MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a heuristic firing indicating a link farm with 30 external links, predominantly hosted on 'www.felderandbrent.com'. The document body also contains a URL pointing to 'disastersupply.org'. These findings suggest the document's primary purpose is to redirect users to a network of external sites, likely for SEO manipulation or to serve malicious content. No scripts were extracted from this sample.

Heuristics 3

  • 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.
