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 17+ hours, this malware remained undetected — a half-day window that permitted the adversary to complete initial execution, establish basic persistence, and perform initial system enumeration.

Global Detection Posture — Who Caught It, Who Missed It

VirusTotal engines: 73. Detected as malicious: 58. Missed: 15. Coverage: 79.5%.

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 – invoke .NET assembly method
• T1140 – decode data using Base64 in .NET
• T1620 – load .NET assembly
• T1564 – A process created a hidden window
• T1055 – Writes to the memory another process
• T1055 – Writes an executable to the memory of another process
• T1112 – Installs itself for autorun at Windows startup
• T1064 – A scripting utility was executed
• T1064 – Attempts to execute suspicious powershell command arguments
• T1027 – The binary likely contains encrypted or compressed data
• T1564.003 – A process created a hidden window
• T1027.002 – The binary likely contains encrypted or compressed data
• T1539 – Touches a file containing cookies, possibly for information gathering
• T1547 – Installs itself for autorun at Windows startup
• T1547.001 – Installs itself for autorun at Windows startup
• T1082 – Checks available memory
• T1071 – At least one IP Address, Domain, or File Name was found in a crypto call
• T1071 – Terminates another process
• T1071 – Yara detections observed in process dumps, payloads or dropped files
• T1071 – Reads data out of its own binary image
• T1071 – Reads from the memory of another process
• T1106 – Guard pages use detected – possible anti-debugging.
• T1059 – A scripting utility was executed
• T1059 – Attempts to execute suspicious powershell command arguments
• T1059 – A script or command line contains a long continuous string indicative of obfuscation
• T1059 – Executed a very long command line or script command which may be indicative of chained commands or obfuscation
• T1059.001 – Attempts to execute suspicious powershell command arguments

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.
