T1204 Malicious File
T1204.002 Malicious File: User Execution
The sample is a malicious OLE document with a significant amount of slack space, indicating potential obfuscation or embedded malicious content. The presence of an x86 GetPC stub heuristic firing suggests the use of shellcode. While no specific exploit or payload is directly identified, the combination of these factors strongly points to a document designed to exploit a vulnerability upon opening.

x86 GetPC stub (CALL $+5; POP EAX) high SC_GETPC_CALLx86 GetPC stub (CALL $+5; POP EAX)

OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 351,233 bytes but its declared streams total only 16,536 bytes — 334,697 bytes (95%) 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).
