MITRE ATT&CK
T1059.001 PowerShell

The presence of a CreateProcess API reference and a significant slack space anomaly in the OLE document suggests an attempt to execute code. The embedded URL, although benign, is present in the document body. The document body itself contains references to embedded objects like Excel and PowerPoint, which could be used to deliver malicious content.

Heuristics 3

  • Reference to CreateProcess API high SC_STR_CREATEPROCESS
    Reference to CreateProcess API
  • OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 117,760 bytes but its declared streams total only 31,351 bytes — 86,409 bytes (73%) live in unallocated sector slack. This is the canonical hiding place for pre-macro-era Office exploit payloads (XOR-encoded shellcode reached via a parser pointer-corruption bug in the document structure).
  • 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.
