MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.005 Visual Basic

The file is detected as Win.Trojan.Cap-1 and contains legacy WordBasic macro virus markers, indicating malicious intent. The document body, presented as a legal bulletin, likely serves as a lure to encourage the opening of embedded malicious content. The embedded URL is suspicious and may be used for further payload delivery.

Heuristics 4

  • ClamAV: Win.Trojan.Cap-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Cap-1
  • Legacy WordBasic macro-virus markers high OLE_LEGACY_WORDBASIC_MACRO_VIRUS
    OLE Word document contains legacy WordBasic auto-execution macro markers such as AutoOpen plus ToolsMacro/MacroFile/fileMacro/globMacro or named historical macro-virus strings. These old Word 6/95 macro forms are not exposed as a modern VBA project, so normal VBA source extraction can miss them.
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • 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.
