MITRE ATT&CK
T1059.005 Visual Basic

The file is identified as malicious by ClamAV with the signature Win.Trojan.Pig-1. A legacy WordBasic auto-execution macro marker (AUTOCLOSE) was detected, indicating the potential for automatic execution of malicious code upon opening the document. The document body contains obfuscated text and references to legacy WordBasic functions, further supporting the macro-based execution.

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.
