The sample is a PowerPoint file containing VBA macros, with a critical heuristic firing for a Shell() call. The Auto_Close macro is present, indicating that the malicious code executes when the presentation is closed. The VBA p-code indicates an auto-execution with execution tokens, specifically tied to the Auto_Close event and Shell execution. No specific IOCs like URLs or hashes were extracted, but the presence of the Shell() call strongly suggests the execution of arbitrary commands.

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
