MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is a legacy Word document containing a WordBasic macro, indicated by the 'OLE_LEGACY_WORDBASIC_AUTOEXEC' heuristic firing with the 'AutoOpen' marker. The document body explicitly states 'This file infected with Macro.Word.X80 by FRiZER', suggesting a deliberate infection. The presence of an AutoOpen macro implies an attempt to execute malicious code automatically when the document is opened, consistent with a phishing attachment delivery method.

Heuristics 2

  • ClamAV: Legacy.Trojan.Agent-452 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Legacy.Trojan.Agent-452
  • 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.
