The file is an OLE document containing a legacy WordBasic AutoOpen macro, indicated by the OLE_LEGACY_WORDBASIC_AUTOEXEC heuristic. This macro is designed to execute automatically upon opening the document, suggesting an attempt to deliver a malicious payload. The ClamAV detection further supports its malicious nature. No specific family could be identified.

  • 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.
