MITRE ATT&CK
T1059.005 Visual Basic

The critical ClamAV heuristic indicates the file is Win.Trojan.Clock-4. The presence of a legacy WordBasic auto-exec macro (AutoOpen) suggests the document is designed to automatically run malicious code upon opening. The document body content appears to be unrelated boilerplate text, likely used to obfuscate the malicious intent.

Heuristics 2

  • ClamAV: Win.Trojan.Clock-4 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Clock-4
  • 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.
