MITRE ATT&CK
T1059.005 Visual Basic

The file is a Microsoft Word document containing embedded VBA macros. The presence of a 'Document_Open' macro, combined with a 'GetObject' call and VBA p-code execution, indicates an attempt to automatically run malicious code when the document is opened. No specific malware family could be identified, and no external IOCs were extracted.

Heuristics 5

  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • GetObject call high OLE_VBA_GETOBJ
    GetObject call
  • VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC
    Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
  • 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
