The sample is a PowerPoint file containing VBA macros. The critical heuristic 'OLE_VBA_SHELL' indicates the presence of a Shell() call within the VBA code, which is often used to execute arbitrary commands. The 'OLE_VBA_AUTOCLOSE' and 'OLE_VBA_PCODE_AUTOEXEC_EXEC' heuristics further suggest that this malicious code is designed to run automatically when the document is opened or closed. The specific command executed by Shell() could not be determined from the provided evidence, but the intent is to run an external process.

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
