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

The file is an Excel spreadsheet containing a Workbook_Open VBA macro, which is a common technique for executing malicious code upon opening. The macro's structure suggests it is designed to process commands for creating or modifying other files, potentially downloading and executing a second-stage payload. The presence of a Workbook_Open macro and the general structure of the VBA code strongly indicate a malicious intent, likely delivered as a spearphishing attachment.

Heuristics 3

  • Workbook_Open macro high OLE_VBA_WBOPEN
    Workbook_Open macro
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • 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.
