MITRE ATT&CK
T1204.002 Malicious File: User Execution

The document is a malicious OLE file that contains a high-severity heuristic firing for an x86 GetPC stub, indicating potential shellcode execution. The large slack space anomaly further suggests the presence of embedded malicious content. The document body is unreadable, and no scripts were extracted, limiting further analysis of the specific payload or delivery mechanism.

Heuristics 2

  • x86 GetPC stub (CALL $+5; POP EAX) high SC_GETPC_CALL
    x86 GetPC stub (CALL $+5; POP EAX)
  • OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 84,481 bytes but its declared streams total only 16,536 bytes — 67,945 bytes (80%) 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).
