MITRE ATT&CK

T1059.005 Visual Basic

The sample was detected as Emotet by ClamAV and exhibits high-severity heuristics for VBA macros, including CreateObject and auto-execution via Document_Open. The obfuscated VBA script likely attempts to download and execute a second-stage payload, potentially using PowerShell, which is 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.
