MITRE ATT&CK
T1059.005 Visual Basic

The file is identified as a legacy Word document containing an AutoOpen macro, a common technique for executing malicious code upon document opening. The heuristic 'OLE_LEGACY_WORDBASIC_AUTOEXEC' confirms the presence of an auto-executing macro. The ClamAV detection 'Legacy.Trojan.Agent-446' strongly suggests a known malicious agent. The macro's 'Destroy$' command targeting 'C:\Windows\system\*.dll' indicates an intent to delete files, likely to disrupt system operations or remove competing malware.

    ClamAV detected this file as malware: Legacy.Trojan.Agent-446
  • 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.
