The presence of a high-severity heuristic for OLE_VBA_MACROS, specifically an Auto_Close macro that uses CreateObject and references Windows Script Host, indicates malicious VBA code execution. The Auto_Close macro is designed to run automatically when the presentation is closed, suggesting an attempt to download and execute a secondary payload. No specific IOCs were extracted, and the family is unknown due to the lack of further indicators.

Heuristics 5

  • Reference to Windows Script Host high SC_STR_WSCRIPT
    Reference to Windows Script Host
  • Auto_Close macro high OLE_VBA_AUTOCLOSE
    Auto_Close macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject 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
