MITRE ATT&CK
T1059.005 Visual Basic

The sample is a malicious DOC file containing an XLM macro sheet, indicated by the OLE_XLM_AUTOOPEN heuristic. The document body presents a fake fax message detailing fraudulent wire transfer instructions, aligning with the SE_PAYMENT_REDIRECT_LURE heuristic. No scripts were extracted, but the presence of the XLM macro and the lure strongly suggest a business email compromise attack aimed at financial fraud.

Heuristics 3

  • Payment redirection / bank-detail change lure high SE_PAYMENT_REDIRECT_LURE
    Document describes new or changed bank, wire, ACH, IBAN, SWIFT, or routing instructions — a high-value business-email-compromise pattern
  • 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.
  • 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.
