Malware Insights

MITRE ATT&CK
T1059.005 Visual Basic

The file is identified as malicious by ClamAV and contains a marker for a legacy WordBasic auto-exec macro (AutoOpen). Although VBA extraction failed, the presence of the AutoOpen marker strongly suggests an attempt to run malicious code when the document is opened. The document body content is not indicative of a specific lure.

Heuristics 4

  • ClamAV: Doc.Malware.00536d-6705831-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Malware.00536d-6705831-0
  • 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
    olevba could not extract VBA macros (AssertionError); format-agnostic byte-level scans still ran. Likely legacy, encrypted, or malformed OLE/OOXML — re-scanning the same bytes will yield the same outcome.
  • 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.
