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

The PDF document contains a large number of embedded external links, many of which point to other PDF files hosted on various domains. This behavior is indicative of a link farm or SEO spam campaign, designed to drive traffic to potentially malicious or low-quality content. The primary heuristic firing, PDF_SEO_LINK_FARM, directly supports this assessment. The document body itself contains the title 'Consecuencias del incumplimiento de las obligaciones en derecho romano' which appears to be a lure for the link farm.

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.
