MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample contains VBA macros, specifically a Document_Open macro that utilizes CreateObject, indicating malicious intent. ClamAV detection confirms this as Emotet. The obfuscated VBA code likely attempts to download and execute a secondary payload, a common Emotet tactic.

Heuristics 6

ClamAV: Doc.Malware.Emotet-9784450-1 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Malware.Emotet-9784450-1
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.
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.
