T1059.005 Visual Basic T1059.001 PowerShell T1204.002 Malicious File

The sample is a PowerPoint file containing VBA macros. The Auto_Close macro is configured to execute code using CreateObject and Shell() calls, indicating it attempts to download and execute a second-stage payload. The presence of a reference to Windows Script Host further supports this. The embedded URL, while marked as confirmed benign, is included as a potential IOC.

Heuristics 7

  • Shell() call in VBA critical OLE_VBA_SHELL
    Shell() call in VBA
  • Reference to Windows Script Host high SC_STR_WSCRIPT
    Reference to Windows Script Host
  • Auto_Close macro high OLE_VBA_AUTOCLOSE
    Auto_Close macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject 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.
    URL https://%69%69%69%69%69%69%69%69%69%69%69%69%69%69%69%69%69%69%69%69@j.mp/nwz2tmtjh5vibnmo53lk
