MITRE ATT&CK
T1059.005 Visual Basic

The file is identified as malicious by ClamAV with the signature Win.Trojan.Pig-1. The presence of a legacy WordBasic AUTOCLOSE macro marker strongly suggests that the document is designed to automatically execute malicious code when opened. The document body contains strings that appear to be remnants of macro code or template text, including references to printer drivers and file paths.

Heuristics 2

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