MITRE ATT&CK
T1059.005 Visual Basic

The file contains legacy WordBasic macros, indicated by the 'AutoOpen' marker and the 'OLE_LEGACY_WORDBASIC_AUTOEXEC' heuristic. The document body text is designed to intimidate the user with threats of system destruction from a macro virus. The embedded URL is likely part of the lure or a potential command and control channel.

Heuristics 3

  • ClamAV: Win.Trojan.Trojan-455 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Trojan-455
  • 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.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
