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 1+ 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: 55. Missed: 18. Coverage: 75.3%.

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

Intensive file system activity (49.28% of behavior) indicates data harvesting, file encryption, or dropper behavior. The threat is actively searching for and manipulating files across the system.

MITRE ATT&CK Mapping

• T1222 – set file attributes
• T1083 – check if file exists
• T1033 – get session user name
• T1087 – get session user name
• T1497.001 – reference anti-VM strings targeting Xen
• T1497.001 – reference anti-VM strings targeting VirtualBox
• T1082 – query environment variable
• T1083 – check if directory exists
• T1497.001 – reference anti-VM strings targeting VMWare
• T1560.002 – compress data using GZip in .NET
• T1033 – get session integrity level
• T1027 – The binary likely contains encrypted or compressed data
• T1027.002 – The binary likely contains encrypted or compressed data
• T1082 – Checks available memory
• T1071 – HTTP traffic contains suspicious features which may be indicative of malware related traffic
• T1071 – Reads from the memory of another process
• T1071 – Looks up the external IP address
• T1106 – Guard pages use detected – possible anti-debugging.
• T1047 – Queries sensitive Operating System Information (via WMI, Win32_ComputerSystem, often done to detect virtual machines)
• T1542.003 – May use bcdedit to modify the Windows boot settings
• T1497 – Queries sensitive Operating System Information (via WMI, Win32_ComputerSystem, often done to detect virtual machines)
• T1497 – Checks if the current process is being debugged
• 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 – PE file has section (not .text) which is very likely to contain packed code (zlib compression ratio < 0.011)
• T1518.001 – Queries sensitive Operating System Information (via WMI, Win32_ComputerSystem, often done to detect virtual machines)
• T1518.001 – Checks if the current process is being debugged
• T1518.001 – Check if machine is in data center or colocation facility
• T1016 – Checks the online ip address of the machine
• T1082 – Queries sensitive Operating System Information (via WMI, Win32_ComputerSystem, often done to detect virtual machines)
• T1082 – Queries the cryptographic machine GUID
• T1082 – Queries the volume information (name, serial number etc) of a device
• T1105 – Downloads files from webservers via HTTP
• T1095 – Downloads files from webservers via HTTP
• T1071 – Downloads files from webservers via HTTP

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.
