Heuristics 2

  • OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 158,736 bytes but its declared streams total only 43,339 bytes — 115,397 bytes (73%) 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).
  • VBA project contains no executable statements info OLE_VBA_MACROS
    Document contains a VBA project, but extracted modules only contain attributes/options/comments and no executable statements.
