MITRE ATT&CK
T1059.005 Visual Basic

The file is identified as a legacy Word 6.0 document containing WordBasic auto-exec macros, specifically triggering on 'AutoClose'. This indicates an attempt to infect the user's Normal template, a common technique for macro-based malware propagation. The heuristic firings and document content strongly suggest this behavior.

Heuristics 2

  • ClamAV: Win.Trojan.Hiac-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Hiac-1
  • 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.
