Trojan:Win64/Meterpreter.E - Windows Defender Threat Analysis

$ cat analysis.txt
=== THREAT ANALYSIS REPORT ===
Threat Name: Trojan:Win64/Meterpreter.E
Classification:
Type:Trojan
Platform:Win64
Family:Meterpreter
Detection Type:Concrete
Known malware family with identified signatures
Variant:E
Specific signature variant within the malware family
Confidence:Very High
False-Positive Risk:Low

Concrete signature match: Trojan - Appears legitimate but performs malicious actions for 64-bit Windows platform, family Meterpreter

Summary:

This is a concrete detection of Trojan:Win64/Meterpreter.E, a sophisticated post-exploitation framework. It deploys shellcode, uses process injection (VirtualAllocEx, WriteProcessMemory), and establishes a reverse shell via network communication, granting remote attackers full control over the compromised system for data exfiltration and further malicious activities.

Severity:
Critical
VDM Static Detection:
