The file is a PowerPoint presentation containing VBA macros. The presence of an Auto_Close macro and VBA p-code auto-execution with Shell execution indicates that the macros are designed to run automatically upon opening or closing the presentation. The script likely downloads and executes a second-stage payload. No specific family could be identified.

Heuristics 3

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