MITRE ATT&CK
T1059.001 PowerShell T1566.001 Spearphishing Attachment

The sample is a PowerPoint file containing VBA macros, including an Auto_Open macro that utilizes GetObject. Heuristics indicate a reference to PowerShell and the execution of VBA p-code. The Auto_Open macro likely initiates the execution of PowerShell commands, suggesting a downloader or initial execution stage for a malicious payload.

Heuristics 6

  • Reference to PowerShell high SC_STR_POWERSHELL
    Reference to PowerShell
  • Auto_Open macro high OLE_VBA_AUTO
    Auto_Open macro
  • GetObject call high OLE_VBA_GETOBJ
    GetObject call
  • 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.
