MITRE ATT&CK
T1059.005 Visual Basic

The file is a legacy Word document containing a WordBasic auto-execute macro, indicated by the OLE_LEGACY_WORDBASIC_AUTOEXEC heuristic. ClamAV also detected it as malware. The presence of the 'aUTOoPen' marker suggests the macro is intended to run automatically when the document is opened, likely to perform malicious actions.

Heuristics 2

  • ClamAV: Doc.Trojan.MinSize-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.MinSize-1
  • 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.
