MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The sample contains VBA macros, specifically a Document_Open macro that utilizes CreateObject. This is a common technique for Emotet to download and execute additional malicious payloads. The ClamAV detection also strongly suggests Emotet. The obfuscated VBA code and the use of CreateObject indicate an attempt to dynamically instantiate objects for malicious purposes, likely to fetch and run a second-stage payload.

Heuristics 6

  • ClamAV: Doc.Malware.Emotet-9785300-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Malware.Emotet-9785300-0
  • 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.
  • 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.
