T1204.002 Malicious File
The document is a Microsoft Word file exhibiting a high-severity OLE slack anomaly, indicating a potentially packed or obfuscated payload. A high-severity heuristic also fired for an x86 GetPC stub, commonly used in shellcode to locate its own position in memory. These indicators suggest the document is designed to exploit a vulnerability and execute arbitrary code, though no specific exploit or family can be confidently identified.

OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 119,297 bytes but its declared streams total only 16,536 bytes — 102,761 bytes (86%) 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).
