T1204.002 Malicious Link
The PDF document contains a large number of external links, many of which point to other PDF files hosted on various domains. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass external PDF link farm, suggesting a tactic to manipulate search engine results or distribute content across many sites. The document body contains the phrase 'Les miserables resumen pelicula', which appears to be a lure to attract users to click on the embedded links. No scripts were extracted from this sample.

-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall 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_URIPDF contains an external URL action
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe 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_URLOne 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.URL http://estudio-thuban.com/uploads/1/3/0/7/130739878/130739878.html#les+miserables+resumen+pelicula PDF link annotation
