The file contains a critical ClamAV detection for Emotet and exhibits high-severity heuristics indicating the presence of VBA macros designed to auto-execute upon opening. The 'Document_Open' macro and 'CreateObject' call strongly suggest the execution of malicious code. The ClamAV signature 'Doc.Malware.Emotet-9762395-0' directly attributes this file to the Emotet family, which is known for its macro-based delivery of secondary payloads.

Heuristics 7

ClamAV: Doc.Malware.Emotet-9762395-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Malware.Emotet-9762395-0
Document_Open macro high OLE_VBA_DOCOPEN

Document_Open 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.
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.
