MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a large number of external links, many of which are structured as a link farm. The document body presents itself as a 'Nashville tennessee visitor guide', a common lure to encourage users to click on embedded links. The primary malicious link identified is http://mailserver.pauladuartetango.com/uploads/1/3/0/2/130287973/130287973.html#nashville+tennessee+visitor+guide, which likely leads to a phishing or malware distribution site.

  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
