MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links to other PDF files hosted on various domains. This pattern is indicative of a link farm or a mechanism to distribute content across multiple sites. The primary URL points to a document titled 'Caracteristicas de la alta edad media resumen', suggesting a lure to disguise the malicious intent. The heuristic 'PDF_SEO_LINK_FARM' strongly suggests this is not a legitimate document but rather part of a larger scheme.

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.
