Executive Overview — What We’re Dealing With

This specimen has persisted long enough to matter. Human experts classified it as Malware, and the telemetry confirms a capable, evasive Trojan with real impact potential.

Extended Dwell Time Impact

For 7+ minutes, this malware was rapidly detected — demonstrating excellent security controls that intercepted the threat during initial execution phases, severely limiting adversary capabilities.

Global Detection Posture — Who Caught It, Who Missed It

VirusTotal engines: 72. Detected as malicious: 52. Missed: 20. Coverage: 72.2%.

Why it matters: if any endpoint relies solely on a missed engine, this malware can operate with zero alerts. Prevention‑first controls close that gap regardless of signature lag.

MITRE ATT&CK Mapping

• T1620 – load .NET assembly
• T1129 – link function at runtime on Windows
• T1140 – decode data using Base64 in .NET
• T1562 – Tries to unhook or modify Windows functions monitored by CAPE
• T1562.001 – Tries to unhook or modify Windows functions monitored by CAPE
• T1027 – The binary likely contains encrypted or compressed data
• T1027.002 – The binary likely contains encrypted or compressed data
• T1539 – Touches a file containing cookies, possibly for information gathering
• T1082 – Checks available memory
• T1071 – Terminates another process

Following the Trail — Network & DNS Activity

Outbound activity leans on reputable infrastructure (e.g., CDNs, cloud endpoints) to blend in. TLS sessions and
HTTP calls show routine beaconing and IP‑lookup behavior that can masquerade as normal browsing.

Hunting tip: alert on unknown binaries initiating TLS to IP‑lookup services or unusual CDN endpoints — especially early in execution.
