$ cat analysis.txt
=== THREAT ANALYSIS REPORT ===
Threat Name: Trojan:AndroidOS/Coper!rfn
Classification:
Type:Trojan
Platform:AndroidOS
Family:Coper
Detection Type:Concrete
Known malware family with identified signatures
Suffix:!rfn
Specific ransomware family name
Confidence:Very High
False-Positive Risk:Low

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

Summary:

Trojan:AndroidOS/Coper!rfn is a concrete detection of a malicious trojan, primarily identified as an Android threat but found with Windows Defender. The associated technical analysis reveals strings indicative of sophisticated Windows-specific capabilities such as process hooking, persistence via scheduled tasks and BITS jobs, remote code execution through rundll32/PowerShell, and file manipulation. This suggests the trojan aims to gain deep control, establish persistence, and execute arbitrary commands on a compromised system, potentially as part of a multi-platform attack or if interacting with a Windows environment.
