MITRE ATT&CK
T1566.001 Spearphishing Attachment

The sample is a malicious Office document containing an OLE package that drops a batch file named 'LIST OF JOBS.PDF.bat'. This batch file is likely intended to be executed by the user, posing as a PDF document. The embedded URL was confirmed benign and no scripts were extracted.

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.
  • 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.
    URL http://schemas.openxmlformats.org/drawingml/2006/main In document text (OLE body)
