MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file contains VBA macros, including an auto-executing 'Document_Open' macro, which is a strong indicator of malicious intent. The presence of a 'CreateObject' call within the macro suggests it is designed to execute code or download additional payloads. ClamAV detection further confirms its malicious nature, identifying it as Emotet.

    ClamAV detected this file as malware: Doc.Malware.Emotet-9769425-0
  • 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

  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • Embedded URL info EMBEDDED_URL
