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: 69. Detected as malicious: 44. Missed: 25. Coverage: 63.8%.

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

• T1222 – set file attributes
• T1497.001 – reference anti-VM strings targeting VMWare
• T1083 – check if directory exists
• T1083 – check if file exists
• T1082 – query environment variable
• T1560.002 – compress data using GZip in .NET
• T1497.001 – reference anti-VM strings targeting VirtualBox
• T1082 – Checks available memory
• T1071 – HTTP traffic contains suspicious features which may be indicative of malware related traffic
• T1071 – Looks up the external IP address
• T1071 – Reads from the memory of another process
• 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
• T1036 – Creates files with lurking names (e.g. Crack.exe)
• T1497 – Allocates memory with a write watch (potentially for evading sandboxes)
• 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
• T1562.001 – Creates guard pages, often used to prevent reverse engineering and debugging
• T1027 – Binary may include packed or crypted data
• 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
• 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 the volume information (name, serial number etc) of a device
• T1082 – Queries sensitive Operating System Information (via WMI, Win32_ComputerSystem, often done to detect virtual machines)
• T1082 – Queries the cryptographic machine GUID
• 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.
