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 numerically or generically named PDFs, suggesting a link farm for SEO manipulation. The document body text, though partially corrupted, contains a reference to 'El internado temporada 2 capitulo 3 completo' and includes multiple URLs. The primary heuristic 'PDF_SEO_LINK_FARM' indicates the document's purpose is to host a mass of external links. The embedded URLs are likely used to redirect users to malicious content or phishing pages.

Heuristics 3

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
