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

The file contains legacy WordBasic macro markers, specifically 'AutoOpen', which is a known indicator of malicious macro execution. The presence of 'C:\HAGGIS.DOC' suggests a potential payload location or name. ClamAV detection as Win.Trojan.Haggis-1 further supports the malicious classification.

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