MITRE ATT&CK
T1059.005 Visual Basic

The sample is a legacy Word document containing a WordBasic auto-exec macro, indicated by the 'autoOpen' marker. This macro is designed to execute automatically upon opening, a common technique for initiating malicious actions. While the specific payload is not discernible from the provided evidence, the presence of an auto-exec macro strongly suggests a malicious intent, likely to download and execute further stages or perform other harmful actions.

Heuristics 2

    ClamAV detected this file as malware: Win.Trojan.Minimal-34
  • 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.
