MITRE ATT&CK
T1059.003 Command and Scripting Interpreter: Windows Command Shell

The sample is an OLE document with a high slack anomaly, indicating potential obfuscation or embedded malicious content. A high-severity heuristic firing for CreateProcess API suggests the document attempts to launch an external process. No document body or script content was available for further analysis, limiting the ability to determine the exact payload or delivery mechanism.

Heuristics 2

  • 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 63,648 bytes but its declared streams total only 21,151 bytes — 42,497 bytes (67%) 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).
