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 2+ hours, this malware remained undetected — a limited but sufficient window for the adversary to complete initial execution and establish basic system access.

Global Detection Posture — Who Caught It, Who Missed It

VirusTotal engines: 73. Detected as malicious: 53. Missed: 20. Coverage: 72.6%.

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.

Behavioral Storyline — How the Malware Operates

Dominant system-level operations (39.68% of behavior) suggest this malware performs deep system reconnaissance, privilege escalation, or core OS manipulation. It’s actively probing system defenses and attempting to gain administrative control.

MITRE ATT&CK Mapping

• T1027.004 – compile .NET assembly
• T1027.004 – compile CSharp in .NET
• T1620 – invoke .NET assembly method
• T1016 – get domain information
• T1082 – An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, hotfixes, service packs, and architecture.
• T1071 – Adversaries may communicate using application layer protocols to avoid detection/network filtering by blending in with existing traffic.
• T1106 – Adversaries may interact with the native OS application programming interface (API) to execute behaviors.
• T1055 – Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges.
• T1036 – Creates files inside the user directory
• T1562.001 – Creates guard pages, often used to prevent reverse engineering and debugging
• T1497 – Contains long sleeps (>= 3 min)
• T1497 – May sleep (evasive loops) to hinder dynamic analysis
• T1070.006 – Binary contains a suspicious time stamp
• T1082 – Reads software policies
• T1082 – Queries the volume information (name, serial number etc) of a device
• T1036 – Creates files inside the user directory
• T1562.001 – Creates guard pages, often used to prevent reverse engineering and debugging
• T1497 – Contains long sleeps (>= 3 min)
• T1497 – May sleep (evasive loops) to hinder dynamic analysis
• T1070.006 – Binary contains a suspicious time stamp
• T1082 – Reads software policies
• T1082 – Queries the volume information (name, serial number etc) of a device

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.
