MITRE ATT&CK
T1059.001 PowerShell T1218.005 System Binary Proxy Execution: Mshta

The presence of a high-severity Auto_Close VBA macro, coupled with a reference to mshta.exe, indicates that this PowerPoint file is designed to execute malicious code. The Auto_Close macro is configured to automatically run when the presentation is closed, likely initiating the download and execution of a second-stage payload from the embedded URL. The heuristic firings strongly suggest the use of mshta.exe for execution, which is a common technique for bypassing security controls.

Heuristics 5

  • Reference to mshta.exe high SC_STR_MSHTA
    Reference to mshta.exe
  • 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
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
