The sample is an Excel 4.0 macro-enabled workbook that employs a common "enable content" lure. Embedded XLM macros are present, indicated by the `OLE_XLM_AUTOOPEN` heuristic. These macros likely attempt to download and execute a second-stage payload from one of the two provided URLs, as suggested by the `OLE_XLM_AUTOOPEN_PAYLOAD_LURE` and `EMBEDDED_URL` firings. The `rundll32.exe` command within the DOC BODY further suggests execution of a downloaded payload.

Heuristics 4

  • XLM Auto_Open workbook with payload URL or enable-content lure critical OLE_XLM_AUTOOPEN_PAYLOAD_LURE
    Workbook contains an Excel 4.0 macro sheet with Auto_Open / Auto_Close and also exposes a payload URL or enable-content lure in the OLE bytes. This combination is a high-confidence XLM downloader/social-engineering pattern even when formula recovery cannot decode the full macro chain.
  • Excel 4.0 (XLM) macro sheet present medium OLE_XLM_AUTOOPEN
    Workbook contains an Excel 4.0 macro sheet sub-stream — XLM is rarely seen in modern legitimate workbooks and was a major Office malware vector during 2020-2022.
  • Macro/content-enable lure medium SE_ENABLE_LURE
    Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
  • 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.
