MITRE ATT&CK
T1059.005 Visual Basic

The sample is an OLE document containing a legacy WordBasic macro identified by the 'AutoOpen' marker. This macro is associated with the 'Lazy Virus' and is designed to infect existing documents or templates. The presence of this marker and the ClamAV detection strongly suggest malicious intent.

Heuristics 2

  • ClamAV: Win.Trojan.Lazy-3 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Lazy-3
  • 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.
