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

The document body explicitly instructs the user to enable macros to view content, which is a common social engineering tactic. Heuristics indicate the presence of VBA macros that utilize the URLDownloadToFile API, suggesting the script's purpose is to download and execute a second-stage payload from a remote URL. The embedded URL http://misitiodetalento.com/ipod/logo.gif is suspicious and likely serves as the download source.

Heuristics 13

  • ClamAV: Doc.Downloader.Generic-6698421-0 critical CLAMAV_DETECTION

  • VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC
    Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.

  • 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.
  • 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.
