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: 8. Missed: 65. Coverage: 11.0%.

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 (52.86% of behavior) indicates data harvesting, file encryption, or dropper behavior. The threat is actively searching for and manipulating files across the system.

• T1071 – Reads data out of its own binary image
• T1071 – The PE file contains an overlay
• T1070 – Deletes executed files from disk
• T1027 – The binary likely contains encrypted or compressed data
• T1027 – The binary contains an unknown PE section name indicative of packing
• T1027.002 – The binary likely contains encrypted or compressed data
• T1027.002 – The binary contains an unknown PE section name indicative of packing
• T1486 – Exhibits possible ransomware or wiper file modification behavior: overwrites_existing_files
• T1027.002 – PE file has section (not .text) which is very likely to contain packed code (zlib compression ratio < 0.011)

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.
