The file is a PowerPoint presentation containing VBA macros. A critical heuristic firing indicates the use of the Shell() function within a VBA macro, specifically within an Auto_Close macro named 'muthal'. This suggests the macro is designed to execute arbitrary commands upon closing the presentation. No specific malware family could be identified, and no external URLs or hashes were extracted.

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
