MITRE ATT&CK

T1059.003 Windows Command Shell

The sample is an OLE document with a high slack space anomaly, indicating potential obfuscation or embedded malicious content. A 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 family.

OLE file is 66,720 bytes but its declared streams total only 21,151 bytes — 45,569 bytes (68%) 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).
