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

The file is a legacy Word document containing a WordBasic macro named 'AutoOpen', which is a known auto-execution marker. This heuristic, combined with the ClamAV detection of 'Win.Trojan.Archie-1', strongly suggests the document is designed to execute malicious code when opened, likely as a spearphishing attachment. The document body contains text related to viruses and macro execution, further supporting this conclusion.

Heuristics 2

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