The critical heuristic firing for a Shell() call in VBA, combined with the Auto_Close macro, indicates that this PowerPoint file is designed to execute arbitrary commands upon opening or closing. The VBA p-code auto-execution further supports this. While no specific URLs or hashes were extracted, the presence of these indicators strongly suggests a downloader or dropper functionality.

  • Auto_Close macro high OLE_VBA_AUTOCLOSE
    Auto_Close macro
  • VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC
