MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a critical heuristic firing for Doc.Malware.00536d-6705955-0. A legacy WordBasic auto-exec macro marker (AutoOpen) was detected, suggesting an attempt to automatically execute code upon opening. Although VBA extraction failed, the presence of an embedded URL and the overall malicious verdict indicate a likely phishing attempt via attachment.

Heuristics 4

  • ClamAV: Doc.Malware.00536d-6705955-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Malware.00536d-6705955-0
  • 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.
  • Unsupported Office format for VBA extraction info OFFICE_FORMAT_UNSUPPORTED
    The Analyzer could not extract VBA macros: the document may be legacy, encrypted or malformed.
  • 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.
