MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample is a malicious Word document containing a Document_Open VBA macro. This macro is designed to copy content and then potentially execute a secondary payload by creating a file in the user's template path. The macro attempts to write registry keys related to VBA security settings, specifically 'HKCU\Software\Microsoft\Office\16.0\Word\Security\VBAWarnings' and 'HKCU\Software\Microsoft\Office\16.0\Word\Security\AccessVBOM', likely to bypass security prompts and enable macro execution. The presence of the EMF object and the Document_Open macro strongly suggest an attempt to exploit user interaction for malicious purposes.

Heuristics 5

Office EPRINT stream contains EMF object high CVE related OLE_EPRINT_EMF_OBJECT

OLE ObjectPool contains an EPRINT stream with EMF data. This is rare in normal documents and is CVE-2007-3893/MS07-046-family evidence when paired with Office exploit payload anomalies, but the malformed EMF record is not proven by this rule alone.
Document_Open macro high OLE_VBA_DOCOPEN

Document_Open macro
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
Suspicious extracted artifact info 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.
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.
