MITRE ATT&CK

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

The file contains VBA macros, specifically a Document_Open macro that uses CreateObject to execute code. The ClamAV detection explicitly names this as 'Doc.Downloader.Emotet-9784039-0', indicating its role as a downloader for the Emotet family. The obfuscated document body text likely contains further obfuscated instructions or lures, but the primary malicious activity is confirmed by the macro execution and the ClamAV signature.

Heuristics 7

ClamAV: Doc.Downloader.Emotet-9784039-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Downloader.Emotet-9784039-0
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.
