MITRE ATT&CK
T1059.005 Visual Basic T1059.001 PowerShell

The file is a PowerPoint presentation containing VBA macros. The critical heuristic firing indicates a Shell() call within the VBA code, and the Auto_Close macro suggests this malicious code executes automatically when the presentation is closed. The VBA p-code auto-execution with execution tokens further confirms this. The primary intent appears to be the execution of arbitrary commands, likely for downloading and executing a secondary payload.

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
