This PowerPoint file contains a large VBA macro, indicated by the OLE_VBA_MACROS heuristic. The Auto_Close macro is present and configured to execute code via the Shell() function, as flagged by OLE_VBA_SHELL and OLE_VBA_PCODE_AUTOEXEC_EXEC. The specific VBA macro file 'macros.bas' was extracted. The macro's intent is to execute arbitrary commands, likely to download and run a second-stage payload, but the exact command is not reconstructible from the provided evidence.

Heuristics 5

  • 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
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
