Heuristics 3

  • Reference to PowerShell high SC_STR_POWERSHELL
    Reference to PowerShell
  • OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 93,568 bytes but its declared streams total only 51,411 bytes — 42,157 bytes (45%) 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).
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
