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

The file is identified as malicious by ClamAV with the signature 'Doc.Malware.Emotet-9781039-0'. Heuristics indicate the presence of a Document_Open VBA macro that utilizes CreateObject, suggesting it's designed to execute arbitrary code. The VBA code is heavily obfuscated, but the overall pattern is consistent with Emotet's typical behavior of downloading and executing further malicious payloads.

Heuristics 6

  • ClamAV: Doc.Malware.Emotet-9781039-0 critical CLAMAV_DETECTION

    Document_Open macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call

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