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

This PDF document contains a large number of external links, a technique often used for SEO link farms or to direct users to malicious content. The document body, though partially corrupted, contains a reference to 'Puerta de baño vidrio templado' and includes multiple URLs pointing to various domains, suggesting a lure to external content. The PDF_SEO_LINK_FARM heuristic firing confirms the presence of a mass external link farm within the PDF.

Machine Learning

  • Nyx PDF Classifier malicious score 1.0000

Heuristics 4

  • 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
  • Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL
    The same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
  • 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.
