T1059.001 PowerShell
T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The sample is identified as malicious by ClamAV with a signature for Emotet. Critical heuristics indicate the presence of VBA macros that call the Shell() function and reference PowerShell. The AutoClose macro is also present, suggesting execution upon document closure. These factors strongly indicate that the VBA code is designed to download and execute a secondary payload, a common Emotet behavior.

Legacy WordBasic auto-exec macro marker medium OLE_LEGACY_WORDBASIC_AUTOEXECOLE Word document contains a legacy WordBasic auto-execution marker such as AutoOpen, but no modern VBA project was recovered and no stronger macro-virus family marker was present. This is analyst-facing evidence for old Word macro execution surface, not a downloader or parser-CVE attribution by itself.
-
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGEOne 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.
-
Embedded URL info EMBEDDED_URLOne 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 http://schemas.openxmlformats.org/drawingml/2006/main In document text (OLE body)

Obfuscation or payload:
likely
44 of 77 identifiers look randomly generated (e.g. 'VQPkvkdTzhR') — consistent with name-mangling obfuscation.
