The file is a PowerPoint presentation containing VBA macros. The Auto_Close macro is configured to execute a command using Windows Script Host, indicated by the SC_STR_WSCRIPT heuristic. The CreateObject call and VBA p-code auto-execution with Shell further suggest the macro is designed to launch an external process. The absence of specific URLs or file paths in the extracted evidence means the exact payload cannot be determined, but the intent is clearly to download and execute a second-stage payload.

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
