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

The sample is an Excel spreadsheet containing VBA macros, specifically a Workbook_Open macro that is designed to execute automatically. The document body presents a fake payment order form, indicating a social engineering lure for financial fraud. The Workbook_Open macro is the primary mechanism for executing the malicious payload.

Heuristics 3

  • Workbook_Open macro high OLE_VBA_WBOPEN
    Workbook_Open macro
  • 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
