Heuristics 3

  • MSCOMCTL.ListView — CVE-2012-0158 high CVE likely CVE_2012_0158
    MSCOMCTL.ListView — CVE-2012-0158
  • OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 265,408 bytes but its declared streams total only 46,065 bytes — 219,343 bytes (83%) 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).
  • OLE file has appended executable-looking payload bytes high OLE_APPENDED_PAYLOAD
    OLE compound file contains a large high-entropy region beyond the declared major streams and that region includes shellcode, PE, or loader API markers. This is a payload-carrier signal, not a specific CVE attribution by itself.
