implement robust network segmentation with egress filtering to block communication with Mirai Command and Control (C2) servers.
