Heuristics 4

  • Field QUOTE with ASCII-integer command payload critical OOXML_FIELD_QUOTE_ASCII_PAYLOAD
    QUOTE field in word/document.xml carries a decimal-ASCII byte sequence that decodes to a shell command referencing powershell
  • Word field-chain (SET/REF) co-located with DDE high OOXML_FIELD_SET_REF_CHAINING
    3 SET/REF variable pair(s) co-occur with DDE field(s) in word/document.xml
  • DDE field low OOXML_DDE
    DDE (Dynamic Data Exchange) field found in word/document.xml. The command does not reference a known-dangerous executable, but DDE can be abused for code execution.
  • 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.
