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: 60. Detected as malicious: 38. Missed: 22. Coverage: 63.3%.

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 (44.02% 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

• T1140 – decode data using Base64 in .NET
• T1620 – invoke .NET assembly method
• T1027 – encode data using Base64
• T1083 – check if file exists
• T1027 – encrypt data using AES via .NET
• 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.
• T1070.006 – Adversaries may modify file time attributes to hide new or changes to existing files.
• T1070 – Adversaries may delete or modify artifacts generated within systems to remove evidence of their presence or hinder defenses.
• T1027 – Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.
• T1027.002 – Adversaries may perform software packing or virtual machine software protection to conceal their code.
• T1059 – Sample may offer command line options, please run it with the command line option cookbook (it’s possible that the command line switches require additional characters like)
• T1059 – Sample might require command line arguments, analyze it with the command line cookbook
• T1574.002 – Tries to load missing DLLs
• T1497 – Allocates memory with a write watch (potentially for evading sandboxes)
• T1562.001 – Creates guard pages, often used to prevent reverse engineering and debugging
• T1027.002 – .NET source code contains method to dynamically call methods (often used by packers)
• T1027.002 – Binary may include packed or crypted data
• T1140 – .NET source code contains calls to encryption/decryption functions
• T1070.006 – Binary contains a suspicious time stamp
• T1027 – Binary may include packed or crypted data
• T1082 – Queries the volume information (name, serial number etc) of a device
• T1082 – Queries the cryptographic machine GUID
• T1082 – Reads software policies
• T1560 – .NET source code contains calls to encryption/decryption functions
• T1095 – Performs DNS lookups
• T1071 – Performs DNS lookups

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.
