MITRE ATT&CK
T1559.001 Component Object Model Hijacking

The sample is an OLE document containing a risky embedded package identified as 'ole10native_00.bin'. This package is flagged as auto-executable, indicating it's likely designed to drop and run a secondary payload. The heuristic 'OFFICE_PACKAGE_RISKY_FILE' strongly suggests malicious intent related to the embedded artifact.

Heuristics 2

  • Ole10Native package drops an auto-executable payload critical OFFICE_PACKAGE_RISKY_FILE
    OLE Package displayName or fullPath ends in a directly auto-executable extension (a runnable binary or a script the default shell host runs on double-click). Embedding such a payload inside an Office document has no benign authoring use — it is a malware-delivery dropper.
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
