The file is a PowerPoint presentation containing VBA macros. Critical heuristic firings indicate the presence of a Shell() call within an Auto_Close macro, which is designed to execute code automatically when the presentation is closed. This suggests the macro is intended to download and execute a secondary payload. No specific family could be identified.

  • 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
