MITRE ATT&CK
T1059.005 Visual Basic

The file is a legacy Word document containing a WordBasic AUTOOPEN macro, a known indicator of malicious activity. The ClamAV heuristic also flags it as Win.Trojan.Pig-2. The macro's specific function is not detailed, but its presence strongly suggests an attempt to execute arbitrary code.

Heuristics 2

  • ClamAV: Win.Trojan.Pig-2 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Pig-2
  • 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.
