MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample contains a VBA macro that executes upon opening the document. This macro, specifically the Document_Open subroutine, appears to construct a URL by concatenating strings to form 'http://p://help.doc'. It then attempts to open this constructed document. The benign URLs extracted are likely unrelated to the malicious activity. The presence of a Document_Open macro and the construction of a URL strongly suggest a malicious intent to download and execute a secondary payload.

Heuristics 4

  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • 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.
    URL http://schemas.openxmlformats.org/drawingml/2006/main
    • http://schemas.openxmlformats.org/officeDocument/2006/bibliography
    • http://schemas.openxmlformats.org/officeDocument/2006/customXml
  • Macro capabilities present but unconfirmed info MACRO_CAPABILITY_UNCORROBORATED
    The document's VBA exposes execution capabilities (Shell/WScript/CreateObject/auto-exec) but nothing corroborates malicious intent — no obfuscation, memory-exec primitive, download+exec chain, encoded payload, LOLBin, DDE, AV hit, or suspicious URL. The verdict was capped at 'suspicious' so legitimate macro-heavy business documents are not flagged malicious on capability presence alone.
