MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The file contains VBA macros, specifically a Document_Open macro that uses CreateObject to execute obfuscated code. This behavior is characteristic of Emotet, which often uses macros to download and execute further stages. The obfuscated VBA script likely attempts to download and execute a second-stage payload, aligning with Emotet's typical infection chain.

Heuristics 6

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.
