MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is a PowerPoint presentation containing VBA macros, specifically triggering an Auto_Close macro with GetObject execution. This indicates the macro is designed to run automatically when the presentation is closed, likely to download and execute a second-stage payload. The presence of a large VBA macro and the Auto_Close execution are strong indicators of malicious intent, commonly used for initial access and payload delivery.

Heuristics 4

  • Auto_Close macro high OLE_VBA_AUTOCLOSE
    Auto_Close 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
