The file is identified as a legacy WordBasic macro-virus by heuristics, specifically noting the 'TOOLSMACRO' marker. This indicates the presence of malicious macro code designed to execute automatically when the document is opened, likely to perform harmful actions. The file's age and the nature of the detected threat suggest a classic macro-based malware delivery mechanism.

  • Legacy WordBasic macro-virus markers high OLE_LEGACY_WORDBASIC_MACRO_VIRUS
    OLE Word document contains legacy WordBasic auto-execution macro markers such as AutoOpen plus ToolsMacro/MacroFile/fileMacro/globMacro or named historical macro-virus strings. These old Word 6/95 macro forms are not exposed as a modern VBA project, so normal VBA source extraction can miss them.
