The file is a PowerPoint presentation containing a significant amount of VBA macro code. Heuristics indicate the presence of an Auto_Close macro and a critical finding of a Shell() call within the VBA code. This suggests the macro is designed to execute arbitrary commands upon closing the presentation, likely for downloading and executing a secondary payload. No specific family could be identified, and no external IOCs were extracted.

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
