MITRE ATT&CK
T1559 Component Object Model Hijacking T1559.001 Component Object Model Hijacking: DLL Side-Loading

The sample contains an embedded OLE object which is flagged as a risky file type that drops an auto-executable payload, specifically identified as a JAR file. This indicates the document is likely a dropper for a secondary malicious payload. The presence of the OLE object and the nature of the dropped artifact strongly suggest an attempt to execute arbitrary code.

Heuristics 4

  • 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.
  • Embedded OLE object medium OOXML_OLE_OBJECT
    Document contains an embedded OLE object
  • 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.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
