The sample is a PowerPoint file containing VBA macros. The critical heuristic firing indicates a Shell() call within the VBA code, and the high severity heuristic confirms an Auto_Close macro is present. This suggests the macros are designed to execute arbitrary commands when the presentation is closed, likely to download and execute a second-stage payload. No specific family could be identified from the available evidence.

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
