MITRE ATT&CK
T1059.005 Visual Basic T1059.001 PowerShell

The file is a PowerPoint presentation containing a VBA macro. The Auto_Open macro is present and configured to execute a command via ShellExecute. This indicates the macro is designed to run arbitrary code, likely downloading and executing a second-stage payload. The presence of 'macros.bas' suggests a script was extracted, which is the primary indicator of malicious behavior.

Heuristics 5

  • Reference to ShellExecute API high SC_STR_SHELLEXEC
    Reference to ShellExecute API
  • Auto_Open macro high OLE_VBA_AUTO
    Auto_Open 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
  • Suspicious extracted artifact medium EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
