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

The sample is identified as malicious by ClamAV with the signature 'Doc.Downloader.Emotet-10001946-0', indicating it's a downloader for the Emotet family. Heuristics confirm the presence of VBA macros, including an AutoOpen macro and a CreateObject call, which are commonly used to execute malicious code. The VBA script, though truncated, suggests the execution of a second-stage payload, likely a downloader.

Heuristics 7

  • ClamAV: Doc.Downloader.Emotet-10001946-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Emotet-10001946-0
  • VBA macros detected medium 3 related findings OLE_VBA_MACROS
    Document contains VBA macro code
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call

    CreateObject(IKNEDz).Create# aiZQkM + "pow" + ZmENw_V + ThisDocument.zP1r39TU + Itozsaww + ThisDocument.kadvjs + ThisDocument.wDla3z_ + rcDCmlQF, Q_jN226, uFq_hzI, TYjBvwoJ
  • 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.
  • AutoOpen macro low OLE_VBA_AUTOOPEN
    AutoOpen macro
    Matched line in script
    autoopen( _
  • Legacy WordBasic auto-exec macro marker medium OLE_LEGACY_WORDBASIC_AUTOEXEC
    OLE Word document contains a legacy WordBasic auto-execution marker such as AutoOpen, but no modern VBA project was recovered and no stronger macro-virus family marker was present. This is analyst-facing evidence for old Word macro execution surface, not a downloader or parser-CVE attribution by itself.
  • 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.
