MITRE ATT&CK
T1059.005 Visual Basic T1059.003 Windows Command Shell

The sample is a malicious PowerPoint file containing VBA macros. The Auto_Close macro is configured to execute code via Shell, and a reference to mshta.exe was detected. This indicates the macro is likely intended to download and execute a second-stage payload. No specific family could be identified.

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.
