MITRE ATT&CK
T1059.005 Visual Basic T1204.002 Malicious File

The file is a Microsoft Office document containing VBA macros, indicated by the OLE_VBA_MACROS heuristic. The OLE_VBA_CREATEOBJ heuristic suggests the macros are designed to execute code, likely to download and execute a secondary payload, as evidenced by the 'macros.bas' artifact. The embedded URL was confirmed as benign, and no other IOCs were extracted.

Heuristics 4

  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
  • Suspicious extracted artifact high 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.
  • 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.
