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: 49. Missed: 24. Coverage: 67.1%.

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

Heavy cryptographic operations (93.31% of behavior) indicate potential ransomware, data encryption for exfiltration, or secure C2 communications. The malware is actively encrypting or decrypting sensitive data.

MITRE ATT&CK Mapping

• T1620 – load .NET assembly
• T1140 – decode data using Base64 in .NET
• T1027 – encode data using Base64
• T1539 – Touches a file containing cookies, possibly for information gathering
• T1564 – A process created a hidden window
• T1202 – Uses suspicious command line tools or Windows utilities
• T1202 – Uses Windows utilities for basic functionality
• T1112 – Installs itself for autorun at Windows startup
• 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
• T1082 – Checks available memory
• T1071 – Attempts to connect to a dead IP:Port
• T1071 – Yara detections observed in process dumps, payloads or dropped files
• T1071 – Reads data out of its own binary image
• T1071 – The PE file contains a suspicious PDB path
• T1071 – At least one IP Address, Domain, or File Name was found in a crypto call
• T1053 – Installs itself for autorun at Windows startup
• T1106 – Guard pages use detected – possible anti-debugging.
• T1059 – Executed a command line with /C or /R argument to terminate command shell on completion which can be used to hide execution
• T1064 – Executes batch files
• T1053 – Uses schtasks.exe or at.exe to add and modify task schedules
• T1036 – Creates files inside the user directory
• T1112 – Stores large binary data to the registry
• 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 – Binary may include packed or crypted data
• T1027.002 – .NET source code contains potential unpacker
• T1027.002 – PE file has an executable .text section which is very likely to contain packed code (zlib compression ratio < 0.3)
• T1027.002 – Binary may include packed or crypted data
• T1057 – Queries a list of all running processes
• T1083 – Reads ini files
• T1082 – Queries the volume information (name, serial number etc) of a device
• T1082 – Queries the cryptographic machine GUID
• T1082 – Checks the free space of harddrives

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.
