This sample is a confirmed MSIL Remote Access Trojan associated with the AsyncRAT / DcRAT malware family.
The file is heavily obfuscated and implements anti-debugging and sandbox evasion techniques.

Dynamic and static analysis show active command-and-control (C2) communication over abnormal ports, matching known AsyncRAT/DcRAT network patterns.
The sample contacts multiple domains proxied through Cloudflare infrastructure to conceal the true C2 origin.

VirusTotal detection confirms this file as malicious (50/71 vendors), with sandbox verdicts classifying it as a Trojan RAT with evasion capabilities.
This malware poses a high risk, enabling remote control, data exfiltration, and persistence on infected systems.
