The critical OLE_VBA_SHELL heuristic indicates the presence of a Shell() call within the VBA macros. The Auto_Close macro is designed to execute automatically when the presentation is closed, and the VBA p-code auto-exec with execution tokens heuristic further confirms that the Auto_Close macro is configured to execute a Shell command. This suggests the macro is intended to download and execute a second-stage payload.

Heuristics 4

  • Shell() call in VBA critical OLE_VBA_SHELL
    Shell() call in VBA
  • Auto_Close macro high OLE_VBA_AUTOCLOSE
    Auto_Close 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
