The file is a Microsoft Word document containing VBA macros. The 'CreateObject' heuristic firing and the presence of a 'macros.bas' file indicate that the macros are likely designed to execute arbitrary code. The document body contains what appears to be obfuscated text, further suggesting malicious intent. The macros likely download and execute a second-stage payload, although the specific mechanism is not fully detailed in the provided heuristics.

Heuristics 4

  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
  • Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • 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.
